<p>The Parker Solar Probe is the latest man-made spacecraft to observe 3I/ATLAS. The WISPR instrument on board the NASA probe took photos of the comet from October 18 to November 5. Members of the WISPR team said in a statement, “Parker Solar Probe snapped around 10 images of the comet per day." They added that during this time, Parker was speeding away from the Sun after undertaking its 25th solar flyby on September 15. At this time, the solar probe was at a point from where it spotted 3I/ATLAS going behind the Sun. “At the time, the comet was near its closest point to the Sun, at a distance of about 209 million km (130 million miles), placing it just outside the orbit of Mars," the Parker probe team added. Notably, the comet reached perihelion on October 29.</p><p>&nbsp;</p>

<p>This observation is one of its kind since 3I/ATLAS had become invisible from Earth as it sped towards the sun. The glare of our star hid it from us, and none of the telescopes could see it. But this is right when Parker saw it, revealing what was going on with the comet. "The images offer a valuable look at the comet over a period when it couldn’t be seen from Earth because it appeared too close to the Sun from Earth’s perspective," the team said.</p><h2><strong>3I/ATLAS image near Sun captured by Parker</strong></h2><p>Notably, some scientists, who have been claiming that 3I/ATLAS could be an extraterrestrial probe sent by intelligent beings, had proposed that the object might use its time behind the Sun to slingshot itself using its gravity towards Earth. This is because it was practically invisible for days. However, thanks to Parker, we now have pictures of the comet from its time behind the Sun. The WISPR team is currently processing these images to remove stray sunlight and compensate for exposure times. It also appears to change brightness because of the difference in exposure times, the researchers added. Once the images are processed, the Parker team hopes to get a better insight into 3I/ATLAS.</p>

3I/ATLAS latest update: The Parker Solar Probe saw the interstellar comet racing behind the Sun. It took photos of 3I/ATLAS at a time when it had become invisible from Earth because of the glare from the Sun. The images are being processed to get a better look at the comet.

<p>Indian space agency ISRO has commenced the 24-hour countdown to the Wednesday, (24th Dec) launch of US firm AST SpaceMobile's BlueBird-6 satellite aboard the LVM3 rocket. The three-stage LVM3 rocket, India's most capable spacefaring vehicle is to liftoff from the second launchpad of the Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh at 8:54am Indian Time, Wednesday. The satellite would be injected into orbit 520kms above the Earth, barely 16 minutes after launch.&nbsp;</p>

