"Exoplanet Discovery: Boiling Ocean Raises Questions About Habitability"
Astronomers have discovered a potentially water-covered planet, TOI-270 d, about 70 light years away, with a temperature hot enough to boil water. Data from NASA's James Webb Space Telescope suggests it could be a "Hycean world" with a large ocean and hydrogen-rich atmosphere, but other scientists believe it may have a rocky surface and dense, super hot steam atmosphere. The discovery showcases our ability to detect chemical signatures of distant exoplanets, raising the question of whether we will ever find a planet as hospitable as Earth.
