Last year, astronomers observed two neutron stars collide. A crash in gravitational waves to detectors here on Earth. Represented in sound, you can hear a small upwards sweep in frequency, in the data, if you listen closely. Several seconds later, the first waves of electromagnetic radiation arrived here on Earth - the first time a collision has been detected by both light and gravitational waves. And it's in studying the electromagnetic of the collision that astrophysicists have gotten a far better of what really happened after those binary neutron stars merged, 130 million light years away. "Oh yeah, absolutely, so it gives us an understanding of all the nitty-gritty of what's going on after the merger takes place." Kunal Mooley, an astrophysicist at Caltech. First, he says, the stars collided, creating a massive, black hole like object, which started sucking up the cloud of neutron-rich cosmic debris left over from the crash. But its was limited.
