James Webb telescope sees potential indicators of alien life within the environment of a distant ‘Goldilocks’ water world

Earlier this week, Stay Science reported that NASA’s James Webb House Telescope (JWST) might possible detect indicators of extraterrestrial life on an Earth-like planet as much as 50 light-years away. Now, a brand new examine reveals that the state-of-the-art spacecraft could have already noticed one such trace of life — “alien farts” — within the environment of a doubtlessly ocean-covered “Goldilocks” world greater than twice as distant.     

The exoplanet in query, K2-18 b, is a sub-Neptune planet (between the dimensions of Earth and Neptune) that orbits within the liveable zone round a purple dwarf star roughly 120 light-years from the solar. K2-18 b, which is round 8.6 occasions extra huge than our planet and round 2.6 occasions as broad, was first found by NASA’s Kepler telescope in 2015. And in 2018, NASA’s Hubble telescope found water within the exoplanet’s environment.
