Astronomers have discovered two exoplanets with extremely low densities, compared to cotton candy, according to ScienceDaily.
The so-called super-puff planets are notable for being remarkably light for their size, a rarity that interests researchers studying planetary formation. Such low-density worlds challenge typical expectations about how planets are structured.
The discovery adds to the catalog of unusual exoplanets. Its findings reflect the astronomers’ observations of the two bodies.
