dark matter
A few years ago, a group of scientists discovered Trappist-1, a red star 39 light years away around which several life-on-another-planet/” title=”Why scientists say we are close to finding life on another planet”>planets revolved that could host oceans and life. But now, a new study has concluded that no living organism can exist in them.
On October 16, 2016, a team of astronomers from Belgium announced to the world the discovery of three Earth-like planets around Trappist-1, a small red star 39 light-years away. Just a few months later, in February 2017, four more planets were discovered there, all of them rocky and temperate. It was something unheard of. Seven worlds similar to ours around the same star. And three of them, furthermore, right in the habitable zone, that is, at the precise distance so that their surface temperature allows the existence of water in a liquid state. Hopes of finding great oceans there, and perhaps life, spread like wildfire throughout the world.
But the dream now seems to be over. A new study, in fact, has been a real blow of cold water on the possibilities of finding life in this promising solar system, and has concluded that the seven planets, stripped of their atmospheres by the star, are currently dry, arid and in which no living organism can exist. The discouraging work has just been published in ‘Astronomy & Astrophysics’.
