Scientists have detected compounds in exoplanet K2-18b’s atmosphere that are exclusively produced by living organisms on Earth, hinting at potential extraterrestrial life. This groundbreaking discovery, made by the James Webb Space Telescope, represents the strongest evidence yet for biological activity beyond our solar system.

Key Takeaways:

• The telescope detected Dimethyl Sulfide and Dimethyl Disulfide in K2-18b’s atmosphere, compounds primarily produced by biological processes on Earth
• K2-18b is a “Hycean” world 124 light-years away with potential oceans and temperatures suitable for liquid water
• Current findings have a “three-sigma” confidence level, requiring additional observation to reach the five-sigma scientific standard
• The estimated DMS concentration exceeds Earth’s levels by 10 parts per million, compared to less than 1 part per billion on our planet
• If confirmed, this discovery could fundamentally transform our understanding of life in the universe
