Did James Webb Find Signs of Life? What the Data Actually Says

Have we just uncovered life beyond Earth? Some 120 light-years away in the constellation Leo, the James Webb Space Telescope (JWST) has spotted something remarkable K2-18 b, a world where life-driven chemistry may already be unfolding. Its atmosphere seems to teem with dimethyl sulfide, a molecule on Earth made only by living organisms. Many scientists now put the odds at about 99% that this could be the first truly habitable planet beyond our Solar System. This film guides you through the breakthrough—from Webb’s earliest, whisper-faint signals to the dawning idea that the universe may be alive. - Subscribe to Milky Stellar for more deep dives into: • Space & Astronomy • Cosmic Mysteries • Universe Theories & Discoveries • Science that feels like storytelling ✦ We bring the universe closer to you. ✦ - TimesCode: 00:00 Tonight's Map 04:41 Reading the Air 15:43 Confirmed vs Contested 30:32 The “Hycean” Picture 42:29 False Positives 54:45 The Star, Photochemistry, and the Shape of the Spectrum 01:07:35 Standards of Evidence: How We Decide What to Believe 01:19:02 The Next Telescopes and the Tests That Will Decide 01:32:03 Implications & Protection 01:44:34 Campaign Roadmap 01:56:38 What’s Next Keywords: James Webb Space Telescope, JWST, K2-18 b, alien life, exoplanet, NASA discovery, habitable planet, dimethyl sulfide, red dwarf, signs of life, astrobiology, space documentary, space exploration, universe, astronomy, life beyond Earth,water planet,water beyond earth,water vapor,rocky planet,red dwarf star
