Gravitational waves from white-dwarf pair

Gravitational waves spotted from white-dwarf pair

Researchers have spotted visible-light evidence for one of astronomy's most elusive targets - gravitational waves - in the orbit of a pair of dead stars.

Until now, these ripples in space-time, first predicted by Einstein, have only been inferred from radio-wave sources.

But a change in the orbits of two white dwarf stars orbiting one another 3,000 light-years away is further proof of the waves that can literally be seen.

A study to be reported in Astrophysical Journal Letters describes the pair.
