Katie Bouman: How to take a picture of a black hole

12:51 minutes · Filmed Nov 2016 · Posted Apr 2017 · TEDxBeaconStreet

At the heart of the Milky Way, there's a supermassive black hole that feeds off a spinning disk of hot gas, sucking up anything that ventures too close -- even light. We can't see it, but its event horizon casts a shadow, and an image of that shadow could help answer some important questions about the universe. Scientists used to think that making such an image would require a telescope the size of Earth -- until Katie Bouman and a team of astronomers came up with a clever alternative. Learn more about how we can see in the ultimate dark.
