A massive asteroid hit the Earth 66 million years ago. The explosive collision rattled the planet and changed its climate. The devastating changes it triggered abruptly wiped out the dinosaurs — and most other living species.

A collapsar is a massive, spinning star that collapses into a black hole. That collapse releases a blast of light known as a long gamma-ray burst (illustrated). It also leads to an explosion in the star’s outer layers.
