Using Exoplanets as Dark Matter Detectors

This exoplanet, a gas giant called GJ 504b, is about 57 light-years away from Earth. Exoplanets like this may help researchers find and measure dark matter.

Dark matter makes up roughly 80% of the universe’s mass, yet it can’t be directly observed. New research led by Juri Smirnov, a fellow at the Center for Cosmology and Astroparticle Physics, suggests new insights into dark matter could be found by measuring its effect on the temperature of exoplanets.
