A team of astronomers said that they have detected a new young and warm exoplanet orbiting a distant star which is estimated to be similar in size and mass to Jupiter.&nbsp;

The findings, which were published on April 3 in the pre-print server arXiv, revealed that the newfound alien world has been designated TOI-4862 b (or NGTS-30 b).&nbsp;

"With a moderate eccentricity of 0.294, its equilibrium temperature could be expected to vary from 274 K to 500 K over the course of its orbit," the research mentioned. &nbsp;

The study said that the new long-period transiting exoplanet was detected by the astronomers following up on a single-transit candidate found in the Transiting Exoplanet Survey Satellite (TESS) mission.&nbsp;

The National Aeronautics and Space Administration's TESS has identified more than 7,100 candidate exoplanets (TESS Objects of Interest, or TOI). The study said that out of the total, 432 have been confirmed so far.&nbsp;

The satellite has been conducting a survey of about 200,000 of the brightest stars near the sun. It focuses on searching for transiting exoplanets.&nbsp;

The prime mission of TESS ended on July 4, 2020, but it currently in an extended mission. NASA once said in its report that TESS is finding planets ranging from small, rocky worlds to giant planets, showcasing the diversity of planets in the galaxy.&nbsp;

A group of astronomers led by Matthew Battley of the University of Geneva in Switzerland has confirmed another TOI monitored by TESS.&nbsp;

The astronomers have identified a transit signal in the light curve of the exoplanet, which is a young G-type star located some 762 light years away.&nbsp;

The researchers wrote in the paper: "NGTS-30 b/TOI-4862 b was first discovered via a single transit in TESS photometry, before archival photometry from NGTS [Next Generation Transit Survey] and EulerCam were used to refine the planetary period."&nbsp;

Scientists have finally found out what's happening to the National Aeronautics and Space Administration (NASA)'s pioneering Voyager 1 spacecraft, and what's behind the gibberish sounds coming from it in November. NASA launched the space probe Voyager 1 in 1977 to study the outer Solar System, the interstellar space beyond the Sun's heliosphere.&nbsp;

Voyager 1, which is the most distant spacecraft to Earth, has been acting weird and talking gibberish on the interplanetary "radio". It has left the scientists perplexed.&nbsp;

NASA previously said that the engineers and other experts were working to resolve an issue with one of Voyager 1's three onboard computers, called the flight data system (FDS).&nbsp;

The FDS collects data from the science instruments and works on compiling information into a data package when it works properly. It also tells about the health and status of the spacecraft.&nbsp;

The data is then transmitted back to Earth using the telecommunications unit (TMU) once compiled.&nbsp;

Voyager 1: Scientists finally know reason behind glitchy sound coming from space

The National Aeronautics and Space Administration (NASA) on Friday (Apr 5) released images of a mysterious silver surfboard-shaped object which was orbiting the Moon.

The National Aeronautics and Space Administration (NASA) on Friday (Apr 5) released images of a mysterious silver surfboard-shaped object which was orbiting the Moon. The identity of the object, which was captured by NASA's Lunar Reconnaissance Orbiter (LRO) last month, has now been revealed. LRO has been circling and studying the Moon for 15 years. The curious souls might think it's an Unidentified flying object (UFO), but it's not. Also read: Moon once 'literally turned itself inside out'. Scientists wonder 'how' NASA revealed that LRO last month captured several images of Korea Aerospace Research Institute's Danuri lunar orbiter, which may appear to be mysterious unless explained. NASA said that the two spacecraft zipped past each other in opposite directions between March 5 and 6, 2024. Both spacecraft were travelling in nearly parallel orbits. Danuri is Korea's first spacecraft on the Moon and has been in lunar orbit since December 2022. Also read: A violent end awaits our solar system as all planets will be 'crushed' to dust one day NASA said in its reports that the LRO operations team at Goddard Space Flight Center in Greenbelt, Maryland needed "exquisite timing" in pointing LROC to the right place at the right time to catch a glimpse of Danuri. The task, however, was not easy because of the fast relative velocities between the two spacecraft, which is about 11,500 kilometres per hour. The American space agency said that LRO's narrow-angle camera captured the images during three orbits that happened to be close enough to Danuri’s to grab the images. To be clear, the Danuri orbiter is not a weirdly thin load of pixels—it's a fairly normal-looking orbiter. But the terrific speeds involved mean that it's smeared on the LRO's camera detector.

It has emerged as an invaluable contribution to the study of the Moon. "Although LRO's camera exposure time was very short, only 0.338 milliseconds, Danuri still appears smeared to 10 times its size in the opposite direction of travel because of the relative high travel velocities between the two spacecraft," NASA said in its report.

Elon Musk has been vocal about his aim to colonise Mars one day. The CEO of SpaceX and Tesla Motors has delivered another speech about his off-world fantasy. He gave a "tangible" roadmap to inhabiting the Red Planet.

Elon Musk has been vocal about his aim to colonise Mars one day. The CEO of SpaceX and Tesla Motors has delivered another speech about his off-world fantasy. He gave a "tangible" roadmap to inhabiting the Red Planet. Musk provided the "overall path to making life multi-planetary" in a presentation to SpaceX employees at the company's Starbase facility in Texas. During the presentation, he said that although Falcon 9 is the primary launch vehicle for Earth's orbit, Starship will ultimately bring life to other worlds. Starship is the aeronautics company's largest and most powerful rocket. However, it hasn't managed to launch into orbit and then, land without destroying it. According to Musk, Starship will be capable of ferrying the massive payloads to orbit necessary to carry out large-scale Mars missions. "We need enough people and enough tonnage on Mars such that Mars can survive and continue consciousness even if something were to happen to Earth," he said. In the past, Starship has suffered many failures, like exploding during several test flights. It had its most successful run in the third and most recent launch last month and reached space for the second time. However, it didn't survive re-entry and crashed into the ocean. ALSO READ | Feeling furious? Write it down and throw away the paper, a Japanese way of ‘eliminating’ anger While the fourth test will require landing the Starship booster on a "virtual tower" in the ocean, the fifth would be to catch the booster with an actual launch tower in Starbase. "My guess is probably next year is when we will be able to reuse Starship," Musk said. So far, SpaceX has successfully conducted 327 Falcon launches. Musk plans on making a reusable "Starship 2," which will supposedly carry 100 tons of cargo to orbit. "Starship 3 will carry upward of 200 tonnes and cost less per flight than Falcon 1," Musk claimed. To send millions of tonnes of cargo to Mars, SpaceX estimates that it will need to build several thousand vehicles per year and conduct ten launches every day. "I think this is pretty doable," Musk said. "We're going to do this." Some experts have cast doubt on Musk's Martian ambitions. Starship must prove capable of carrying out its role in NASA's mission, Artemis 3, to land on the Moon. (With inputs from agencies)

‘I think this is pretty doable,’ says Elon Musk on Mars settlement plans

Our Earth has witnessed several “Snowball” periods during its history. During these periods, the entire planet remained covered in ice for thousands and even millions of years. For long, scientists have debated over one question: What could have triggered the initiation of the snowball periods? Now, a study has claimed that the process might have been triggered by large asteroids that slammed into Earth.

