Exoplanet discovery marks major breakthrough in search for life, scientists say

Planets bigger than Earth but smaller than Neptune could be habitable, study suggests

And it suggests that they could be habitable in just the way scientists had hoped. Watch more Nasa loses contact with satellite monitoring mysterious exoplanets Dr Nikku Madhusudhan from Cambridge's Institute of Astronomy, who led the study, said:"Water vapour has been detected in the atmospheres of a number of exoplanets but, even if the planet is in the habitable zone, that doesn't necessarily mean there are habitable conditions on the surface. "To establish the prospects for habitability, it is important to obtain a unified understanding of the interior and atmospheric conditions on the planet - in particular, whether liquid water can exist beneath the atmosphere." Because of the size of K2-18b, some suggest it would be more like a smaller version of Neptune than a larger version of Earth. It is thought a mini-Neptune would have a significant hydrogen envelope surrounding a layer of high-pressure water, with an inner core of rock and iron. If this envelope is too thick, it would be too hot, and pressure at the surface of the water layer beneath would be far too great to support life. According to the new study published in The Astrophysical Journal Letters, despite the size of K2-18b, its hydrogen envelope is not necessarily too thick and the water layer could support life. Astronomers used the existing observations of the atmosphere, to confirm the atmosphere is hydrogen-rich with a significant amount of water vapour. They also found that levels of other chemicals such as methane and ammonia were lower than expected. But whether these levels can be attributed to biological processes remains to be seen. The researchers found that the maximum extent of the hydrogen envelope allowed by the data is around 6% of the planet's mass, though most of the solutions require much less. The minimum amount of hydrogen is about one-millionth by mass, similar to the mass fraction of the Earth's atmosphere. Additional reporting by agencies Read more: The Independent

Who exactly are you trying to fool with this narrative ?! You either find life or you don't. You cannot be dead if you are alive. Could, perhaps, maybe, might... make an announcement when you actually FIND life on another planet. You can go no where, the way is shut! Only 124 light years away - see you there!

Adults to be automatically enrolled as organ donors under new law‘Too many people lose their lives waiting for an organ,’ says Matt Hancock I'm going to feel like an asshole when I unroll myself now thanks We need to be careful when we are worth more dead. This is a positive step as there's a huge organ shortage in the UK. UK Patients are dying waiting for organ transplants. Organs are needlessly discarded as we cannot assess organs before transplant.
