Doubts grow about the biosignature approach to alien-hunting
Phosphine detection on Venus remains controversial and raises questions about biosignature evidence for alien life. Exoplanet atmosphere studies face similar challenges.
Have We Already Found Alien Life?
The James Webb Space Telescope may have detected life beyond Earth, with strong evidence for a biosignature forthcoming.
While the detection of a biosignature is intriguing, it falls short of confirming life on other planets due to uncertainties and the complexity of defining life.
