Astronomers have cracked the case of a mysterious repeating radio signal that has been a mystery since it was uncovered last year .

The team tracked the signal back to a strange binary system containing a dead star or "white dwarf" and a red dwarf stellar companion.

Previously, long-period radio bursts like this one had only been traced back to neutron stars.

This work puts an entirely new spin on their origins.
