"NASA's Webb Telescope Uncovers Potential Water World with Signs of Life"
The Webb Space Telescope has detected possible molecular signals on the exoplanet K2-18 b, suggesting it may be a Hycean world covered in a global ocean with a hydrogen atmosphere. The telescope observed signs of water vapor on the exoplanet, which lies in its star's habitable zone. The presence of carbon-bearing molecules indicates the possibility of a water ocean beneath the hydrogen atmosphere. Additionally, the telescope detected a potential detection of dimethyl sulfide, a molecule produced on Earth by living organisms. Further observations will be conducted to confirm the presence of dimethyl sulfide and better understand the nature of this water world.
