Alien super-Earths may get habitability boost from atmospheres

Alien rocky worlds cocooned in hydrogen and helium could prove habitable to life as we know it for billions of years, with key features such as temperate conditions and liquid water, a new study finds.

On Earth, there is life virtually wherever there is water. As such, the search for extraterrestrial life has often focused on worlds whose surfaces are temperate enough to host liquid water, which astronomers dub as habitable. Aside from this prerequisite, scientists remain uncertain to what extent exoplanets have to resemble Earth in order to support life.
