US EditionScientists Detect Strongest Evidence Yet of Potential Life on Exoplanet K2-18 b
- A Cambridge team reported hints of dimethyl sulfide on exoplanet K2-18b using the JWST.
- Previous work suggested DMS could be a biosignature, prompting the team to analyze K2-18b's atmosphere.
- The team used JWST to observe light passing through K2-18b's atmosphere, searching for molecular signatures.
- The team found a signal with a three-sigma statistical significance, suggesting only a 0.3% chance of error.
- Despite the exciting find, the authors and other experts urge caution, pending further validation and data.

Are We Finally Not Alone? Webb Detects Life’s Signature on Distant Ocean Planet
Astronomers may have found the strongest hint of life beyond Earth thanks to new data from the James Webb Space Telescope. They’ve detected sulfur-based molecules in the atmosphere of exoplanet K2-18b that, on Earth, are only produced by living organisms. While the evidence isn’t conclusive yet, it matches predictions for a “Hycean” world
A team of astronomers led by the University of Cambridge has detected chemical traces of possible signs of life on a planet outside the solar system. Using data from the James Webb Space Telescope (JWST), they identified the dimethyl sulfide molecules (DMS) and/or dimethyl disulfide (DMDS) in the atmosphere of the exoplanet K2-18b, which orbits within the habitable zone of its star. On Earth, these molecules are only produced by living organisms…
Scientists Detect Signs of Alien Life on Exoplanet K2-18b
Scientists have uncovered compelling evidence of alien life on exoplanet K2-18b, located 124 light-years away, using NASA’s James Webb Space Telescope. The team detected traces of dimethyl sulfide (DMS) and dimethyl disulfide (DMDS) in the [...] The post Scientists Detect Signs of Alien Life on Exoplanet K2-18b appeared first on The People's Voice.
Scientists find signature of life on a distant planet, study suggests
A team of astronomers has detected what they call the most promising signs to date of a possible biosignature, or signs of past or present life linked to biological activity, on an exoplanet named K2-18b.
Life is the only thing that still makes Earth a special place in the universe, says researcher Mikko Tuomi. That's why searching for it is so interesting.
