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…
