Cotton candy … planets? These “super-puffs,” discovered by our @NASAExoplanets Kepler telescope, look as big as Jupiter but are roughly a hundred times lighter in mass. Like real cotton candy, their puffy atmospheres won’t last forever: https://go.nasa.gov/3WhgZi3 #CottonCandyDay #NASAUniverse
"Super-Puffs" may sound like a new breakfast cereal. But it's actually the nickname for a unique and rare class of young exoplanets that have the density of cotton candy. Nothing like them exists in our solar system.
