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

Astronomers have detected helium leaking from a rocky exoplanet, a sign that the planet may have an atmosphere. If confirmed, the finding represents the first such detection around an Earth-like world ...

More than 6,000 exoplanets have now been confirmed beyond our Solar System, but only ...

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 ...

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 ...

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 ...

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 ...
