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.

A giant planet located 124 light years from Earth may be showing the strongest signs yet of possible life beyond our solar system, according to new findings by astronomers using the James Webb Space Telescope.

Astronomers have found what they describe as the strongest evidence yet of possible life beyond the solar system, following the detection of key chemical signatures in the atmosphere of a distant exoplanet.