<p>The countdown to a rocket launch involves sequential tasks like fueling, system checks, and approvals, synchronizing hundreds of people and automated systems. It's a crucial operational checklist during which all processes are validated.</p><p>&nbsp;</p><p>The 6,100kg BlueBird 6 satellite is the heaviest payload to be lifted by the LVM3 vehicle in its operational history. Therefore, this satellite would be the heaviest payload to be carried by an Indian rocket. LVM3 has a track record of having delivered success in all its eight missions to date.</p><p>&nbsp;</p><p>This mission is being executed as part of a commercial deal between ISRO's business arm NewSpace India Limited(NSIL) and the Texas-based AST SpaceMobile. As a launch services provider(rocket builder and operator), ISRO launches foreign-origin satellites to space on a commercial basis. Facilitated by NSIL, these commercial space missions are like a taxi ferrying a passenger. In this case, the passenger is the US firm, which pays the Indian Government for the launch service.</p><p>&nbsp;</p><p>This is the third commercial mission of LVM3, and the first time that the Indian LVM3 rocket is executing the mission for an American customer. Earlier, it had executed two launches for a European customer OneWeb(now Eutelsat OneWeb).</p><h2><strong>About AST SpaceMobile and their internet-beaming satellites</strong></h2><p>AST SpaceMobile is a Texas-based telecom company that aims to build and launch a fleet of satellites that can directly provide internet connectivity to mobile phones. Typically, only purpose-built satellite phones can facilitate satellite communication. These traditional satellite phone handsets are bulky and require visible antennas, they offer voice connectivity, and low-bandwidth texting and data services. Such services are offered by firms such as Iridium, Thuraya, among others. They are widely used in the defence and maritime sectors for providing connectivity where no communication infrastructure exists.</p><p>&nbsp;</p><p>Firms like AST and Starlink are attempting to change this by ensuring direct connectivity between smartphones and satellites. They intend to ensure that Android and Apple devices available in the market can communicate directly with satellites, without any modifications or special hardware. Thanks to the global coverage planned using a fleet of satellites, such services would eventually enable cell phone connectivity almost anywhere on Earth. In simple terms, one need not worry about being "not reachable" or "out of coverage area".</p><p>&nbsp;</p><p>As per reports, AST presently has a fleet of five first-generation (Block-1) satellites in orbit. The firm plans to launch a fleet of 45-60 second-generation (Block-2)satellites to offer services in major global regions, it is said.</p><p>&nbsp;</p><p>The firm has announced that they have a series of satellites that will be launching in the coming months. BlueBird 7 has shipped to the Cape Canaveral, Florida launch site this month, BlueBirds 8-16 are in various stages of production, with launches planned every 1-2 months on average during 2025 and 2026, the firm announced.</p><p>&nbsp;</p><p>They expect to have 45-60 satellites in orbit by year-end 2026. It is touted that these BlueBird satellites(by size) will be the largest commercial satellites ever deployed in Low Earth orbit (about 600kms above earth). Each of these satellites would carry a 2,400sq feet phased array antenna with true direct-to-cell broadband, with a claimed capability of up to 10,000 MHz of processing bandwidth and claimed peak speeds of 120 Mbps per cell.</p><p>&nbsp;</p><p>The firm says they have partnered with 50+ mobile network operators serving nearly 3 billion subscribers, "supported by a flexible spectrum strategy blending our own licensed spectrum with partner spectrum".</p><p>&nbsp;</p><p>While the launch of Bluebird-6 is being carried out from India, it must be noted that such direct-to-mobile satellite internet services have not been approved by the Indian Government. Firms like Starlink and Eutelsat OneWeb that are also into providing LEO satellite-based high-speed internet connectivity are in the process of seeking approvals from various departments of the Indian government.</p><p><br>&nbsp;</p>

In this scenario, when the third black hole enters the scene, one of them is kicked out. van Dokkum thinks the first reason is more likely in the case of this runaway supermassive black hole.

<p>A supermassive black hole has been spotted in the universe, zooming at an unbelievable speed of 1,000km/second. It comes from the Owl galaxy, and scientists are trying to understand why it was kicked out and the reason for its mind-blowing speed.&nbsp;</p>

<p>The Chinese Kinetica rocket was launched on December 9, 2025, by the Guangzhou-based space company CAS Space from the Jiuquan Satellite Launch Centre in the Gobi Desert. It carries six Chinese multifunctional satellites. “Our team is currently in contact for more details,” CAS Space tweeted. It asserted that all CAS space rockets use their launch window system with ground-based cooperation to avoid collision with space debris and other space objects. It also agreed with Nicholis for further collaboration to avoid orbital collisions. “This calls for re-establishing collaborations between the two New Space ecosystems,” wrote the CAS Space in a follow-up.&nbsp;</p><h2>Clusters of satellites are a ticking time bomb</h2><p>There are roughly 13,000 functioning satellites present in the Earth's orbit; among them, SpaceX alone has close to 9,300 satellites, almost ⅓ of which were launched in 2025. According to a Harvard Astrophysicist, Jonathan McDowell, there is at least one or two satellites that collapse every day. &nbsp;Nearly 54,000 space objects with a size of four inches remain as space debris in orbit, whereas nearly 140 million other pieces measuring between 0.04 inches and 0.39 inches are available in space. According to Leo Labs, this is a ticking time bomb. At any moment, just a single collision could set off a chain reaction dubbed the Kessler syndrome, potentially rendering orbits unusable for satellites and space travel for generations.</p>

A SpaceX Starlink satellite narrowly avoided a collision with China’s Kinetica-1 rocket, coming within 200 metres in low Earth orbit. The incident has reignited concerns over space debris, satellite congestion, and the risk of a catastrophic Kessler syndrome.

