Scientists have found a vast planet, so large that it should not exist. The planet appears to be too big for its sun, and therefore calls into question our understanding of how planets and solar systems form, according to the researchers who found it. The planet is more than 13 times as massive as Earth. It orbits around a star that is nine times less massive than our Sun. As such, the ratio between the two of them is 100 times higher than it is between the Earth and our sun. It is the first time that a planet with such a high mass has been seen orbiting a star with such a low amount of mass. And the discrepancy is so large that scientists thought such a planet could not exist. “This discovery really drives home the point of just how little we know about the universe,” said Suvrath Mahadevan, from Penn State. “We wouldn’t expect a planet this heavy around such a low-mass star to exist.” When stars are formed, out of large clouds of gas and dust, that material sticks with the star as a disc that orbits around it. Planets can then form out of that extra material, and go on to make a planetary system like our own. But science would suggest that the disc around the star in the new paper, known as LHS 3154, would not have enough material to make a planet so large. “The planet-forming disc around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. “But it’s out there, so now we need to reexamine our understanding of how planets and stars form.” The finding is reported in a new paper, ‘A Neptune-mass exoplanet in close orbit around a very low mass star challenges formation models’, published in Science.

Scientists have found the first ever disc structure around a star outside of our own Milky Way. The disc is around a young massive star forming in a stellar nursery called N180. It is within the Larg Magellanic Cloud, a dwarf galaxy that neighbours ours. The disc is 163,000 light years from Earth – meaning that it is not only the first to be detected outside of our galaxy, but also the most distant such disc ever seen. Matter cannot fall straight into a star. Instead, it flattens out, making a disc that spins around the star. Closer to the star, the disc rotates faster. Scientists caught that difference in speed using telescopes, confirming that it is a disc around a distant star. Scientists have seen such discs before, but only in our own galaxy. Being able to see them outside of the Milky Way is a remarkable feat of technology, scientists said. Lead author of the study, Dr Anna McLeod from Centre for Extragalactic Astronomy, Durham University said: “When I first saw evidence for a rotating structure in the ALMA data, I could not believe that we had detected the first extragalactic accretion disc; it was a special moment. “We know discs are vital to forming stars and planets in our galaxy, and here, for the first time, we’re seeing direct evidence for this in another galaxy. “We are in an era of rapid technological advancement when it comes to astronomical facilities. “Being able to study how stars form at such incredible distances and in a different galaxy is very exciting.” The findings are reported in a new article, ‘A likely Keplerian disk feeding an optically revealed massive young star’, published in Nature.
