- James Webb discovers a rare giant planet with surprisingly Earth-like temperatures
NASA's James Webb Space Telescope has discovered TOI-199b, a rare Saturn-sized gas giant located 330 light-years away with surprisingly Earth-like temperatures and a methane-rich atmosphere. This discovery represents one of the first detailed studies of a 'temperate' gas giant, a type of exoplanet previously unknown in our solar system.
