Using data from the James Webb Space Telescope, researchers have determined that an exoplanet dubbed LHS 1140 b may be an icy water world that could potentially harbor an Earth-like atmosphere and even support life.
However, recent data from the JWST suggests LHS 1140 b is instead a rocky or icy, water-rich "super Earth," making it an even better candidate to look for extraterrestrial life than initially thought. "LHS 1140 b is one of the best small exoplanets in the habitable zone capable of supporting a thick atmosphere, and we might just have found evidence of air on this world," he added.and has over six times the mass of Earth, has already intrigued scientists given its proximity to the solar system. The latest findings are only adding to the excitement.
It's still too early to conclude if LHS 1140 b is a super Earth that's cloaked in nitrogen, much like our own atmosphere. But observations suggest anywhere between ten to 20 percent of its mass may be composed of water, which means it could either be a massive snowball or lump of ice with a sub-surface ocean.