The study, published in the journal Science Advances, has been prepared by scientists from Yale, the University of Chicago and the University of Vienna.

<h2>Previous theory</h2>

According to one theory, the ice age might have begun due to a massive decline in greenhouse gases in the atmosphere. However, scientists still wanted to explore other possibilities.

Lead author of the study, Minmin Fu, the Richard Foster Flint Postdoctoral Fellow in the Department of Earth and Planetary Sciences in Yale’s Faculty of Arts and Sciences, said in a statement: “We decided to explore an alternative possibility.”

“What if an extraterrestrial impact caused this climate change transition very abruptly?” Minmin added.

<h2>How the study was conducted?</h2>

The scientists used a climate model and aligned it with characteristics of the aftermath of an asteroid strike in four different periods of the past: Preindustrial (150 years ago), Last Glacial Maximum (21,000 years ago), Cretaceous (145 to 66 million years ago), and Neoproterozoic (1 billion to 542 million years ago).

Scientists concluded that while the asteroid strike was unlikely to trigger a snowball in two warmer periods (Cretaceous and preindustrial), it could have triggered one in the other two periods as the temperature in climate was already low.

The temperature in the Glacial Maximum and Neoproterozoic periods was cold enough to set in motion an ice age.

“What surprised me most in our results is that, given sufficiently cold initial climate conditions, a ‘Snowball’ state after an asteroid impact can develop over the global ocean in a matter of just one decade,” said co-author Alexey Fedorov, a professor of ocean and atmospheric sciences in Yale’s Faculty of Arts and Sciences.

Large asteroids that slammed into Earth could have triggered ice age: Study

On days when you feel like punching someone, try grabbing a pen and paper instead. A new research shows that writing down all that wrath on a piece of paper and throwing it away, not only helps in reducing anger but can also eliminate it completely.&nbsp;

A study conducted at Nagoya University in Japan found that shredding the paper with words describing your frustration might be a good way to calm oneself down instantly. This is preferably a better option in a workplace setting, where expressing furious thoughts openly can have dire consequences.&nbsp;

What researchers found from the study was something that even they didn’t expect. They found that this method not only suppressed the furious emotion but also eliminated the anger “almost completely,” said lead researcher Nobuyuki Kawai.

Kawai is a doctoral student at Nagoya University, who conducted the study along with another doctoral student Yuta Kanaya. Both asked the participants to write brief opinions on social problems like smoking in public.&nbsp;

Upon completing the assignment, they told the participants their responses would now be checked by a doctoral student at Nagoya University. Instead, there was no such “doctoral student” to evaluate the responses and all participants were sent the same feedback of poor intelligence and lack of logic and rationality.

Each participant was given the same insulting remark: "I cannot believe an educated person would think like this. I hope this person learns something while at the university."

Afterwards, the participants were asked to write their thoughts on the feedback, focussing on what triggered their emotions.

They were then split into two groups. The first group was told to either throw away the paper they wrote in the garbage or keep it in a file on their desk. A second group was told to destroy the document in a shredder or put it in a plastic box.

The participants were then asked to rate their anger after disposing or keeping the paper.

The majority of the participants reported a higher level of anger after receiving insulting comments. However, individuals who discarded the paper in a trash can or shredded it returned to their initial state after throwing away the paper.

Meanwhile, the participants who held on to a hard copy of the insult experienced only a small decrease in their overall anger.

"This technique could be applied at the moment by writing down the source of anger as if taking a memo and then throwing it away when one feels angry in a business situation," explained Kawai.

This method of anger management is somewhat similar to the Japanese cultural tradition of hakidashisara, an annual festival at Hiyoshi shrine near Nagoya where people smash small discs representing things that make them angry. Many anecdotes reported people feeling relieved after their participation in the festival.&nbsp;

This method of anger management is somewhat similar to the Japanese cultural tradition of hakidashisara, an annual festival at Hiyoshi shrine near Nagoya where people smash small discs representing things that make them angry. Many anecdotes reported people feeling relieved after their participation in the festival. (With inputs from agencies)

Feeling furious? Write it down and throw away the paper, a Japanese way of ‘eliminating’ anger

Scientists, in a path-breaking discovery, have found a nearby alien planet which has&nbsp;one side locked in permanent darkness while the other side remains in endless sunshine.

This is the first major evidence which proves that the planets beyond our Solar System are also 'tidally locked' to their host stars and have an orbital period exactly similar to the rotational one.&nbsp;

This&nbsp;results in one side of the exoplanet always facing the star and not having any respite from the heat and the other side facing perpetual night.

The exoplanet, which is known as LHS 3844b, or Kua'kua, is close to its host star Batsu which is seen as uninhabitable to life.

<h2>What are tidally locked exoplanets?</h2>

Tidal locking is a cosmic phenomenon which has been observed inside the Solar system, although it has not been found in any of the planets revolving around the Sun.

Tidal locking happens when the rotation cycle of two cosmic bodies slowly synchronises with their orbit because of gravitational interaction.&nbsp;

However, the findings have finally confirmed that tidally locked exoplanets also exist outside our solar systems and may be common in the Milky Way.

"This thing that has been theoretical now feels real," said astronomer Nicolas Cowan of McGill University in Canada, while speaking to Nature. "This is actually what these planets look like," he added.

As per the research, Kua'kua also doesn't have an atmosphere which means that any temperature readings are related directly to its surface.

Scientists discover first alien Super-Earth with permanent dark and sun-lit sides

One of the most dramatic changes a woman’s body goes through is when she becomes pregnant and passes through the beautiful process of bringing a new human to life. During nine months and several months after, a woman goes through a lot of changes, both mentally and physically, as we are already aware.

A recent study suggests that pregnancy has an effect on women’s biological age as well. Women who have been pregnant showed more signs of biological ageing compared to women who had never been pregnant before, as per a study published in Proceedings of the National Academy of Sciences.&nbsp;

In other words, the more times a woman has been pregnant, the faster is her biological ageing.

