The Cambridge scientist who thinks he’s just discovered alien life

Is there life on...K2-18b?

Professor Nikku Madhusudhan believes he has discovered alien life on an exoplanet 120 light years away from Earth.

Speaking to Tom Swarbrick, he puts the chances of there being life on the faraway planet at '50/50'.

At the time of upload, the James Webb Space Telescope was observing the planet, and the analysis will take a few months. It follows the discovery of carbon dioxide on the planet in scans last year.
