Finally! NASA's Webb Telescope Finds Possible Life Signals in Water Rich Exoplanet

Breakthrough: Webb Telescope Finds Possible Life Signals in Water-Rich Hycean Exoplanets "What if we’ve been looking for alien life in the wrong places? Earth-like planets may not be the only—or even the best—homes for life in the universe. Thanks to the James Webb Space Telescope, scientists have discovered a whole new class of planets where life could thrive… and they might be everywhere. "Meet Hycean worlds—exotic planets with deep, global oceans and thick hydrogen atmospheres. These mysterious worlds could be the ultimate cosmic oasis for alien life… and Webb might have already found one." "Take K2-18b, a planet 124 light-years away. Hubble detected water vapor in its atmosphere, but Webb went further—finding carbon dioxide, methane, and even hints of dimethyl sulfide, a gas made by Earth’s plankton. Now, scientists say another clue—methyl halides—could be the definitive sign of life on Hycean worlds." "Unlike Earth-like planets, Hycean worlds give us a much clearer signal. Their thick atmospheres amplify bio signatures, making them easier to detect." "Methyl halides could be detected in just 13 hours of Webb observations. That’s a game-changer—it’s faster and cheaper than hunting for oxygen." "If life exists here, it wouldn’t look like us. These would be anaerobic microbes, breathing hydrogen instead of oxygen—surviving in conditions we can barely imagine."
