Fast-Spinning Brown Dwarfs May Reveal a Rotational Speed Limit

April 7, 2021

Using data from NASA’s Spitzer Space Telescope, scientists have identified the three fastest-spinning brown dwarfs ever found. More massive than most planets but not quite heavy enough to ignite like stars, brown dwarfs are cosmic in-betweeners. And though they aren’t as well known as stars and planets to most people, they are thought to number in the billions in our galaxy.
