Two dead stars have been spotted whipping around each other every seven minutes. The newfound dynamic duo, officially known as ZTF J1539+5027, is the second-fastest pair of orbiting dead stars, called white dwarfs, yet discovered. 

The pair, located nearly 8,000 light-years away in the Boötes constellation, is also the fastest eclipsing binary system, meaning that one white dwarf repeatedly crosses in front of the other from our point of view.
