Watch Two Neutron Stars Collide 130 Million Light Years Away

Newsweek - Astrophysicists have reconstructed the collision of two neutron stars 130 million light years away using gamma-rays, x-rays and radio emissions.

"That simple model—of a jet with no structure (a so-called top-hat jet) seen off-axis—would have the radio and X-ray emission slowly getting weaker. As we watched the radio emission strengthening, we realized that the explanation required a different model," said co-author Alessandra Corsi, of Texas Tech University.

After probing the data, researchers came up with a cocoon-shaped model instead.

As you can see in the video above, a high-speed jet is choked as it shoots from the collision, before it breaks into a round cocoon of radio waves, gamma rays and x-rays.
