JWST K2-18b Biosignature Claim Faces Scrutiny: Another False Alarm?

The James Webb Space Telescope's (JWST) detection of potential biosignature gases in the atmosphere of exoplanet K2-18b has sparked excitement about extraterrestrial life. However, a reanalysis by a University of Oxford scientist suggests the data is too noisy to draw firm conclusions. While the original research team defends their methodology, some experts argue the evidence is insufficient to support claims of extraterrestrial life, fearing that such premature announcements might erode public trust in science. Further analysis by other scientists is expected, and the final conclusion remains pending.