<p>Mosasaurs, an extinct group of aquatic squamate reptiles, adapted to a very different environment during the Late Cretaceous period, as discovered by a group of scientists. These marine predators have been known to hunt in the salty oceans, but now they have found that these mammoths adapted to a freshwater environment and even fed on dinosaurs. IFL Science reported that when Trissa Ford came across a Tyrannosaurus rex tooth in Hell Creek, North Dakota, in 2022, the careful digging led the group to another tooth. Dig leader Dr Clint Boyd knew it didn't belong to a T. rex, and reached out to marine reptile expert Dr Nathan Van Vranken of Eastern West Virginia Community and Technical College. He confirmed that it had come from a mosasaur of the Prognathodontini subfamily.</p><p>&nbsp;</p><p>This was strange since Hill Creek had never had an ocean, nor a salty lake. Hell Creek is almost 2,000 kilometres from the ocean, and &nbsp;Dr Melanie During, of Uppsala University, who helped the team solve the mystery, says the tooth had remained in the same place. There had also never been any saltwater source in the region. Her analysis revealed that this mosasaur was a descendant of a species that had adapted to living in river water. The study is published in BMC Zoology.</p><p>Also Read: <a href="https://www.wionews.com/science/this-giant-blue-dragon-monster-haunted-prehistoric-waters-of-the-pacific-ocean-72-million-years-ago-669185"><strong>A giant blue dragon mosasaur roamed the Pacific waters 72 million years ago</strong></a></p><h2><strong>Mosasaurs adapted to live in rivers</strong></h2><p>Scientists have always believed that mosasaurs lived in salty waters.

Mosasaurs underwent a major lifestyle change during the late Cretaceous period and adapted to living in a completely new environment. Researchers found a tooth that led them to find something shocking about these giants.

Mosasaurs, an extinct group of aquatic squamate reptiles, adapted to a very different environment during the Late Cretaceous period, as discovered by a group of scientists. These marine predators have been known to hunt in the salty oceans, but now they have found that these mammoths adapted to a freshwater environment and even fed on dinosaurs. IFL Science reported that when Trissa Ford came across a Tyrannosaurus rex tooth in Hell Creek, North Dakota, in 2022, the careful digging led the group to another tooth. Dig leader Dr Clint Boyd knew it didn't belong to a T. rex, and reached out to marine reptile expert Dr Nathan Van Vranken of Eastern West Virginia Community and Technical College. He confirmed that it had come from a mosasaur of the Prognathodontini subfamily. This was strange since Hill Creek had never had an ocean, nor a salty lake. Hell Creek is almost 2,000 kilometres from the ocean, and Dr Melanie During, of Uppsala University, who helped the team solve the mystery, says the tooth had remained in the same place. There had also never been any saltwater source in the region. Her analysis revealed that this mosasaur was a descendant of a species that had adapted to living in river water. The study is published in BMC Zoology.

T. rex tooth leads scientists to make a shocking discovery about brute that ate dinosaurs

<p>The current satellite mega-constellation system can crumble within days in case of an intense solar storm, according to a new paper.

