Scientists find strongest evidence yet of life on an alien planet

In a groundbreaking discovery, astronomers believe they may have found the most compelling evidence of life beyond Earth. A planet located 124 light-years away, known as K2-18b, has revealed two chemical signatures in its atmosphere that are only produced by life on Earth, reported Mirror.

Researchers say they are now 99.7% sure that some form of life exists on the planet, which lies more than three billion times farther from us than the distance between Earth and the Moon. The gases detected, dimethyl sulphide (DMS) and dimethyl disulphide (DMDS), are typically made by microscopic marine algae on our planet.
