- Astronomers find biggest super-puff planets yet that are lighter than cotton candy
Astronomers discovered two super-puff planets orbiting a star 1,110 light-years away in the constellation Volans. The planets, the largest exoplanets found with a density lower than cotton candy, are likely composed of hydrogen and helium. The study was led by George Dransfield from the University of Oxford and published in the Monthly Notices of the Royal Astronomical Society.
