James Webb Found a Planet With 99.8% Chance of Life

In April 2025, a team of scientists announced that the James Webb Space Telescope had detected a molecule in the atmosphere of K2-18b that on Earth is produced exclusively by living organisms. The announcement made headlines around the world. Scientists reported a 99.7 percent statistical confidence in the signal. For a few weeks, the question everyone was asking was the same: had we finally found evidence of life beyond our solar system? What happened next is the real story. At least five independent research teams reanalyzed the same data and reached very different conclusions. This video explains what the original announcement actually claimed, what the follow-up science found, and where the research stands today. K2-18b is a real planet, 120 light-years away, with a genuine ocean world hypothesis supported by confirmed detections of methane and carbon dioxide. The question of what else might be there remains open. Subscribe for weekly space documentaries. #JamesWebb #K2-18b #SpaceDocumentary #Exoplanets #Astrobiology #SpaceScience #NASA
