Two ‘super-puff’ planets are as wispy as cotton candy

Astronomers have discovered two planets, TOI-791 b and TOI-791 c, that are remarkably low in density, earning them the nickname "super-puff." Despite being around the size of Jupiter, these planets are astonishingly light, with densities 28–35 times less than water. This discovery sheds light on the diversity of planetary formations in our galaxy and challenges our understanding of planet structure and composition. Such findings are crucial for advancing our knowledge of exoplanets and their potential atmospheres.
