Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.

"It's in the habitable zone, which is super exciting for astrobiology and habitability and searching for life."

For the first time, scientists found that a rocky planet in the habitable zone of its star has an atmosphere. It’s the best place to look for alien biosignatures, scientists say.
