"NASA's Webb Telescope Uncovers Potential 'Hycean' Planet with Water Ocean and Signs of Life"

NASA's James Webb Space Telescope has provided evidence suggesting the presence of an ocean on a massive exoplanet called K2-18 b, located over 100 light-years away in the constellation Leo. The planet, 8.6 times the mass of Earth, exhibits an atmosphere containing methane and carbon dioxide, consistent with an ocean-covered surface beneath a hydrogen-rich atmosphere. While the detection of dimethyl sulfide raises the possibility of biological activity, further observations are needed to confirm this finding. The planet's large size and potential high-pressure ice mantle may make it inhospitable for life, but the discovery highlights the importance of exploring diverse habitable environments in the search for extraterrestrial life.
