‘Are We Alone?’ Study Refines Which Exoplanets Are Potentially Habitable ESO/L. Calçada

In order to search for life in outer space, astronomers first need to know where to look. A new Northwestern University study will help astronomers narrow down the search. The research team is the first to combine 3D climate modeling with atmospheric chemistry to explore the habitability of planets around M dwarf stars, which comprise about 70% of the total galactic population. Using this tool, the researchers have redefined the conditions that make a planet habitable by taking the star's radiation and the planet's rotation rate into account.
