1:34:41A Biosignature Was Found On An Exoplanet | The Signal Was Gone Before Anyone Could Confirm It
A telescope a million miles from Earth read the air of a planet 120 light years away and found a molecule that, on our world, only living things make. The molecule was dimethyl sulfide, the planet was K2-18 b, and the instrument was the James Webb Space Telescope. Then Webb looked again and the signal had weakened. Some features were fainter, others were gone. This Acronium film is built on one disciplined distinction that the narrator never lets you forget: this was a tentative detection, not a confirmation.
