Scientists have captured the most detailed images ever taken of the Sun's surface, revealing extraordinary patterns and powerful activity hidden from Earth. Using the Daniel K. Inouye Solar Telescope in Hawaii, researchers observed rare swirling structures linked to the Kelvin–Helmholtz instability.

The discovery was made while testing the telescope's advanced capabilities, surprising scientists who described the images as unlike anything they had seen before. These observations could help researchers better understand how the Sun works, its changing activity, and its impact on Earth.

Scientists Capture Unprecedented Images of Sun's Surface | Never-Before-Seen Solar Activity Revealed

A research paper by Daniel Jampolski and Professor Luciano Rezzolla from Goethe University Frankfurt suggests that it is highly possible that not every black hole we encounter is what it seems, and instead could be a gravastar. Their mathematical model, a first in this regard, shows how a collapsing star could stop right before becoming a black hole and trigger a Big Bang to birth a miniature universe inside itself. This theory also lends credence to the belief that our own universe could be sitting inside a body similar to a black hole. Their findings also solve some of the problems associated with black holes, like how something that was the size of billions of Suns can squeeze into an infinitely small point. Besides, there is the added mystery of what lies beyond the event horizon since everything that falls inside cannot be observed.<h2>Gravastar - A point right before the black hole</h2>The authors propose an ultra compact object known as a gravastar - a radically new mathematical solution to Einstein's equations of General Relativity. The paper states that in some cases, when a dead star collapses, it does not convert into a black hole. There is no singularity or an event horizon, and at the very end of its last stages, the matter is compressed to such extremes that it triggers the birth of a miniature universe inside the dying star. This newly formed universe would be almost the same as the Big Bang that gave rise to our own universe, the authors wrote in the paper. Dark energy would drive its expansion, just like our cosmos. As this mini universe pushes outwards against the inward pull of gravity, the opposing forces would stop it from becoming a black hole.

The James Webb Space Telescope (JWST) has studied a planet that is essentially a rocky planet 48 light-years away. LHS 3844 b was first discovered by the Transiting Exoplanet Survey Satellite (TESS) in 2018. It was revealed to be a tidally locked planet, meaning its one side was always facing its star. It was named Kua'kua, after a Central American Bribri word for "butterfly", and is about 30 per cent bigger than Earth. It completes one orbit of its red dwarf star host named Batsu in 11 hours. Being too close to its star means it is constantly burning at a temperature of 1000 Kelvin. That was all the information scientists had, until now.

A blast from deep space that lasted for seven hours surprised astronomers in 2025. It was a signal coming from some intensely active region. Designated GRB 250702B, it was first detected in the 1960s by the US military. However, over the years, as technology developed, instruments detected more of them. This signal intrigued scientists because of how long it lasted. Typically, these bursts can go from a few milliseconds to several minutes. The longest burst before GRB 250702B was recorded last year and was 15,000 seconds long. GRBs largely have two points of origin - Supernovae or Kilonovae.

Dr Ronaldo Laishram, a 29-year-old astrophysicist from Manipur, discovered an ancient structure in the universe and named it after the state's iconic Loktak Lake. He used data from Japan’s Subaru Telescope and NASA’s James Webb Space Telescope (JWST) to detect this giant housing young galaxies in the early universe. Laishram is a resident of Khangabok in Thoubal district&nbsp;and is a researcher at the National Astronomical Observatory of Japan (NAOJ). He completed his Master’s and PhD in Astronomy at Tohoku University in Japan, and has been working with the NAOJ since October 2024. His work is mainly focused on galaxy formation and the early universe.&nbsp;Talking about his discovery, Laishram said that this structure is a protocluster, a cosmic "nest" or "embryo" of galaxies that will eventually grow into a massive galaxy cluster. The light from it travelled 12.6 billion years, barely one billion years after the universe was formed. It is still a work in progress, with gravity building the cluster. Laishram said that his discovery throws light on galaxy formation in the early universe. Explaining what he recorded, he said that galaxies in crowded regions were acting differently from galaxies in quieter, less-populated regions. His findings show that the region in which a galaxy takes shape can affect how it grows.

