A revised analysis of a nearby exoplanet, published June 30 in The Astrophysical Journal, has dramatically improved its habitability credentials. The study reveals that GJ 3378b — a super-Earth ...

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space.

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...
