>> For the first time, scientists have observed the results of two stars crashing into each other. A cosmic collision ushering in a new chapter in astronomy. The two neutron stars collided some 130 million years ago, creating both light and gravitational waves. The ripples in space and time first predicted by Albert Einstein.

>> Over a century ago, Einstein predicted that two orbiting objects will emit gravitational waves as they spiral in. And astrophysicists predicted that as the two compact objects, especially neutron stars, collide they should emit gamma rays in jets. And a cascade of light across the whole electromagnetic spectrum was predicted.

>> The crash also explains where gold may have come from.>> This is my great grandfather's gold watch. It's about a hundred years old. The gold in this watch was very likely produced in the collision of two neutron stars. So this is really an amazing discovery.>> The crash was first detected in August by gravity wave machines at LIGO laboratories in Louisiana and Washington State.

As well as the third detector, named Virgo, in Italy. The National Science Foundation, an independent agency of the US government, provided about $1.1 billion in funding for the LIGO research over 40 years.