<p>In a rare celestial event, the skywatcher will observe the longest Solar eclipse of the last century in August, 2027. The solar eclipse will last for 6 minutes and 23 seconds, and at its peak, the moon will completely cover the sun, daylight will fade, temperatures will drop, stars or planets will become visible as if in twilight, and the whole world will plunge into darkness. This eclipse is a once-in-a-lifetime occurrence for this generation. It is rarer because the distance between the Earth will be closest to the moon, making it possible for the moon to cover the sun for the longest time.&nbsp;</p><h2>When and where will it be visible?</h2><p>During the solar eclipse, the moon will cast a dark shadow on the Earth, which is called the umbra. This Umbra is a narrow strip of land that rapidly moves across the Earth's surface as it rotates. The path along which the umbra moves is called the path of totality. It is usually 100-200 km long. Within the area of the path of totality, day becomes completely dark, and planets and stars can be seen. For this solar eclipse on August 2, 2027, the path of totality will pass through parts of Southern Europe, such as Spain, Portugal, parts of North Africa, Egypt, Morocco, Algeria, Libya and parts of the Middle East like Saudi Arabia, before reaching Sanaa, Yemen. After crossing the Gulf of Aden, totality passes Somalia and then the northern reefs of the Chagos Archipelago in the Indian Ocean. To the rest of the world, it will be partially visible.&nbsp;</p><h2>Will it be visible in India?</h2><p>No, the path of totality will not move through India, hence the Solar eclipse will not be completely visible. It will be visible partially across the Western region, such as Gujarat, Maharashtra, between 15:34 IST and 17:53 IST.</p><h2>Viewing tips</h2><p>Viewers should use proper safety equipment, like UV glasses, because the rare phenomenon might be dangerous for the naked eye and might cause irreversible damage.&nbsp;</p>

The longest solar eclipse in a century will occur in 2027, lasting over 6 minutes. Know the date, where it will be visible and whether India can see it.

The solar eclipse will last for 6 minutes and 23 seconds, and at its peak, the moon will completely cover the sun, daylight will fade, temperatures will drop, stars or planets will become visible as if in twilight, and the whole world will plunge into darkness. This eclipse is a once-in-a-lifetime occurrence for this generation. It is rarer because the distance between the Earth will be closest to the moon, making it possible for the moon to cover the sun for the longest time. When and where will it be visible? During the solar eclipse, the moon will cast a dark shadow on the Earth, which is called the umbra. This Umbra is a narrow strip of land that rapidly moves across the Earth's surface as it rotates. The path along which the umbra moves is called the path of totality. It is usually 100-200 km long. Within the area of the path of totality, day becomes completely dark, and planets and stars can be seen. For this solar eclipse on August 2, 2027, the path of totality will pass through parts of Southern Europe, such as Spain, Portugal, parts of North Africa, Egypt, Morocco, Algeria, Libya and parts of the Middle East like Saudi Arabia, before reaching Sanaa, Yemen. After crossing the Gulf of Aden, totality passes Somalia and then the northern reefs of the Chagos Archipelago in the Indian Ocean. To the rest of the world, it will be partially visible. Will it be visible in India? No, the path of totality will not move through India, hence the Solar eclipse will not be completely visible. It will be visible partially across the Western region, such as Gujarat, Maharashtra, between 15:34 IST and 17:53 IST. Viewing tips Viewers should use proper safety equipment, like UV glasses, because the rare phenomenon might be dangerous for the naked eye and might cause irreversible damage.

Rare 2027 solar eclipse to last over 6 minutes, longest in a century: Will India see it?

<p>An Italian photographer, Valter Binotto, captured two extremely rare upper-atmosphere electrical phenomena simultaneously, at the town of Possagno, near Venice, Italy. These atmospheric phenomena are called Red Sprites and ELVE. A couple of weeks ago, an exceptionally powerful lightning strike over the Adriatic Sea between the Italian and Balkan Peninsula, the electric field formed spread over the atmosphere for hundreds of kilometres.&nbsp;</p>

<h2>What are Red Sprite and ELVE</h2><p>Red Sprite is a transient luminous event that occurs above thunderstorms. These are triggered following a powerful lightning strike and appear like a red flash with tendrils stretching downward, often appearing like a floating jellyfish in the sky. Similarly, the ELVE (Emission of Light and Very Low-Frequency Perturbations due to Electromagnetic Pulse Sources) is also triggered by electromagnetic energy from an intense lightning strike. These appear like thin glowing disks which appear in the higher ionosphere. The colour of both of these is red because of the excitation of nitrogen particles.</p><p>These are extremely rare, the latter more than the former. Capturing them is a daunting task; it requires cameras with a telephoto lens up to 300 mm, an aperture of 1.3, a high frame rate and a tripod. The photographer requires extreme patience and dedication. Valter Binotto captured both of them together.&nbsp;</p><p>“Since I started more than 10 years ago, I have photographed hundreds of sprites. ELVEs, on the other hand, only three — including this one, which is a double event of sprites and ELVEs. ELVEs are very rare and therefore more difficult to photograph,” said Valter Binotto. Valter Binotto is an award-winning wildlife photographer, but he is fond of capturing atmospheric phenomena.</p><p>&nbsp;</p>

