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.

Researchers at Cambridge University's Institute of Astronomy have found evidence that could support proof of life on K2-18b, a large and distant planet that's approximately 700 trillion miles away from Earth.
