Astronomers at the University of Galway discovered a new planet-forming site using ESO's VLT.
The planet is likely a gas giant with a mass many times that of Jupiter.
Stunning images show a structured disk around a young star, extending 130 astronomical units.
Astronomers used the European Southern Observatory's Very Large Telescope (ESO's VLT) in Chile to discover a new site of a new planet in formation, which is most likely a gas giant planet, according to findings published in the journal Astronomy & Astrophysics. According to the team of astronomers, led by the University of Galway, the planet is many times the mass of Jupiter.
The astronomers took stunning images of a distant young star for the first time. The pictures were captured in the form of scattered near-infrared light, which revealed a structured disk. The European Southern Observatory (ESO) published a stunning view of the new planet-forming disk as its picture of the week on Monday (June 9).
The disc was seen extended to 130 astronomical units from its parent star. A bright ring and a gap at the centre, roughly 50 astronomical units, were also seen in the images. For comparison, one astronomical unit is the approximate mean distance between Earth and the sun. It's about 93 million miles. Meanwhile, Neptune, which is the outermost planet in our solar system, has an orbital distance from the sun of 30 astronomical units.
"While our team has now observed close to 100 possible planet-forming discs around nearby stars, this image is something special," said Dr Christian Ginski, who led the study.
"One rarely finds a system with both rings and spiral arms in a configuration that almost perfectly fits the predictions of how a forming planet is supposed to shape its parent disk according to theoretical models," said Dr Ginski who is from the Centre for Astronomy in the School of Natural Sciences at University of Galway.
"Detections like this bring us one step closer to understand how planets form in general and how our solar system might have formed in the distant past," Ginski further added.
Team hopes to take an actual image
The astronomers now hope to be able to take an actual image of the young planet using the sensitivity of the James Webb Space Telescope (JWST). Researchers will be able to study the planet-disk interaction if planets in the disk are confirmed.
Chloe Lawlor, Ph.D. student in Physics with a specialisation in Astrophysics, University of Galway, said, "Working with Dr. Christian Ginski on the 2MASS1612 paper has been an incredible experience. As an early-career researcher, having the opportunity to contribute to such exciting work has been especially rewarding. This work has been the perfect introduction to scientific writing and collaboration, and I'm very grateful for this kick-start to my research career."

James Webb Telescope captures tiny galaxies that reveal big secret
Using data from NASA's James Webb Space Telescope (JWST), astronomers have identified dozens of small, starburst galaxies that played a pivotal role in transforming the early universe during a period known as cosmic tiny galaxies, though small in size, emitted powerful ultraviolet light that helped clear the fog of neutral hydrogen gas enveloping the universe's first billion years, enabling the universe to become transparent and evolve into its current discovery, presented by Isak Wold, an assistant research scientist at Catholic University of America and Nasa's Goddard Space Flight Center, was made possible by the unprecedented sensitivity of JWST's instruments, particularly the Near-Infrared Camera (NIRCam) and Near-Infrared Spectrograph (NIRSpec). The team analysed images from the UNCOVER observing program, which focused on the massive galaxy cluster Abell 2744, also known as Pandora's cluster. This cluster's immense gravity acts as a natural lens, magnifying distant galaxies and extending Webb's observational reach about 4 billion light-years galaxies identified date back to when the universe was roughly 800 million years old, an epoch astronomers call redshift this time, vigorous star formation episodes—starbursts—occurred in these low-mass galaxies, producing intense ultraviolet radiation. This radiation ionised the surrounding hydrogen gas by stripping electrons from atoms, a process essential for the universe's transition from opaque to researchers detected a distinctive green emission line from doubly ionised oxygen, originally visible light stretched into the infrared spectrum due to cosmic expansion, confirming the presence of these energetic processes. The project mapped a giant galaxy cluster known as Abell 2744, nicknamed Pandora's cluster. (Photo: Nasa) 'These galaxies punch well above their weight,' said Wold. To build a galaxy with the stellar mass of our Milky Way, one would need between 2,000 and 200,000 of these small galaxies. Yet, their abundance and ultraviolet output are sufficient to account for the entire reionisation process, assuming they release ultraviolet light at efficiencies similar to comparable galaxies in the present finding sheds light on a longstanding cosmic mystery about what powered reionisation, emphasising the outsised role of small, star-forming galaxies in shaping the universe's early James Webb Space Telescope continues to revolutionise our understanding of cosmic history by revealing the building blocks of galaxies from the dawn of timeMust Watch

Trump plan to kill dozens of NASA missions threatens US space supremacy
