The Black Hole Files with Camille Carlisle

How Does the Event Horizon Telescope Work?

The Event Horizon Telescope creates the image of a black hole shadow thanks to the precise coordination of a worldwide telescope network. Here’s how they do it.

Could Dark Matter Be Black Holes?

Astronomers are reconsidering primordial black holes as an answer to the invisible matter mystery, but recent observations disfavor at least some sizes of black hole.

Piercing the Veil of Our Black Hole

Astronomers have overcome the interference of clumpy interstellar gas to catch a glimpse of the gas around the Milky Way’s central black hole.
