Did the James Webb telescope really find evidence of alien life? Here’s the truth about exoplanet K2-18b.

The trendiest planet in the universe right now is K2-18b, a potentially habitable world swirling around a small, red star in the constellation Leo. Located 124 light-years from Earth, the mysterious planet will never host human visitors — but a recent glimpse with the James Webb Space Telescope (JWST) hints that alien life may already thrive there in a vast, warm ocean.

In a University of Cambridge-led study published April 17, scientists using JWST reported the detection of possible signs of life in the alien planet’s atmosphere, offering what a Cambridge statement called the “most promising” evidence yet of life beyond Earth. However, in the week since the study’s publication, a growing number of scientists are already pushing back on this big claim.
