When Stars Collide: LIGO Detects Gravitational Waves from ‘Kilonova’ Light Show

In the galaxy NGC 4993, located approximately 130 million light-years from Earth, two neutron stars collided. And, for the first time, scientists detected the gravitational waves to prove it. They may have even solved the long-standing mystery about the origin of gold and platinum.