A spectacular photograph captures two rare atmospheric phenomena red sprites and an ELVE, occurring simultaneously after a powerful lightning strike.

An Italian photographer, Valter Binotto, captured two extremely rare upper-atmosphere electrical phenomena simultaneously, at the town of Possagno, near Venice, Italy. These atmospheric phenomena are called Red Sprites and ELVE. A couple of weeks ago, an exceptionally powerful lightning strike over the Adriatic Sea between the Italian and Balkan Peninsula, the electric field formed spread over the atmosphere for hundreds of kilometres.

<p>The James Webb Space Telescope (JWST) has discovered a "hot Jupiter" planet with two long tails made of helium. For a planet to sport such tails is strange, and it is the first time that the gases leaking from an exoplanet have been studied during one of its complete orbits. This planet, named WASP-121b, also known as "Tylos," is located around 858 light-years away. Earlier observations have shown that it is an "ultrahot Jupiter." WASP-121b is a gas giant planet that orbits extremely close to its star and completes an orbit in only 30 hours.

<p>Rocket Lab's partially reusable rocket Neutron has completed final qualification tests. With this, the company is gearing up to compete with SpaceX's Falcon 9. It is its newest launch vehicle, which is expected to fly for the first time early next year. With Neutron, the company has taken a new approach to launch vehicle reusability, with its fairing opening and closing like a clamshell, releasing the vehicle's entire second stage and payload. It is a Hungry-Hippo-style fairing, acting exactly like the popular board game. Rocket Lab's workhorse Electron rocket has already gained a hold in the small launch market. SpaceX has its own recovery and refurbishment plans with Falcon, with its booster stage carrying the second stage and payload to a point where the second stage accelerates the payload to its target orbit.

<p>Rocket Lab calls Neutron "the world’s largest carbon composite launch vehicle", adding that it underwent extensive tests. To be able to pass the tests, it had to withstand external forces as extreme as 275,000 pounds, and a rapid cycling of its open and close functions to check the durability of its motors. After it is attached to the first stage, Rocket Lab will perform a series of prelaunch tests, such as a static hotfire of the nine Archimedes engines. "A rocket like Neutron has never been built before, and we're doing it at a pace and price point that's going to bring the innovation and competition needed in today's industry," Rocket Lab Neutron VP Shaun D'Mello said in a December 8 statement.</p>

Rocket Lab has completed final qualification tests on Neutron, its partially reusable rocket that can compete with SpaceX's Falcon 9 someday. Its first stage opens like a giant jaw, releasing the second stage, after which it closes and falls back.

The team reported discovering baked earth alongside what appears to be the earliest Stone Age lighter – a flint struck against pyrite, or fool's gold, to produce a spark. What is hidden beneath Barnham Forest Hidden beneath the canopy of Barnham Forest lies an archaeological gem, buried just a few metres below the Earth and dating back to the furthest depths of human pre-history, according to a report by the BBC. Around a small clearing, lush green branches seem to part like a curtain, slowly unveiling a forgotten chapter of the forest’s history. Archaeologists at East Farm Barnham in Suffolk have uncovered a prehistoric fireplace at the centre of what may have been a Stone Age “town hall,” where early humans gathered hundreds of thousands of years ago. The central hearth suggests this could have been a key site for the development of early language and social interaction. Excavations by Prof Nick Ashton and his team revealed flint tools altered by heat and layers of clay deposited after Britain’s last major ice age. The most significant find was fragments of iron pyrite—fool’s gold—used to spark fire, marking a pivotal moment in human innovation.