Sagittarius B2 is a giant molecular cloud at the centre of our galaxy, located roughly 300 light-years from Sagittarius A*, the supermassive black hole at the centre of our galaxy. It smells like rum and tastes like raspberries, and is the Milky Way's most prolific stellar nursery. Scientists used the James Webb Space Telescope (JWST) to look past the thick dust at the galactic centre, where they came across some fascinating things.

Deadly 'cosmic cocktail' floating in Milky Way tastes like raspberries and smells like rum

Scientists have captured two planets smashing into each other, giving a rare insight into how our own planet, Earth and the Moon might have formed. The exciting event happened around Gaia20ehk, a star similar to our sun, located 11,000 light-years from Earth. The star and its planets reside near the constellation Puppis, or the "poop deck". A planetary collision has only been seen a few times in the past, but this one is different since astronomers say it is almost like seeing our own planet's history. Lead author of the study, Anastasios Tzanidakis, a doctoral candidate in astronomy at the University of Washington, said that several telescopes around the world "caught the impact in real time." He added, "There are only a few other planetary collisions of any kind on record, and none that bear so many similarities to the impact that created the Earth and moon." The study was published in The Astrophysical Journal Letters on March 11.Also Read: <a href="https://www.wionews.com/science/scientists-pin-source-of-three-mysterious-signals-from-centre-of-milky-way-to-excited-dark-matter-1772794076955">Scientists pin source of three mysterious signals coming from centre of Milky Way to…</a><h2>How did scientists know that two planets had collided?</h2>It is not like planets rarely collide with each other. In fact, every young star system is a chaotic place with debris flying all around, crashing and smashing before coalescing to form planets and moons. However, to see these events from Earth is not easy. To witness the violent cosmic episodes, the planets' orbits must take them directly in front of their home star. When this happens, their debris blocks part of the star's light, and the telescopes detect and measure it in visible and infrared light.

A collision between two planets was seen from Earth, an event that has only been seen a handful of times in the past. Scientists noticed chaos and temperatures running extremely high near the constellation Puppis, and were surprised when they found the reason.

Scientists have captured two planets smashing into each other, giving a rare insight into how our own planet, Earth and the Moon might have formed. The exciting event happened around Gaia20ehk, a star similar to our sun, located 11,000 light-years from Earth. The star and its planets reside near the constellation Puppis, or the "poop deck". A planetary collision has only been seen a few times in the past, but this one is different since astronomers say it is almost like seeing our own planet's history. Lead author of the study, Anastasios Tzanidakis, a doctoral candidate in astronomy at the University of Washington, said that several telescopes around the world "caught the impact in real time." He added, "There are only a few other planetary collisions of any kind on record, and none that bear so many similarities to the impact that created the Earth and moon." The study was published in The Astrophysical Journal Letters on March 11.

It is not like planets rarely collide with each other. In fact, every young star system is a chaotic place with debris flying all around, crashing and smashing before coalescing to form planets and moons. However, to see these events from Earth is not easy. To witness the violent cosmic episodes, the planets' orbits must take them directly in front of their home star. When this happens, their debris blocks part of the star's light, and the telescopes detect and measure it in visible and infrared light.

Chaos, heat and a star that went bonkers: Scientists see major collision between two planets

Earth is a rare cosmic body which supports life with just the right balance of ingredients and is in the optimal zone near the Sun where it is warm enough for life to thrive. Our planet has an atmosphere us from solar radiation and a magnetic field. A new study has suggested that for a planet like Earth to be born, we need a warm solar system, and this is triggered by short-lived radioisotopes (SLRs). When these isotopes decay, a warmer cosmic environment is formed. This prevents terrestrial planets like Earth from holding on to too much water. If these isotopes did not exist, those planets similar to Earth in size would turn into a theoretical type of exoplanet, called Hycean worlds. Such bodies have a deep global ocean underneath a thick, hydrogen-rich atmosphere.&nbsp;So, how do we know that our solar system had these crucial isotopes? This is proven by meteorites, as research has shown these isotopes, or SLRs, to be present in these rocks. For these short-lived radioisotopes to form, a supernova is needed, a stellar explosion leading to the death of a star. However, this powerful cosmic event would rip apart the protoplanetary disk of a young star. But the Sun's early disk remained unscathed, and we got our solar system. If a supernova is needed for a planet to form, it would mean that Earth-like planets are rare.Also Read: <a href="https://www.wionews.com/trending/earth-has-a-tail-flowing-for-millions-of-kilometres-into-space-on-its-dark-side-1765431481520">Earth has a tail, flowing for millions of kilometres into space on its dark side</a>Also Read: <a href="https://www.wionews.com/trending/catastrophe-in-2-8-days-scientists-say-earth-at-risk-of-disastrous-chain-reaction-in-space-1765868167625">Catastrophe in 2.8 days: Scientists say Earth at risk of disastrous chain reaction in space</a><h2>Earth-like worlds could be very common</h2>However, a new study states that Earth-like planets could be extremely common in the universe.

