Astronomers have determined that the atmosphere of super-Earth Gliese 1214 b is likely water-rich. However, this exoplanet is no Earth twin.

Likewise, Gliese 1214 b has proven difficult to observe due to its highly reflective atmosphere — until JWST turned its powerful gaze towards the alien world.

This suggests that instead of a Neptune-like exoplanet, that GJ 1214 b is more of a super-Venus exoplanet, which is astounding since its orbital period is only 1.6 days, whereas the orbital period of ...

When combined with the findings of previous observations in other colors, this new observational result implies that GJ 1214 b is likely to have a water-rich atmosphere.

A Japanese research team has used the Subaru Telescope to determine that the super-Earth-sized planet Gliese 1214 b (GJ 1214 b) is likely to have a water-rich atmosphere.

The planet is known as Gliese 1214b or just GJ 1214b for short. It orbits a star called Gliese 1214, about 48 light-years from Earth.

Gliese 1214b is about 2.7 times Earth’s diameter and is almost 7 times as massive. It is located 42 light years away in the constellation Ophiuchus.

Six times as massive as Earth, Gliese 1214 b is less than three times as wide, falling between the Earth and the solar system's ice giants Uranus and Neptune in size.
