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 ...

The James Webb Space Telescope has discovered exoplanet GJ 1214 b, situated 48 light-years away in the constellation Ophiuchus. This planet has a dense carbon dioxide atmosphere, presenting a ...

GJ 1214b is a very different place, and it has an intriguing history. At one point, that water might well have been ice, and as the planet’s orbit wended its way closer to its star, it may have ...

Magma ocean planets that contain water – like the earthlike exoplanet GJ 1214 b in this artist’s concept – will only host a tiny fraction of this water on their surface. The majority of it ...

Webb tracked the full orbit of GJ 1214 b, allowing scientists to create a “heat map." This map showed a big change in temperature between the mini-Neptune’s day and night sides — only ...

Magma ocean planets that contain water – like the earthlike exoplanet GJ 1214 b in this artist’s concept – will only host a tiny fraction of this water on their surface.

Astronomers using NASA’s state-of-the-art James Webb Space Telescope have made a groundbreaking discovery of GJ 1214 b, a planet unlike any we've seen before. Located 48 light-years away in the ...

GJ 1214 b is tidally locked, meaning it has a permanently star-facing "day side" and a perpetual "night side" that always stares out into space.

GJ 1214 b is part of a family of planets that are also called mini-Neptunes. That's because they have a rocky composition, possibly oceans above that, and an atmosphere rich in hydrogen.

NASA’s James Webb Telescope uncovers GJ 1214 b, a super-Venus exoplanet with a carbon dioxide-heavy atmosphere, challenging planetary classification and offering new insights into planetary ...
