A rocky exoplanet 48 light-years from Earth has offered the 'strongest evidence yet' that other planets besides Earth could be hospitable to life.

An ancient rocky world so close to its star that its surface is largely molten should have been stripped bare of gas long ago. Instead, new observations reveal that this ultra-hot planet has somehow ...

A rocky super-Earth 48 light-years away, approximately 1.7 times the diameter and 5.6 times the mass of our planet, may be capable of sustaining life. The exoplanet, LHS 1140 b, was leaking helium, ...

Mars holds a special place in the solar system. It represents marginal habitability. This means it transitioned from warm and wet and potentially hospitable, to cold and dry and inhospitable. "Mars is ...

What do the surfaces of rocky exoplanets look like? This is what a recent study published in Nature Astronomy hopes to address as a team of scientists investigated how heat measurements could be used ...

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a ...

In this artist’s concept, the exoplanet LHS 1140b is shown in the foreground, surrounded by a helium-rich atmosphere. Another nearby rocky planet orbits the same cool red dwarf star in the ...
