Exoplanetary Systems are Diverse. Our Search for Life Should Be the Same

Universe Today - Fri, 06/20/2025 - 8:57pm

With over 5,000 exoplanets now identified, astronomers have found that our Solar System isn't the only model of planetary formation. There are super-Earths, sub-Neptunes, hot-Jupiters, and Earth-sized worlds orbiting around red dwarf stars. In a new paper, researchers propose how the search for life could adapt to these bizarre environments, expanding the definition of a habitable world. Life could exist without a surface, or using different kinds of solvents than water.
