The First Neutron Star Collision We've Ever Seen

The video discusses the first observed collision of neutron stars, detected by LIGO, which confirmed theories about gravitational waves, kilonovas, and the formation of heavy elements. The event provided insights into neutron stars and their collisions, producing a kilonova and gamma-ray burst. It also highlighted the role of neutron star mergers in creating heavy elements like gold. The video concludes with a mention of Brilliant.org's astronomy lessons.
