The Oort Cloud May Be Much Stranger Than We First Thought

Right now, surrounding our entire solar system, there is a shell of frozen objects one trillion strong. Most of them have never moved. Some have been sitting still since before Earth existed. We call it the Oort Cloud. And for seventy-five years, scientists thought they understood it. A quiet, frozen bubble. Boring. They were wrong. It has spiral arms. It holds material from other stars. And the entire galaxy is slowly stirring it. We will visit a comet the size of Los Angeles already waking up far past Neptune, a world sitting in a region no planet can touch, and a discovery that happened by accident inside a planetarium.
