Jupiter-sized giant planets but lighter than candy floss: Researchers at Oxford and Birmingham universities discover super-puff planets TOI-791 b and TOI-791 c; here's how far they are from Earth, their densities, how they formed, and why they are so rare

Astronomers have discovered two 'super-puff' giant planets, TOI-791 b and TOI-791 c, boasting densities lower than candy floss. Orbiting a star 1,110 light-years away, these Jupiter-sized worlds are remarkably diffuse, offering scientists a unique opportunity to study planetary formation. Their existence challenges current models, prompting further investigation into how such low-density gas giants come to be.