NASA 's car-sized Perseverance rover has been roaming the surface of Mars for four years, drilling into the alien soil to collect dirt it places in tubes and leaves on the ground. Engineers designed Perseverance to be the first step in the agency's exploration of the Red Planet. In the future, more robotic spacecraft would arrive to sweep up the capsules and rocket them back to Earth, where scientists could look for signs that Mars once was, or is, a world with life. The wait for answers may be about to get longer. President Donald Trump 's proposed 2026 budget for the US National Aeronautics and Space Administration would cancel the planned follow-on mission, potentially abandoning the tubes for decades to Martian dust storms. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like New Container Houses Vietnam (Prices May Surprise You) Container House | Search ads Search Now Undo The White House is calling for a roughly 50% cut to NASA's science spending to $3.9 billion, part of an overall pullback that would deliver the lowest funding level in the agency's history and kill more more than 40 NASA science missions and projects, according to detailed plans released last month. The Trump administration has also left the agency without a permanent leader and without a vision for how America's civilian space policy is going to work with US allies and compete with China and other rivals. The cuts would follow a shift in how the American public thinks about space. NASA has long enjoyed a unique place in US culture, with its exploits celebrated by movies, theme parks and merchandise — but companies like Elon Musk's SpaceX have begun to capture more attention. Live Events For decades, NASA's scientific undertakings have provided critical groundwork for researchers seeking to understand the structure of the universe, study how planets form and hunt for evidence that life might exist beyond Earth. Pictures from NASA craft like the Hubble Space Telescope and the recently launched James Webb Space Telescope have inspired and delighted millions. Now, the agency's position at the vanguard of discovery is facing foreclosure. Among the other programs set to lose funding are a craft already on its way to rendezvous with an asteroid that's expected to pass close to Earth in 2029, and multiple efforts to map and explore the acidic clouds of Venus. Researchers worry that abandoning missions would mean investments made by earlier generations might be lost or forgotten. 'Once you launch and you're operating, then all those costs are behind you, and it's relatively inexpensive to just keep the missions going,' said Amanda Hendrix, the chief executive officer of the Planetary Science Institute, a nonprofit research organization. 'So I'm very concerned about these operating missions that are still producing excellent and really important science data.' The Trump administration's narrower vision for NASA comes as it is seeking to reduce waste and jobs in the US government. Critics have faulted NASA over sluggish management of key programs, spiraling costs and delays. Still, the administration is eager to pour more money into putting people in space. It wants to use $7 billion of the $18.8 billion it would allocate to NASA overall to ramp up efforts to return people to the moon, and invest $1 billion more in sending people to Mars. 'This is a NASA that would be primarily human spaceflight focused,' Casey Dreier, chief of space policy for The Planetary Society, a nonprofit that advocates for space science and exploration, said of the proposed changes. 'This is a NASA that would say, 'The universe is primarily the moon and Mars,' and basically step away from everything else.' There are signs that the administration's proposed cutbacks won't satisfy lawmakers who view space as vital to US interests. Senator Ted Cruz, the Texas Republican who leads a committee that oversees NASA, has proposed legislation that would would provide nearly $10 billion to the agency. 'American dominance in space is a national security imperative,' Cruz said in a statement to Bloomberg. 'The Commerce Committee's bill carefully invests in beating China to the Moon and Mars — while respecting every taxpayer dollar. It's rocket fuel for the commercial space companies and NASA that are working to keep America ahead of China in the Space Race.' As Trump's spending proposal moves through Congress, NASA has been left without a strong leader who can press its case after the president withdrew his nomination of billionaire commercial astronaut Jared Isaacman to run the agency. In a recent interview on the All-In Podcast, Isaacman appeared to suggest Trump pulled his nomination because of his close ties to Musk, who had a public falling out with the president. Trump threatened to cancel SpaceX's government contracts amid the row, but has since backed down. 'Stopping Jared from becoming confirmed is only going to hurt NASA's ability to push back on budget cuts,' Jim Muncy, a space consultant and lobbyist with PoliSpace, said before Isaacman's nomination was pulled. Spaceflight Shift For decades, NASA handled every step of launching rockets, probes and people into space, from developing, building and launching vehicles, to running missions. Only the government had the resources and the capacity to shoulder the risks without returning a profit. That all changed in recent years with the emergence of a vibrant US space industry dominated by wealthy entrepreneurs with a passion for spaceflight and the financial wherewithal to withstand repeated failure. Over time, NASA has ceded more design, development and production work to those companies. SpaceX is carrying cargo and astronauts to the International Space Station, and sending probes into deep space from a rented launchpad at NASA's Kennedy Space Center. After helping to spur the development of SpaceX hardware, NASA is now one of the company's biggest customers. 'This has kind of been the tension with the rise of commercial space,' said Mike French, a consultant for the Space Policy Group . 'NASA has gone from 'We're operating these things; we're building these things' to 'We've gotten really good at buying these things.'' During Trump's presidency, NASA's transformation into an incubator for private industry is likely to gain speed. Throughout its budget proposal, the White House calls for mimicking past programs that have leaned more on outsourcing to the private sector. 'With a leaner budget across all of government, we are all taking a closer look at how we work, where we invest, and how we adjust our methods to accomplish our mission,' NASA's acting administrator, Janet Petro, wrote in a message accompanying the plan. 'At NASA, that means placing a renewed emphasis on human spaceflight, increasing investments in a sustainable plan to return to the Moon for long-term human exploration and accelerating efforts to send American astronauts to Mars.' NASA declined to comment beyond Petro's statement. NASA contracts remain one of the most significant and steady sources of funding for the space industry, which has allowed the agency to set the direction for many businesses. But that balance of power is shifting, and cuts to NASA's funding could cause its leadership to fade. 