<h2>Pregnancy has long-term effects on woman’s body, shows study</h2>

Calen Ryan is an associate research scientist at the Columbia University Ageing Center at the Mailman School of Public Health. She along with her team studies data from more than 1700 people in the Philippines who were part of a survey.&nbsp;

At the start of the study, in 2005, all the participants were of the age group 20-25. They all provided their blood samples and answered a few questions on their reproductive and sexual history, including questions like how many times they had been pregnant and whether or not those pregnancies resulted in live births.&nbsp;

All of the blood samples were analysed for several biological factors associated with ageing. As our cells age, they accumulate molecular imprints of genes that have been turned on or off, and these can serve as a proxy for how biologically older the cells are. These are called “epigenetic clocks” that make cells either older or younger than their actual chronological age.

Ryan and his team used six such epigenetic clocks, which assessed 19 different indicators. The study found that “women who had been pregnant at least once were biologically older than women of the same age who had not been pregnant.”

Further, the study found, that pregnancy led to anywhere from four months to more than a year of faster ageing, at a rate of about 3 per cent more per year than women who had never been pregnant.

Also, women with more than one pregnancy aged up to five months faster as compared to women with one or fewer pregnancies.&nbsp;

Pregnancy takes a toll on the biological age of women: Study

In China, doctors have successfully transplanted a pig's kidney with multiple gene edits into a brain-dead human recipient. The transplantation, as per reports, has been "working continuously for 13 days."

<h2>First time in China</h2>

This was the first of its kind operation in China and comes after similar transplants in the United States.

The procedure was done on March 25 by a team of doctors that only a couple of weeks back performed a successful pig liver transplant.

"As of April 7, the transplanted kidney has been working continuously for 13 days,"&nbsp;Qin Weijun, director of the Air Force Medical University Xijing Hospital, told Science and Technology Daily on Monday.

"It is functioning well in the recipient's body and producing urine normally."

To do this, scientists used CRISPR/Cas9 gene-editing technology to add two human genes to the pig used in the transplant. Additionally, they removed three pig genes that can cause hyperacute rejection, said the university.

Harvard professor Avi Loeb, who is known for investigating the existence of aliens, in&nbsp;fresh claims has stated that&nbsp;aliens are likely to be present 300 feet below Earth's surface.

Notably, the United States government has never confirmed any mysterious sightings of UFOs. Avi Loeb has said that aliens have been using hidden dimensions created by researchers at the CERN particle accelerator to enter Earth.

The accelerator, the Large Hadron Collider (LHC), blasts particles at the speed of light to recreate a situation similar to that of the Big Bang, with hopes of finding hidden dimensions which will reveal how the universe was formed.

Speaking about the hidden aliens, Loeb said that the extra-terrestrial creatures have most likely spent billions of years developing dimension-hopping technology.

<h2>Only particle accelerators such as CERN can detect these dimensions: Loeb</h2>

The physicist further claimed that the aliens may have been using theoretical quantum gravity engineering to travel through 'curled' dimensions which&nbsp;humans can detect only in particle accelerators such as CERN.

In the documentary, 'The Paranormal UFO Connection', the Harvard scientist says that if some day alien technology reaches us,&nbsp;we will be completely dumbfounded.

"Just like a cave dweller coming to a city like London or Europe, and seeing all the technological gadgets there," said Loeb.

"There will be a sense of religious awe, and we wouldn't understand it, especially if we are dealing with the effects of quantum gravity that we have any clue about," he added.

Loeb claimed that using extra-spatial dimensions to travel will mean that there is&nbsp;a 'much smaller' chance of collisions.

At CERN, scientists have made an attempt to detect six 'extra spatial' dimensions and find particular particles as evidence in such existing dimensions.

"Quantum mechanics was discovered exactly a century ago. And all the most sophisticated technologies we currently employ, such as the Internet, artificial intelligence, and so forth, rely on our understanding of quantum mechanics," said Loeb.

"But the process of learning is incomplete - there are several major puzzles in modern physics. Within the mainstream of theoretical physics for the past decades, the prevailing paradigm is that it is possible to unify quantum mechanics and gravity unless you work with extra-spatial dimensions," he added.&nbsp;

Aliens have likely travelled to Earth via 'curled dimensions', claims Harvard professor

Solar eclipses, which are arguably one of the most fascinating astronomical events to witness, can now be created on demand. The scientists in Europe have come up with a way to produce artificial eclipses.&nbsp;

Under the project, which the scientists have named Proba-3, they plan on aligning two spacecraft in order to create the 'eclipse on demand'. By constructing this intricate calibration, the project aims at accomplishing the first-ever precision formation space flight and also plans to obtain fresh views of the Sun.

Earlier, the European Space Agency (ESA) during an event in Belgium last week, revealed the Proba-3 satellites, the Coronagraph and the Occulter.

As per the plan unveiled by ESA, the Occulter is set to fly around 150m from the Coronograph.

Once both the satellites reach their exact locations, the Occulter will project a shadow onto the Coronagraph face, further masking the sun to reveal the corona.

"The two spacecraft will act as if they are one enormous 150 metre-long instrument," said the ESA's Director of Technology, Engineering and Quality, Dietmar Pilz.

"Achieving this will be extremely technically challenging, however, because the tiniest bit of misalignment and it won't work," Pilz said.

"The development process has been correspondingly long, undertaken by a consortium of smaller ESA Member States led by Spain and Belgium. So I am very pleased to see Proba-3 here today, being prepared for launch," he added.

An experiment on similar lines was conducted in the year 1975 when astronauts from the United States and the Soviet Union collaborated to create an artificial eclipse.&nbsp;

However, Proba-3 aims to carry out the feat in a routine manner successfully.

“It will demonstrate various types of formation flying configurations and it will experiment with in-orbit rendezvous techniques,” Pilz said.

“Once proven, formation flying will be an enabler for future missions,” he added.

Scientists come up with project to create on-demand solar eclipses

A recent study, published in Nature Geoscience, showed alarming concentrations of persistent "forever chemicals" in surface and groundwater globally. Hotspots included Australia, the United States, and Europe. These chemicals, known as PFAS, are commonly found in everyday products like non-stick pans and food packaging. Despite their ubiquitous presence, PFAS have been linked to serious health problems such as cancer and birth defects. The study, analysing 45,000 water samples worldwide, found many exceeded recommended PFAS levels, posing potential risks to human health, especially in water sources used for drinking.