Sun-like stars form within star clusters, which means the chances of such a supernova are quite good, and hence, there might be several more Earth-like planets.&nbsp;

For Earth to be born, our solar system needed certain isotopes which could only be formed by supernovae. But, shouldn't such a stellar violent event kill a planet-forming disk? Here is what a study says about such events and how common Earth-like bodies are.

The fate of the universe has changed, and according to scientists, we won't be torn to shreds but will be compressed, falling under the pressure of gravity. A team of South Korean scientists notes in a study that the universe will likely end in the Big Crunch. This is because of dark energy that is becoming weaker, and this will hand over power to gravity, which will pull everything together. Previously, scientists believed gravity would eventually slow down the expansion of the universe. But then in 1998, they saw signs of dark energy and said that this force is speeding up the expansion of the universe. This process was assumed to rip apart atoms in the future, causing the Big Rip.&nbsp;The South Korean scientists gathered supernova data that first revealed dark energy nearly three decades ago. Prof Young Wook Lee, of Yonsei University in Seoul, and his team adjusted this information and noted a change in dark energy, and that the acceleration of the universe was slowing down. This, he says, has changed the fate of the universe. In such a scenario, where dark energy weakens, gravity would take over and pull the galaxies back together. This opens up the possibility of Big Crunch becoming very real. Professor Ofer Lahav of University College London told the BBC that with dark energy going up and down, the entire physics would be shaken up.Also Read: <a href="https://www.wionews.com/science/hubble-spots-600bn-km-wide-scaled-up-version-of-our-early-solar-system-dracula-s-chivito-shocks-scientists-1766582525866">Hubble spots 600bn km wide scaled-up version of our early solar system: Dracula’s Chivito shocks scientists</a><h2>Big Bang in reverse</h2>What will happen is a Big Bang in reverse, with the universe falling in on itself.

There would be no space or time, and all that would be left is a huge fireball.&nbsp;However, Lee's theory does not have many takers. The larger view still is that the universe is continuously expanding and dark energy remains unchanged. What would the Big Crunch look like to us? Several papers have talked about the Big Crunch, and here is what it would appear like to us on Earth. The visible stars and galaxy clusters will become closer to each other and start merging.

The universe will end someday, as it is expanding and stretching due to dark energy. But a South Korean scientist says this force is weakening, and the expansion has slowed down. Soon, gravity will become the bigger force and the universe will end in a Big Crunch.

Uranus, the seventh planet in our solar system, is often mocked for its name. However, did you know that this was not the first name it got? In fact, its initial name was deemed even more controversial. Uranus was discovered in 1781 by the German-British composer and scientist William Herschel. This ice giant is blue in colour, has faint rings and has at least 27 moons. The telescope that Herschel was using at the time of the discovery was the 40-foot Newtonian reflector telescope. Built in 1789, it was the largest, most powerful telescope in the world. King George III gave grants totalling around $5,230 at the time to build this telescope.&nbsp;&nbsp;So when Herschel discovered Uranus using this technological marvel, he thought about honouring the King. He named it somewhat on those lines. The planet was initially named "the Georgium Sidus," Latin for George's Star. Space enthusiasts and scientists weren't happy with the name, and it stirred quite a controversy. Planets were typically named based on Greek or Roman mythology. But the usual planet naming criterion was not followed in this case.

