The two black holes that sent out ripples in space and time as they merged were born in the belly of a giant star, new research suggests.*

The*Laser Interferometer Gravitational-wave Observatory (LIGO) caught sight of the two black holes colliding on Sept. 14, 2015, by detecting the gravitational waves — ripples in space-time — sent out by the merger.

At about the same time as the merger, the*Fermi Space Telescope caught sight of a bright burst coming from the same part of the sky as the black holes.*

Gravitational waves are thought to be "dark" events, so finding any kind of bright burst associated with them is surprising, scientists say; however, researchers think they've found some kind of explanation for the burst.* Read more...