These chemicals, found everywhere from turtle eggs to Antarctic snow, were also detected in surface water and groundwater, which humans rely on for drinking.

"Many of our source waters are above PFAS regulatory limits," Denis O'Carroll, one of the study's authors and a professor at the University of New South Wales in Australia told AFP.

O'Carroll noted that while it was previously understood that the numerous varieties of forever chemicals were widespread in the environment, he was surprised by the significantly higher sampled levels compared to recommended thresholds.

<h2>Other findings from the study</h2>

The study revealed that 69 percent of groundwater samples worldwide exceeded Canada's minimum standards for PFAS, with six percent surpassing the EU's standard.

Australia, China, the United States, and parts of Europe emerged as global hotspots with elevated PFAS concentrations.

Despite concentrated testing in certain areas, the study said&nbsp;that comparable results could be found worldwide with more extensive research.

A recent study has suggested&nbsp;that families of men diagnosed with infertility might face a higher risk of specific cancers, such as colon and testicular cancers. While it's known that infertility in men often accompanies various health issues, including cancer and heart-related diseases, researchers sought to investigate if these risks extended to their families.

Researchers used algorithms to analyse data, in an effort&nbsp;to develop a more personalised approach to assess cancer risk. By understanding potential genetic and environmental factors impacting cancer risk in these families, better preventive measures could be implemented.

The study's findings could facilitate more meaningful discussions between men with infertility and their healthcare providers. Increased awareness of potential cancer risks within the family could prompt proactive screening and preventive measures.

A recent study has suggested that families of men diagnosed with infertility might face a higher risk of specific cancers, such as colon and testicular cancers. While it's known that infertility in men often accompanies various health issues, including cancer and heart-related diseases, researchers sought to investigate if these risks extended to their families.

A recent study has suggested that families of men diagnosed with infertility might face a higher risk of specific cancers, such as colon and testicular cancers. While it's known that infertility in men often accompanies various health issues, including cancer and heart-related diseases, researchers sought to investigate if these risks extended to their families. Researchers used algorithms to analyse data, in an effort to develop a more personalised approach to assess cancer risk. By understanding potential genetic and environmental factors impacting cancer risk in these families, better preventive measures could be implemented. The study's findings could facilitate more meaningful discussions between men with infertility and their healthcare providers. Increased awareness of potential cancer risks within the family could prompt proactive screening and preventive measures.

Study finds infertility in men tied to higher risk of cancer in families

Chinese researchers have published a paper claiming to have found a prehistoric tapeworm partially intact inside a sample of 100-million-year-old amber. The mid-Cretaceous Kachin amber was discovered in Myanmar. According to the scientists at the Nanjing Institute of Geology and Paleontology at the Chinese Academy of Sciences, the discovery of a tapeworm from this era is extremely rare, and it could bear the traces of DNA of its prehistoric host.

Tapeworms span from less than one millimetre to over 30 metres in length. They can infect humans, and livestock and live in almost all kinds of environments.

The discovery indeed is fascinating and reeks of the beginning of the Sci-fi movie&nbsp;Jurassic Park, where scientists used prehistoric mosquito remains to extract the DNA from extinct creatures from a time when dinosaurs ruled the Earth.

According to Luo Cihang, the first author of the study, “The current find is the most convincing body fossil of a platyhelminth ever found.”

<h2>The tapeworm may be carrying the DNA of dinosaurs</h2>

As per the research, the tapeworm might have hooked itself to the intestine of a host belonging to the Early Cretaceous period. The Cretaceous is usually noted for being the last portion of the "Age of Dinosaurs."&nbsp;

It could mean that the tapeworm may be carrying DNA samples of various dinosaurs, including the large, meat-eating deinonychus, the horned carnotaurus, or a massive carcharodontosaurus, which boasted a bigger skull than a tyrannosaurus rex.

<h2>Host creature might be marine dinosaur</h2>

The study highlights that the amber was deposited into the amber on shore, indicating its host might have been a marine dinosaur. According to one theory, the host may have been trapped on land and died, causing the tapeworm to detach itself from the host’s intestine and move out of the body and into sticky amber.

As per another theory, the sea creature which hosted the tapeworm might have been eaten by a land-roaming dinosaur. As and when its host was being eaten, the tapeworm would have made its way out and be stuck in the amber.

Scientists have been studying the hundreds of volcanoes which have been hiding silently under the thick and frosty layers of snow in Antarctica and trying to estimate what are the chances of their eruption.

Scientists have been studying the hundreds of volcanoes which have been hiding silently under the thick and frosty layers of snow in Antarctica and trying to estimate what are the chances of their eruption. It is not very well-known that the western ice sheet which covers the continent is considered the largest volcanic region present on Earth, with around 138 volcanoes. Among those volcanoes, the geologists had discovered 91 of them as part of a study which was carried out in 2017 and published in the journal Geological Society. Also Read: Mysteries of Antarctic: Researchers find 13 new papillomaviruses in seals Here's what the geologists found about the chances of eruption of volcanoes While studying the volcanoes, which come into existence on the surface of the Earth as an expression of the heated material exiting from its interior, the scientists were unable to "distinguish whether or not [they] are volcanically active," wrote the study authors. At present, two volcanoes of the continent have been classified as active, which are: Mount Erebus and Deception Island. These two are said to be the southernmost active volcano in the world. Speaking to Live Science, Conor Bacon, a postdoctoral research scientist at the Lamont-Doherty Earth Observatory at Columbia University in New York, said, "Erebus, which looms over the McMurdo research base on Scott Island, has been continuously erupting since at least 1972." Since then, Mount Erebus has been seen to "emit plumes of gas and steam" and even occasionally spew out rock "bombs," which collectively are called strombolian eruptions, as per the NASA Earth Observatory. "One of its most interesting features is the persistent lava lake that occupies one of [its] summit craters, where molten material is present at the surface," said Bacon. Watch: Scientists in Antarctica warn of Bird Flu outbreak as penguin cases confirmed "These are actually quite rare, as it requires some very specific conditions to be met to ensure the surface never freezes over," he added. Meanwhile, Deception Island is the caldera of an active volcano which had last erupted in 1970, as per the data collected by Deception Island Antarctic Specially Managed Area that monitors the volcanic activity on the island. Even though there are two active volcanoes on the continent, Antarctica is filled with fumaroles and volcanic vents which release vapours and gases into the air. Even though scientists have been monitoring the volcanoes of Antarctica with instruments, it can be challenging to predict when the next one will erupt. (With inputs from agencies)

A recent study has revealed a bizarre situation in which our Moon had once completely turned itself inside out.&nbsp;

A new paper was published by a team of scientists from the University of Arizona Lunar and Planetary Laboratory on the evolution of the lunar interior.