Scientists have found why Kepler-56, a red giant star, has a weird spin, and according to a new study, this is because it likely gobbled up one of the planets orbiting it. Takato Tokuno, a doctoral student in the Department of Astronomy at the University of Tokyo, studied the star's peculiar movement. The outer envelope of Kepler-56 is spinning incredibly rapidly, more than what is ideal for a red giant star. The star's core is also misaligned with its outer envelope as it spins in different directions. This could probably have been because of one of its giant planets, since they can exert a pull on their star, just like Jupiter does on the Sun. The action repeated over millions of years could lead to the outer atmosphere spinning faster.&nbsp;However, this scenario seemed unlikely in this case, since for planets to raise rides and transfer rotational energy to the star would require a very perfect and efficient setting. Tokuno then tried to analyse the possibility that the star could have eaten up the planet, causing the weird spin. This action would affect the rotation of the star. A collision would lead to the star absorbing the energy of that impact and spinning faster. Kepler-56's core and atmosphere would also become misaligned if the strike happens at an odd angle.Also Read: <a href="https://www.wionews.com/trending/2300-foot-newly-discovered-killer-twilight-asteroid-near-sun-could-kill-billions-1764224226975">2,300ft newly discovered killer 'twilight' asteroid near the Sun could kill billions</a><h2>What was the planet that was eaten up by Kepler-56 like?&nbsp;</h2>In the paper, Tokuno suggests that a planet that would have become Kepler-56's meal would have weighed somewhere between half the mass of Jupiter and twice its mass and had an orbital period of between one and six days. This is what typical "hot Jupiter" exoplanets are like that ultimately meet a similar fate. However, it is also possible that the star was born with a high spin rate. But that wouldn't explain the misalignment between the core and the atmosphere. And even if we assume that it was born this way, the fast spin would again only be explained by the likelihood that it ate a planet while it was still young.

Long ago, when humans were only just beginning to emerge, Earth might have been pounded by comets, an event possibly triggered by a passing star. This star was nowhere near our planet, and in fact, brushed past the Oort cloud about 2.5 million years ago. But this event stirred up the Oort Cloud, pushing out comets from this region like bullets, which then rained down on Earth. This has been proposed in a new study that will be published in the Nature journal. Researchers wrote that the nearby star HD7977 skimmed past the solar system right about the time humans were taking their place on Earth. This would have had an effect on the life on our planet. “When a star passes through the outskirts of the Solar system, it can gravitationally kick Oort cloud comets towards Earth and generate a major meteor shower that would significantly affect terrestrial life,” author Avi Loeb wrote.Also Read: <a href="https://www.wionews.com/trending/rogue-giant-eight-times-bigger-than-jupiter-crashed-the-solar-party-making-some-planets-wonky-1763118236308">Rogue giant eight times bigger than Jupiter crashed the solar party, making some planets wonky</a>&nbsp;<h2>What is Oort Cloud?</h2>“Our calculations showed that this star passage likely repopulated the Inner Oort Cloud and potentially triggered a significant comet shower on Earth,” he added.

It pointed the Very Large Telescope (VLT) in Chile at supernova SN 2024ggi in April 2024 and saw an astonishing view for the very first time. Supernovas are nothing but a cosmic occurrence that happens after a star dies. While the star’s surface was undergoing an agonising end, ESA saw the shape of a supernova at its earliest, ephemeral stage. The finding was published in Science Advances on November 12. Yi Yang, an astronomer at Tsinghua University and co-author of the study, said in a statement, "The geometry of a supernova explosion provides fundamental information on stellar evolution and the physical processes leading to these cosmic fireworks."&nbsp;The paper states that the initial blast rendered an olive shape. When the material propagated outward and interacted with matter around the star, it flattened while maintaining the same axis of symmetry. What they saw wasn't exactly a colour-filled blast, but a reconstruction of its geometry from the polarisation of its light.&nbsp;Supernovas happen when a massive star, one much bigger than the Sun, runs out of fuel and eventually dies. Its core collapses and its outer mass falls inward. It then bounces outwards, releasing a huge amount of energy, which is what makes the supernova appear extremely bright. This "bounce shock" has remained a puzzle for decades, Yang wrote in the study. Supernova SN 2024ggi is located in the galaxy NGC 3621, 22 million light-years away. It was so massive that before turning into a supernova, it was a red supergiant star with a mass that was 12 to 15 times that of the Sun and a radius 500 times larger.&nbsp;Scientists at ESO were able to capture the short-lived “breakout” shape using a technique called spectropolarimetry. Lifan Wang, co-author of the study and an astronomer at Texas A&amp;M University, said, "The technique delivers information about the geometry of the explosion that other types of observation cannot provide."&nbsp; &nbsp;

The Very Large Telescope (VLT) in Chile saw the first moments of supernova SN 2024ggi 22 million light-years away. This helped them deduce what a supernova looks like right when it is first formed.

