In a potential landmark discovery, scientists using the James Webb Space Telescope have obtained what they call the strongest signs yet of possible life beyond our solar system, detecting in an alien planet's atmosphere the chemical fingerprints of gases that on Earth are produced only by biological processes.

Scientists using The James Webb Space Telescope have uncovered potentially earth-shattering evidence indicating that a faraway world could be home to alien life.

NASA’s James Webb Space Telescope detected an intriguing compound in the atmosphere of the exoplanet K2-18 b, but scientists are divided about what the chemical means
