Astronomers caught helium escaping the habitable-zone world LHS 1140 b — a signal that strengthens the case for the planet's ...

There are no confirmed exomoons, moons orbiting distant exoplanets in other solar systems. There are a few candidates, but none have passed the threshold and been accepted as confirmed. But they must ...

Science has discovered around 6,000 planets, and this is the first one, other than Earth, that is rocky and has an atmosphere.

A rocky planet about 49 light-years from Earth appears to have held onto an atmosphere, despite orbiting a red dwarf capable of stripping gases into space. The evidence comes from helium escaping ...

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.

How does a star affect the makeup of its planets? And what does this mean for the habitability of distant worlds? Carnegie's Luke Bouma is exploring a new way to probe this critical question—using ...

How can scientists determine if exoplanets orbiting M-dwarf stars are habitable? This is what a study recently presented at the 247th Meeting of the American Astronomical Society hopes to address as a ...

In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in ...

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 ...
