Gliese 12 b, a temperate Earth-sized planet, has a surface temperature that is cool enough for life
Humanity could be closer to finding a second home, thanks to the discovery of a new Earth-sized planet that could support human life. If this planet has an atmosphere, astronomers think it could also hold water – and maybe, just maybe, even host alien life on its surface.
Published in the Monthly Notices of the Royal Astronomical Society, the new study describes the rocky exoplanet known as Gliese 12 b. It has the same surface temperature as the UK in the 2022 heatwave – a balmy 42ºC (107ºF) – making it, in theory, habitable.
