About

How do stars influence the search for life? When astronomers search for life on other worlds, they look for atmospheric molecules called biosignatures, or gases that could indicate biological activity. But starlight can dramatically alter a planet’s atmosphere through photochemistry, sometimes creating or destroying these signals. A NASA scientist explains why understanding a planet’s star is essential when searching for life beyond our solar system.
