an illustration of an asteroid impacting the Earth

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 yellow octocoral

Algae called zooxanthellae live in the tissue of some sea animals, including many corals. The algae give the coral its color and also some food in exchange for shelter.