In the paper, they emphasised the ancient lunar interior's instability. The paper, which was published in the journal Nature Geoscience, spoke in detail about how the Moon had evolved in a chaotic manner.

In a press statement, study co-author and LPL associate professor Jeff Andrews-Hanna said, “Our moon literally turned itself inside out. But there has been little physical evidence to shed light on the exact sequence of events during this critical phase of lunar history, and there is a lot of disagreement in the details of what went down – literally.”

<h2>How was the Moon formed?</h2>

Scientists have estimated that the moon was formed roughly 4.5 billion years ago when a small planet smashed into Earth.&nbsp;

Because of the impact, the molten rock spread into space and slowly started orbiting around our planet. Through time, the rock solidified and formed our Moon.

In the lunar rock samples which were collected by the Apollo astronauts, new information has been provided about the ancient history of the Moon.&nbsp;

Later, in the satellite observations, it was found that the volcanic rocks were prominent on the nearside of the Moon.

A new model created by the researchers of the University of Arizona has explained why this is the case.

When the Moon was first formed, it was most likely covered by a global magma ocean. Once the molten rock cooled, it formed the mantle and the outer crust of the Moon.&nbsp;

The computer models showed how the magma which was under the crust had crystallised into dense minerals, which included ilmenite and contained titanium and iron.

“Because these heavy minerals are denser than the mantle underneath, it creates a gravitational instability, and you would expect this layer to sink deeper into the moon’s interior,” explained Weigang Liang, who headed the research as part of his doctoral work at LPL.

Later, the dense material sank in the interior of the Moon and melted and mixed with the mantle. Eventually, it came back to the surface through the titanium-rich lava which flows visibly on the surface.

The scientists, in their research, found that the gravity field of the Moon can be used to map the distribution of remnants of ilmenite, which were formed after the dense material sank in the lunar mantle.

The observations made by NASA’s Gravity Recovery and Interior Laboratory (GRAIL) lunar satellite were used by the scientists.

“Our analyses show that the models and data are telling one remarkably consistent story. Ilmenite materials migrated to the near side and sunk into the interior in sheetlike cascades, leaving behind a vestige that causes anomalies in the moon’s gravity field, as seen by [NASA’s] GRAIL," Liang said,&nbsp;

Moon once 'literally turned itself inside out'. Scientists wonder 'how'

For years, we have known that our Earth will one day be swallowed by the Sun as it will balloon because of its extinguishing fuel.&nbsp;

However, a new study has highlighted the death of Earth and other planets may be more chaotic and violent than ever imagined by human civilisation.

As per the researchers at the University of Warwick, even if our planet gets swallowed by the Sun, other planets are likely to be 'crushed and ground to dust'.&nbsp;

<h2>How will the Sun die?</h2>

Sun, along with other similar stars, crush the hydrogen atoms into helium which generates heat and light under the forces of gravity.

There is a limited amount of hydrogen in all stars and when this begins to run out, the forces which help in keeping the star stable lose balance.&nbsp;

After around five billion years, our Sun will begin burning in its core before it starts to inflate and grow more than 200 times its original size and the helium on its outer layers will start to burn.

Once this happens, the Sun will leave behind a white dwarf which will be a remnant of the core of the Sun and will glow with residual heat as it cools down.

<h2>How will the solar system get destroyed after the Sun's death?</h2>

The University of Warwick's Professor Boris Gaensicke, speaking about the solar system's destruction, said, "The sad news is that the Earth will probably just be swallowed up by an expanding Sun before it becomes a white dwarf."

However, till now scientists do not know much about what will happen to the rest of the solar system once the sun turns into a white dwarf.&nbsp;

The researchers looked into the fate of moons, planets and asteroids which will pass close to the white dwarfs by looking into the transits.

The researchers found that around the white dwarf stars, the transits were irregular and highly chaotic, which hinted at the fact that their future is likely to be violent and catastrophic.

Moons, asteroids and planets which come close to the white dwarf's dense core are shredded when they get pulled into smaller pieces by gravity. These pieces eventually get grounded into dust as they collide with one another.

The dust continues to move around the dead star till it eventually disperses out into the universe. This is likely to be the fate of the many celestial bodies in our solar system which are not swallowed or destroyed by the expansion of the sun.

"For the rest of the solar system, some of the asteroids located between Mars and Jupiter, and maybe some of the moons of Jupiter may get dislodged and travel close enough to the eventual white dwarf to undergo the shredding process we have investigated," said Professor Gaensicke.

Meanwhile, Dr Amornrat Aungwerojwit of Naresuan University, Thailand, who headed the study, said: “Previous research had shown that when asteroids, moons and planets get close to white dwarfs, the huge gravity of these stars rips these small planetary bodies into smaller and smaller pieces.”

“Collisions between these pieces eventually grind them into dust, which finally falls into the white dwarf, enabling us to determine what type of material the original planetary bodies were made from," he added.&nbsp;

The best weather for the eclipse is likely to remain from Vermont through Maine and also in Missouri through southern Indiana. In these areas, only a few isolated clouds are likely to hover in the sky, which is not likely to obstruct&nbsp;optimal eclipse viewing. So, all the eclipse watchers can expect to see the astronomical phenomenon clearly in places like Evansville, Ind.; Carbondale, Ill.; Burlington, Vt.; and Caribou, Maine.

It is expected that the eclipse will move from south central Texas through the Ohio Valley and into New England before going to northeast Canada and will cast a seconds-long shadow of darkness.

Here's how the weather is likely to be in major cities on the path of totality:

<h2>New York City</h2>

New York is most likely to observe good weather and some clouds through which one can see and will not face complete obstruction&nbsp;of the historic solar eclipse.&nbsp;

<h2>Austin and Texas&nbsp;</h2>

Texas and Austin are likely to witness an overcast sky during the eclipse which will make it difficult for viewing. It is also likely to observe severe storms later in the day. &nbsp;

<h2>Buffalo</h2>

Earlier, the sky was looking clear in Buffalo. However, it appears fairly overcast now and the forecasters say that the&nbsp;eclipse will most likely not be visible from the region.&nbsp;

<h2>Cincinnati, Cleveland, and Columbus</h2>

The skies are going to remain cloudy in Cincinnati and Columbus but they are likely to get clearer and the eclipse should be visible to people. A better viewing opportunity will be possible from Toledo in Ohio.

