Just 7,800 light-years from Earth, two dead stars have been discovered orbiting each other at record-breaking speeds. So close is their orbit, that astronomers expect to detect gravitational waves from this pair in a matter of years, when we turn on more sensitive tools.

We're used to things on cosmic scales happening pretty slowly, but the white dwarf binary - named ZTF J1539+5027, or J1539 for short - has an orbital period of just 6.91 minutes, the shortest ever detected for an eclipsing binary. That's such a close orbit, the entire binary system could fit inside Saturn.
