Fast Summary
- K2-18b Discovery: K2-18b,a planet 124 light-years away in the Leo constellation,shows signs of potential atmospheric biosignatures as per a Cambridge-led study using the James Webb Space Telescope (JWST).
- Key Findings: JWST detected sulfur-based molecules, dimethyl sulfide (DMS) and dimethyl disulfide (DMDS), which on Earth are produced only by microscopic life such as phytoplankton. Though, thes findings are not statistically definitive.
- Scientific Debate: Experts remain skeptical. Astrobiologists cite issues wiht statistical meaning and inconsistencies in associated chemical data from the atmosphere.
- Clarifications by Researchers: Lead author Nikku Madhusudhan emphasized no strong claim of detecting life was made but shared excitement about “potential for life.”
- Data Reanalysis Outcomes: Autonomous studies using JWST data have failed to replicate DMS detection or show statistically significant evidence for its presence.
- Next Steps: Scientists aim to conduct additional observations with JWST and compare DMS findings across similar planets while searching for alternate explanations for these signals.