In Cleveland also, the skies&nbsp;are likely to clear up&nbsp;till the time the eclipse moves through the region.

<h2>Dallas</h2>

Scattered storms and overcast skies during the eclipse have been forecasted by the National Weather Service in Dallas. The weather is likely to deteriorate in the region after the eclipse. &nbsp;“There may only be a short window (1-2 hrs) between the eclipse and strong to severe storms,” stated the National Weather Service in Dallas.

<h2>Indianapolis</h2>

The skies in Indianapolis, which lies in the path of totality, will get&nbsp;clearer and the eclipse will be easily visible.

<h2>Louisville</h2>

The conditions will remain fine in Louisville for viewing the eclipse. If there is any cloud coverage, it will be clear away before the eclipse reaches the region.

<h2>Rochester&nbsp;</h2>

There will be 80 percent cloud coverage in Rochester which is on the eclipse’s path of totality.&nbsp;

<h2>San Antonio</h2>

The weather conditions in San Antonio are also not too good and the skies are likely to be covered with clouds which will hinder the experience of viewing the solar eclipse.

Total Solar Eclipse 2024: Will weather ruin your solar eclipse watch party? Here's what the forecast says

What do most people look for in other individuals when hunting for a romantic partner? You might say physical attractiveness, wealth or socioeconomic status. However, a recent study has dismissed this widely-held notion. As per the study, conducted in Brazil and published in the Archives of Sexual Behavior, most people prioritise intelligence and kindness as the most sought-after traits when choosing a partner.

The findings were consistent regardless of sexual orientation.&nbsp;

“Choosing a romantic partner is a very ordinary, but also extremely intriguing process,” said study author Joao Francisco Goes Braga Takayanagi of the Institute of Psychology at the University of Sao Paulo.

“We may know immediately that we are attracted to someone, but we might not know exactly why we are attracted to them, or even if that attraction is any proof that they will be a good match for us. I am fascinated by relationship science because it helps us understand something that is universal, but also quite mysterious and important to all of us, ” Joao Francisco added.

<h2>Sample size</h2>

&nbsp;The study included 778 participants, aged between 18 and 64. The group comprised people of different sexual orientations: heterosexual, bisexual, and homosexual men and women.

The participants were asked to create their ideal partner based on a set of traits: Intelligence, kindness, physical attractiveness, health, and socioeconomic status.

All of the participants were also given three different budget scenarios: low, medium, and high, to find out how people’s priorities change with the change in the availability of resources.

<h2>Results</h2>

Intelligence and kindness emerged as the most desired traits by people of all age groups, regardless of their sexual orientation.

However, with special emphasis placed on sexual orientation, some other traits also emerged as most desired. For example, Heterosexual men said physical attractiveness played a major role when choosing partners.

Conversely, individuals attracted to men (including heterosexual women, homosexual men, and bisexual individuals) showed a higher preference for socioeconomic status.

“Also, social status seems to be especially important for men’s appeal, since both heterosexual women and gay men valued this trait more in relation to other groups. Still, if you want to attract more potential partners, working on your brains and personality seems to be your best bet,” Takayanagi was quoted as saying by PsyPost.

NASA's Curiosity rover is currently in the twelfth year of its mission to investigate Mars. Till now, it has reached several places where no other rover has gone before.

NASA's Curiosity rover is currently in the twelfth year of its mission to investigate Mars. Till now, it has reached several places where no other rover has gone before. Recently, the Curiosity rover's adventures brought it to Gediz Vallis. a winding and boulder-choked channel some scientists believe is the desiccated bed of an ancient river. They will try to investigate more about its past and find out how the landform came to be in the first place. The Curiosity rover was originally slated for a two-year mission. However, it continues to trawl the Martian surface. It has provided several new insights about the red planet and its environment. The rover's findings have led scientists to believe that life might have once lived or still lives on Mars. Since 2014, the rover has been driving up the slopes of Mount Sharp, which towers 3 miles (5 kilometres) above the rover's initial landing location in Gale Crater. Mount Sharp and the rest of Mars would've been significantly wetter billions of years ago than it is today. However, Mars has dried up over time and the wind and remnant water has eroded the mountain into the layers Curiosity can see today. ALSO READ | Travelling 650 million light-years, a mysterious signal possibly from a star corpse has reached Earth According to scientists, some force carved the Gediz Vallis channel on the mountain's slope as it was in the process of drying up. Although it's possible that wind created Gediz Vallis, the channel's sides are steeper than scientists would expect from a wind-carved vale. There's a high chance that the channel spotted by Curiosity on Gediz Vallis' floor was formed by landslides from higher up the mountain, which could have deposited boulders and other rocky debris. Another intriguing prospect is that it was formed by the flow of liquid water. "If the channel or the debris pile were formed by liquid water, that's interesting. It would mean that fairly late in the story of Mount Sharp, after a long dry period water came back, and in a big way," said Ashwin Vasavada, Curiosity's project scientist at NASA's Jet Propulsion Laboratory, in a statement. The Curiosity rover will spend several months exploring the channel, not just to study the Martian history but also to learn more about what lies beyond. As it is unable to climb Mount Sharp, the best way for the rover to investigate the area is by looking up from the channel, allowing scientists to gain insights into what lies ahead.

NASA’s Curiosity rover starts exploring possibly dried-up ancient water body on Mars

Across the United States, Mexico and Canada, observers would get a feel of "day turning into night" during Total Solar eclipse on April 8, 2024. This is an astronomical phenomenon that occurs once in few years and attracts a huge amount of public enthusiasm, as day suddenly turns into night and the temperature dips, owing to sunlight being blocked. People in India would not be able to get a feel of this Total Solar Eclipse, but India's Sun-study mission Aditya-L1 has been witnessing a round-the-clock Total Solar Eclipse, since the craft became operational earlier this year.&nbsp;

WION spoke to experts from the Indian Institute of Astrophysics to explain how Aditya-L1 can see a Total Solar Eclipse, even when there is no Eclipse taking place.&nbsp;

"The way the relatively smaller Moon blocks the Earth's view of the massive Sun, is the same as bringing a thumb in front of the eye and blocking the view of a large building that is in front. The thumb is no way comparable to the size of the building, but it is closer to the eye and blocks the large building that is at a distance" Jayant Murthy (Retd), Senior Professor from the Indian Institute of Astrophysics told WION.&nbsp;

He added that across North America, it would appear as though a disc (Moon) had covered the Sun.&nbsp;

