If there’s extraterrestrial life anywhere in the galaxy, chances are, it could be on LHS 1140b.
Astronomers have found that the exoplanet 48 light years away is spewing helium into space, a strong sign that it harbors a robust atmosphere, they reported in a new study published in the journal Science.
And that’s not all: it’s also a rocky world like our own, and orbits within its star’s habitable zone, the region around a star where a planet can maintain liquid — and possibly life-harboring — water on its surface.
If their findings are borne out, then it’s the first ever Earth-like exoplanet we’ve seen with an atmosphere stable enough to support life — and could vindicate the belief that there’s a whole host of similar planets out there, rather than our own being a rare anomaly in the cosmos.
