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

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. Bouman explains how we can take a picture of the ultimate dark using the Event Horizon Telescope.

    (Katie) "building a telescope the size of the Earth is impossible"
