This Earth-Sized Star Rotates Once Every 25 Seconds
Astronomers announced this week the discovery of the fastest-rotating white dwarf star on record, with a spin rate of once every 25 seconds. The star is about the size of Earth but, by the team’s measurements, contains least 200,000 times more mass, making the dense little object a spinning freak of nature.