<h2>What is Aditya-L1?&nbsp;</h2>

Aditya-L1 is India's first dedicated mission to study the Sun and its various phenomena. Launched on September 2,&nbsp;2023, the craft reached its destination on January 6, 2024. Aditya-L1 has been placed at a vantage point known as 'L1' or 'Lagrange point 1', from here it can have an unobstructed view of the Sun.&nbsp;

This vantage location in interplanetary space is situated 1.5 million (15 lakh) kilometres from earth. For context, the moon is only 4 lakh kilometres away from the earth. The Lagrange point 1 is at one percent of the Earth-Sun distance which is about 150 million kilometres.&nbsp;

<h2>Sun is visible from the ground, what is the need for a Space-based study?&nbsp;</h2>

Studies related to the Sun can be carried out from ground-based observatories, but on a given point on earth, the sun is visible during the day and is not visible at night, due to the alternating day-night cycle. &nbsp;So, an agency would require multiple stations across the earth to view and study the sun continuously.&nbsp;

Even if there are multiple observatories on the ground, each one of them would record different kinds of observations. The unique characteristics of the equipment, the dust particles that scatter the radiation, the distortion caused by the earth's atmosphere are among the factors that bring in inconsistencies in the sun-study data collected from different ground-based observatories. &nbsp;

<h2>The layers of the Sun and what a Solar Eclipse does</h2>

The Sun's Photosphere is what emits the strongest light. The &nbsp;Photosphere is then covered by the Chromosphere (which extends 1000s of kms) and finally there is the Corona (Sun's outermost layer).

"The Sun's Corona emits light, but it is million times less intense than that of the Photosphere. Therefore, it is only during a solar eclipse(when moon covers the sun's Photosphere by coming in the path between earth and Sun) that we are able to study the faint light from the Corona" Prof. Ramesh from the Indian Institute of Astrophysics, explained to WION. He added that eclipses are phenomenon that occurred once in few years and that studying the Solar Corona during the few minutes of the eclipse would be insufficient to gather any meaningful data and inferences.&nbsp;

<h2>Why is it&nbsp;important to study the Solar Corona?&nbsp;</h2>

Professor Ramesh said that the interest in studying the Solar Corona is owing to its dynamic nature and the regular eruptions from the Corona (Coronal Mass Ejections). Coronal Mass Ejection is a phenomenon when charged particles from the sun are ejected at speeds of 3000km/second. At this speed, it can reach the earth in around 15hours, he explained.

Such phenomena can affect the electronics and solar panels of satellites orbiting the earth, it can also cause geomagnetic storms that can temporarily swell up earth's atmosphere and drag satellites that are flying as low as 200km orbit. In recent years, such an incident had damaged a few dozen Starlink satellites.

When such high-speed, charged particles from the Sun reach the earth's atmosphere, the upper layers of the atmosphere act as a barrier and divert the charged particles to earth's poles, thereby causing the Northern Lights (Aurora Borealis) and Southern Lights (Aurora Australis), a dazzling display of vibrant and colorful lights. These are often seen in shades of blue-green-yellow-red in the winter night skies near the earth's north polar and south polar regions.

<h2>How does Aditya-L1 create a '24/7 Solar Eclipse'?&nbsp;</h2>

We know that the moon blocking the earth's view of the sun helps observe the faint light of the Solar Corona. However, it is possible to use technological advancements and block the bright light from the Sun, while only viewing the faint light emitted from the Corona.&nbsp;

"On the Aditya-L1 craft, we have a device known as Visible Emission Line Coronagraph (VELC), which is capable of artificially blocking the light of the Photosphere and studying the light from the Corona. This is the same as the view during a Solar eclipse" Prof Ramesh added.&nbsp;

The VELC has been contributed by the Indian Institute of Astrophysics and Prof. Ramesh is the Principal Investigator for the VELC.&nbsp;

By using the VELC, Aditya-L1 can view the Solar Corona throughout its multi-year mission at the L1 point.&nbsp;

However, it must be noted that the Aditya-L1 craft can never see the naturally-caused Solar Eclipse, like it is visible from Earth. This is because the Aditya craft sits at the L1 points, which offers an unobstructed view of the Sun. Also, it must be remembered that the L1 point is several lakh kilometres beyond the moon and the moon cannot obstruct the Aditya craft's view of the Sun.&nbsp;

From the L1 vantage point, around which the spacecraft will be circling, the VELC instrument will be able to image the sun's corona every single minute and help researchers understand the fast changes in Solar atmosphere.&nbsp;

Using a Polarimeter, we can also measure and predict which sun spots(dark regions with strong magnetic fields, where even light cannot enter) can erupt and lead to Coronal Mass ejections. in future, this could help us predict any danger to satellites around earth, assess which CMEs will reach earth and which won't.

Scientists at a leading gravitational wave observatory detected a mysterious signal with chilling origins. As per reports, the signal has its origins in the collision between a star corpse and an unknown object.

<h2>Star corpse?</h2>

Yes, star corpse, or better known as the stellar remnant of a neuron star. It is what's left when a massive star collapses, leaving behind only a dense core.&nbsp;

One of the densest objects in the universe, Neutron stars are less dense than black holes, which have gravity so strong that even light cannot escape.

The signal, which was named GW230529_181500, as per Gizmodo, travelled 650 million light-years to reach Earth. It was picked up by the LIGO-Virgo-KAGRA Collaboration, a network of observatories, last year. This was, in May 2023, just after it resumed its operations following upgrades to improve sensitivity.&nbsp;

While researchers have identified one object in the collision as likely being a neutron star, the other much object was more massive than any known neutron star, suggesting it could be a small black hole. However, the team will further scrutinise the collision to find out what it exactly is.&nbsp;

This unknown object fills the "mass gap" between the heaviest neutron stars and the lightest black holes. A paper describing the findings has been posted on the LIGO website.

In a release Jess McIver, an astronomer at the University of British Columbia and Deputy Spokesperson of the LIGO Scientific Collaboration said that the detection "reveals that there may be a higher rate of similar collisions between neutron stars and low-mass black holes than we previously thought."

As per the report, only one other merger involving an object in this mass range has been observed before, known as GW190814.

There's a lot to look forward to. The LIGO-Virgo-KAGRA Collaboration is preparing for its fourth observing run, scheduled to start on April 10, 2023, and run until February 2025. During this time, they expect to observe more than 200 gravitational wave signals.

