James Webb Telescope Identifies Potential Ocean World LHS 1140b

The exoplanet, located 48 light-years away, may have a nitrogen-rich atmosphere and significant water coverage.

LHS 1140b is situated in the habitable zone of a red dwarf star in the constellation Cetus.
The planet is about 1.7 times larger and 5.6 times more massive than Earth.
Researchers found no hydrogen, suggesting a secondary atmosphere rich in nitrogen.
Possible scenarios include an ice-covered world or a 'bull’s eye ocean' with liquid water.
Further observations are needed to confirm the presence of carbon dioxide and better understand the planet's conditions.
