Geology helps astronomers find habitable planets

Astronomers have identified more than 4,000, and counting, confirmed exoplanets — planets orbiting stars other than the sun — but only a fraction have the potential to sustain life. Now, new research is using the geology of early planet formation to help identify those that may be capable of supporting life. https://www.sciencedaily.com/releases/2021/05/210504112533.htm
