A team from the University of Cambridge suggests they have found evidence of biological activity on the exoplanet K2-18 b, potentially indicated by the molecule dimethyl sulfide in its atmosphere. Despite these claims, astronomers express skepticism, urging that the evidence is not strong enough to confirm life. Using the James Webb Space Telescope, researchers analyzed starlight through the planet's atmosphere, revealing chemical signatures that could be linked to biological processes. However, many in the scientific community emphasize that findings are not definitive, highlighting the need for further exploration of these biosignatures.
Using the James Webb Space Telescope, astronomers detected hints of dimethyl sulfide in the atmosphere of K2-18 b, suggesting potential biological activity.
Despite this exciting claim, many scientists urge caution, indicating the evidence for biological activity remains weak and not conclusively linked to life.