'NASA would, in a sense, define access and define the culture of spaceflight and define the ambitions of spaceflight,' Dreier said. 'Now, they have competitors for that, and frankly, some of their competitors are laying out more ambitious programs.' Challenging Missions While NASA has evolved into a technical adviser and financial backer for space companies, pure science has remained part of its mission. NASA's transition to more commercial partnerships was started, in part, to free up money to spend on exotic, challenging missions with no obvious near-term commercial rewards. Pulling back is likely to have consequences. Trump's broader push to curtail funding for science — the administration has choked off money for medical, climate and other research — risks eroding an important source of American soft power. After the end of the Cold War-era space race, NASA became a vessel for international cooperation, proving countries with lofty goals can work together. Many of the NASA missions Trump has proposed canceling or pulling away from entailed collaboration with European allies. The prospect of reduced funding is also causing worry about agency talent. Already, NASA is competing with the private space industry for engineers. Shutting down missions could push agency scientists to seek other opportunities. 'Folks are very worried about what they're going to do now with their lives, and where they're going to go,' said Hendrix, the Planetary Science Institute's CEO. The long-term outlook for NASA is difficult to discern. In the coming years, it is expected to continue its Artemis moon program, and start a new program for human exploration of Mars, with commercial companies at the forefront. But the scientific ambitions that long helped define NASA appear likely to become more limited. 'If we elect to say we no longer want to understand our origins, or we no longer want to challenge ourselves to see if there's life out in the cosmos, that is the equivalent of turning our heads down and burying ourselves in our cell phones when we're standing at the edge of the Grand Canyon,' said The Planetary Society's Dreier. 'We miss something more profound and big and deep that we otherwise have no access to in our modern society.'

James Webb Space Telescope reveals first exoplanet with 'sand rain' and a growing 'sandcastle' companion, redefining planetary evolution
Source: NASA James Webb Space Telescope (JWST) has discovered something incredible. A far-off planetary system with gas giants that are packed with coarse silica, which is a space sand. The YSES-1 system , which surrounds a young star 300 light-years from Earth, consists of two planets, YSES-1 b and YSES-1 c, both of which have atmospheric sand clouds. The system is a mere 16.7 million years old, an infant in cosmic age that presents scientists with the unusual chance to watch planet formation and development unfold in real-time. These results may redefine the knowledge of the formation and evolution of planets, including those within our own solar system, over billions of years. NASA's James Webb Space Telescope detects 'sand clouds' made of silicates According to the study, silicate clouds, or sand clouds, consist of mineral grains such as pyroxene and forsterite, iron-containing compounds found in rocky planets and meteorites. They are more than a novelty in the atmospheres of exoplanets; they contain important clues about the chemistry and atmosphere of far-off worlds. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Buy Brass Idols - Handmade Brass Statues for Home & Gifting Luxeartisanship Buy Now Undo According to Italy's National Institute for Astrophysics (INAF) scientist Valentina D'Orazi, the silicates seen in these planets go through sublimation and condensation cycles just like water on Earth. These active cycles help the sand clouds stay suspended in the air, indicating sophisticated atmospheric transport and formation processes. JWST reveals silicates in both exoplanet atmospheres and formation disks Of the two gas giants, YSES-1 b is a still-growing planet that could someday be a large Jupiter analogue. It is encircled by a flattened cloud of material, a circumplanetary disk; a phenomenon common around young planet. The disk holds the planet-building blocks of its atmosphere, silicates, which fuel its growth. YSES-1 c, however, is already enormous, around 14 times as massive as Jupiter. Its atmosphere has a reddish color due to suspended silica, which sometimes rains down as sandy rain to the planet's center. This is the first direct detection of silicates not only in an exoplanet atmosphere but also in a circumplanetary disk. That makes this observation historic and also pivotal to the study of planetary science. How JWST made the discovery possible The James Webb Space Telescope was able to image these subtle details due to the extended orbits of the planets around their parent star. These were distances ranging from five to ten times the distance between the Sun and Neptune, and they enabled astronomers to view the planets without the blinding light of the star. With its sophisticated infrared equipment, JWST gathered high-resolution spectral information that, on analysis, showed the presence of silicate particles and their composition. Although such direct observation remains possible only for a few exoplanets at this time, it highlights JWST's unparalleled capability to observe in detail the atmospheres and environments of other worlds. JWST insights reveal how Jupiter and Saturn may have taken shape One of the most intriguing things about this discovery is what it implies about the early history of our own solar system. By looking at young exoplanets such as YSES-1 b and c, astronomers can deduce how gas giants such as Jupiter and Saturn might have formed and developed. "Examining these planets is like peeking into the history of our own planetary back yard," D'Orazi explained. "It confirms that young exoplanet atmospheres and the disks around them are key drivers of their final atmosphere composition." The researchers also highlighted the need for detailed atmospheric models to interpret the JWST's excellent data pointing to the telescope's continued role in pushing the frontiers of planetary science and exoplanet study. These historic findings were released on June 10 in the journal Nature and highlighted the same day during the 246th American Astronomical Society meeting in Anchorage, Alaska.
