AI Insight
Astronomers have discovered two exceptionally low-density exoplanets, termed "super-puffs," that are comparable in size to Jupiter but have densities lower than cotton candy. These planets represent the largest examples of this rare class of ultra-low-density worlds found to date. Their extremely puffy nature challenges current models of planetary formation and atmospheric retention.
Why it matters
The discovery of these extreme super-puffs provides crucial data for understanding how planets can maintain such low densities and expanded atmospheres. These findings will help refine theoretical models of planetary evolution and atmospheric dynamics in young planetary systems.
Understand the Science
Astronomers have uncovered a pair of giant planets that are lighter than cotton candy—super-puffs the size of Jupiter.
