Astronomers planned a Webb observing program to test whether habitable-zone planet LHS 1140 b retains a substantial atmosphere or presents a bare surface. Space Telescope Science Institute materials ...

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 ...

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 ...

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone. The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space.

A international team of astronomers has made an exciting discovery about the temperate exoplanet LHS 1140 b: it could be a promising 'super-Earth' covered in ice or water. A international team of ...

A new study from researchers at the University of Montreal suggests that exoplanet LHS 1140 b is most likely a super-Earth. That would make it more massive than Earth, yet lighter than our solar ...

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 ...

Here's your friendly reminder that we're probably not alone in this universe, although at this point aliens must think humans are the most annoying neighbors in the solar system. This week, Harvard ...

(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.
