A study has suggested it might be possible to detect aurorae on Proxima b, the closest exoplanet to Earth, which might tell us about the planet’s potential habitability. The rest of this article is ...

Scientists have confirmed the existence of the exoplanet Proxima b, a planet just 4.2 light-years from Earth. Given how close it is to its star, Proxima Centauri, it could have liquid water, and ...

A group of dozens of astronomers have found evidence of a small, rocky, and potentially watery world lurking around the closest star to the sun. The planet, called Proxima b, is slightly larger than ...