Scientists at a leading gravitational wave observatory detected a mysterious signal with chilling origins. As per reports, the signal has its origins in the collision between a star corpse and an unknown object. Star corpse? Yes, star corpse, or better known as the stellar remnant of a neuron star. It is what's left when a massive star collapses, leaving behind only a dense core. One of the densest objects in the universe, Neutron stars are less dense than black holes, which have gravity so strong that even light cannot escape.

It was picked up by the LIGO-Virgo-KAGRA Collaboration, a network of observatories, last year. This was, in May 2023, just after it resumed its operations following upgrades to improve sensitivity. While researchers have identified one object in the collision as likely being a neutron star, the other much object was more massive than any known neutron star, suggesting it could be a small black hole. However, the team will further scrutinise the collision to find out what it exactly is. This unknown object fills the "mass gap" between the heaviest neutron stars and the lightest black holes. A paper describing the findings has been posted on the LIGO website.

As per the report, only one other merger involving an object in this mass range has been observed before, known as GW190814. There's a lot to look forward to. The LIGO-Virgo-KAGRA Collaboration is preparing for its fourth observing run, scheduled to start on April 10, 2023, and run until February 2025.

North America will witness a total solar eclipse on April 8. At least 15 states in the United States are within the path of totality. NASA has released a map showing where and when skywatchers can witness the astronomical spectacle.

North America will witness a total solar eclipse on April 8. At least 15 states in the United States are within the path of totality. NASA has released a map showing where and when skywatchers can witness the astronomical spectacle. Mexico's Pacific Coast will be the first place to witness the total eclipse at around 11:07 am PDT. It will then be visible across a swath of the US, from Texas to Maine, and into Canada. According to NASA, around 31.6 million people live in the path of totality. It is the area where the Moon fully blocks out the Sun. The width of the path is between 108 and 122 miles and an additional 150 million people live within 200 miles of the path of totality. The total solar eclipse which will start over the Pacific Ocean will cross dozens of states before it moves into Canada in southern Ontario. The eclipse will exit the North American continent around 5:16 pm NDT from Newfoundland, Canada. Moreover, the eclipse will be first visible partially at 12:06 pm CDT near Eagle Pass, Texas. Then, it will gradually move to totality around 1:27 pm CDT. Over the next few hours, it will progress along its path to the northeast. NASA has shared times for several cities in the path of totality across the United States. One can check their ZIP code on NASA's map to see when the eclipse will reach near them if they're in the path of totality. Small parts of Tennessee and Michigan will experience the total solar eclipse, with several major cities across the U.S. in its path of totality and many others seeing a partial eclipse.

A groundbreaking study in the UK has revealed that reducing the duration of MRI scans for prostate cancer by a third would make them cheaper and more accessible without compromising on their accuracy. Lower costs would mean that more men could be offered scans and diagnosis for a disease which is highly treatable in its early stages.

<h2>Current system</h2>

As of today, doctors rely on a three-stage MRI scan to detect prostate cancer. The patient is injected with a contrast dye at the third stage, which helps to enhance the images from the scan. Now, the new research indicates the third step can be done away with if the first two scans are done with high precision and good quality.

<h2>New Study</h2>

Researchers from University College London (UCL) and University College London Hospitals conducted a study in which they assessed the impact of dropping the third stage. The study involved 555 patients from 22 hospitals in 12 countries.

The results were exciting. They found that the shorter scans enabled doctors to diagnose 29 per cent of prostate cancers, the same proportion as with three-step scans.

Dr Clare Allen, lead radiologist on the trial, emphasised that significant prostate cancers were not likely to be missed if a third scan was not done.

“The scans will be quicker, cheaper and can be offered to more men,” she was quoted as saying by The Guardian. “Though it is critical to emphasise that dropping the third part of the MRI scan is dependent on the first two parts of the scan being of high quality,” she added.

<h2>Difference in cost</h2>

According to experts, the shorter scan method would be 50 per cent cheaper and also quicker. In the UK, while a three-scan MRI costs £273 on average, a two-phase scan costs just £145.

According to Matthew Hobbs, director of research at Prostate Cancer UK, which co-funded the trial with the John Black Charitable Foundation, the patients would no longer require injection.

“This will allow more men to benefit from a better, more accurate diagnosis at a lower cost to healthcare systems not only in the UK, but worldwide,” he said.

Solar Eclipse 2024: Skywatchers are eagerly waiting for a total solar eclipse set to grace the skies across North America on April 8. The astronomical spectacle will turn the day into night, turning the sky dark.

Solar Eclipse 2024: Skywatchers are eagerly waiting for a total solar eclipse set to grace the skies across North America on April 8. The astronomical spectacle will turn the day into night, turning the sky dark. However, the total eclipse will be visible only in a few locations. Solar eclipse is an astronomical phenomenon that occurs when the Moon crosses the Earth and the Sun, blocking the Sun's light either entirely or partially. When the Moon covers the Sun totally, it casts a shadow on Earth, forming the "path of totality," a relatively narrow band that moves across the surface. When the weather and clouds cooperate, people inside the band can witness a total solar eclipse. Solar Eclipse 2024: Date, Time, Visibility And Duration The total solar eclipse of 2024 will occur on April 8. It will be visible across a 185-kilometre stretch between Mexico, the United States and Canada. The total solar eclipse will not be visible in India. According to the Indian Standard Time (IST), the total solar eclipse will begin at 09:12 pm on April 8 and the totality will start at 10:08 pm. It will end on April 9 at 2:22 am IST. Mexico's Pacific coast will be the first place to experience totality at around 11:07 am PDT. Furthermore, the occurrence will leave Maine at around 1:30 pm PDT. Although the whole solar eclipse will take about two and a half hours, the totality will last only four minutes. The duration of totality i.e. four minutes and 27 seconds is almost double that of The Great American Eclipse of August 2017. ALSO READ | Google’s Solar Eclipse 2024 search animation steals the show! Here’s how to see it ... Solar Eclipse 2024: How To Watch The Sun surface produces enough light to damage individual retinal cells in your eyes, no matter how small portion you stare at. Skygazers worldwide have been advised to wear protective eyewear, like eclipse glasses, during the solar eclipse. Looking directly at the solar eclipse can burn the eye's retinas and cause permanent damage or even blindness. For people who will not be able to witness the solar eclipse in person, they can watch the solar eclipse online on NASA's live stream on YouTube. The space agency will start the live stream at 10:30 pm IST (05:00 pm GMT) and continue until 01:30 pm IST (08:00 pm GMT). McDonald Observatory in Texas will also broadcast the live streaming of the solar eclipse. (With inputs from agencies)
