Scientists say that water worlds – planets with deep, global oceans – might be fairly common in our Milky Way galaxy. These worlds would have even more water than Earth. Could anything live there? And ...

Researchers have identified a temperate exoplanet as a promising super-Earth ice or water world. The planet, LHS 1140 b, is located about 48 light-years away in the constellation Cetus. It emerges as ...

(Nanowerk News) When the exoplanet LHS 1140 b was first discovered, astronomers speculated that it might be a mini-Neptune: an essentially gaseous planet, but very small in size compared to Neptune.

The search for Earth’s twin just got a little closer as astronomers recently presented findings regarding a potential icy or watery “super-Earth” called LHS 1140 b, which is located approximately 49 ...

Temperate exoplanet LHS 1140 b may be a world completely covered in ice (left) similar to Jupiter’s moon Europa or may be an ice world with a liquid substellar ocean and a cloudy atmosphere (centre).
