An exoplanet found orbiting a red dwarf star turns out to have the density of a marshmallow, surprising researchers who didn’t expect a planet with an atmosphere that close to an active star.

The planet, named TOI-3757 b, is the fluffiest gas giant planet ever discovered around this type of star. CREDIT: NOIRLab/NSF/AURA/J. da Silva/Spaceengine/M. Zamani
