If there was oxygen on a far away planet, how would we know? Scientists use computer models to simulate what oxygen would look like on far away planets and found a chemical signature that helps us tell the difference between oxygen from life and oxygen from other sources.

Detecting Distant Planet Atmospheres From Afar Recent research on exoplanet GJ 1132 b that revolves around a M-dwarf star has discovered an atmosphere with traces of compounds existing on Earth

By Nandita Hari Guest Contributor Humans have always been fascinated with the vastness of the universe and its hidden truths. For ages we have tried to explore and study the sky. The earliest study of the sky involved using the READ MORE