A team of astronomers at Yonsei University has found that the universe has slowed down. It is not expanding at a fast pace any more as hypothesised by scientists. This means that dark energy has weakened. So what is really going on in the universe?

Scientists are shocked to see a planet chowing on six billion tons of gas and dust each second, an event that has been going on for a couple of months. The so-called rogue planet is witnessing an extreme and unprecedented "growth spurt", proving that planets are not docile cosmic objects. The new observations were made by the European Southern Observatory's Very Large Telescope (ESO's VLT). This free-floating planet is eating up gas and dust from its surroundings at an astounding rate, providing new insights into the formation of planets. Cha 1107-7626 is around five to 10 times the mass of Jupiter, and lives 620 light-years away in the constellation of Chamaeleon. The planet is being fed by a circumplanetary disk of gas and dust, which constantly falls into it. The process, known as accretion, witnessed a sudden acceleration by August 2025 in Cha 1107-7626. It sped up by eight times within a few months, leading it to its current rate of six billion tons per second. The discovery was published today in the Astrophysical Journal Letters.&nbsp;This planet is still forming, giving scientists a peek into how such large bodies develop. "We’ve caught this newborn rogue planet in the act of gobbling up stuff at a furious pace,” said Johns Hopkins University’s Professor Ray Jayawardhana. Lead author of the study, &nbsp;Víctor Almendros-Abad, said that this discovery proves that "planets are not quiet and stable worlds". An astronomer at the Astronomical Observatory of Palermo and National Institute for Astrophysics (INAF), Italy, Almendros-Abad added, “This is the strongest accretion episode ever recorded for a planetary-mass object."Also Read: <a href="https://www.wionews.com/science/is-nasa-nuking-an-asteroid-real-life-armageddon-could-happen-by-2031-details-1759238690934">Is NASA nuking an asteroid?

As pointed out above, the researchers noted that the speed of gulping down material changed vastly over a few months.

"The origin of rogue planets remains an open question: are they the lowest-mass objects formed like stars, or giant planets ejected from their birth systems?" co-author Aleks Scholz, an astronomer at the University of St Andrews, United Kingdom, said. The findings prove that some rogue planets are formed in a similar manner as stars, since both witness bursts of accretion.&nbsp;“This discovery blurs the line between stars and planets and gives us a sneak peek into the earliest formation periods of rogue planets,” said Dr Belinda Damian, an astronomer at the University of St Andrews. Another thing that stumped researchers was the presence of water vapour in the disk around the planet during the accretion episode, but not after it. This phenomenon had been spotted in stars but never in a planet. “We’re struck by quite how much the infancy of free-floating planetary-mass objects resembles that of stars like the Sun,” Professor Jayawardhana said.&nbsp; &nbsp;

A planet located 620 light-years away in the constellation Chamaeleon is acting like a young star, chomping down on matter at the rate of six billion tons per second. Scientists are amazed to see the infant planet going through such a growth spurt.

The discovery of an Einstein Cross stunned scientists who spotted an anomaly. An Einstein Cross has four images at straight angles, but this one had a fifth image at the centre. What was it? Researchers think it is a dark matter halo. 

Einstein Cross, a cosmic wonder of space-time bending - What's hiding in this new discovery?

A team of international scientists has discovered a rare cosmic formation which has never been seen before. Only about a dozen Einstein Crosses have been found in the universe to date. This makes them rare, yet the latest discovery makes them even more intriguing. An Einstein Cross only has four images. But this one has an extra image in the middle. Researchers at Rutgers University were shocked when a French astronomer sent them the photo. Pierre Cox, a French astronomer, Research Director at the French National Centre for Scientific Research and the study's lead author, first spotted the anomaly.

The universe as we know it was only discovered 100 years ago. Before that, scientists thought that the Milky Way was the entire universe. But one observation by Edwin Hubble changed that forever, introducing us to a world where our galaxy was almost negligible.
