How Do You Take a Picture of a Black Hole?
Quanta Magazine has published an explainer on how astronomers photograph black holes, a feat achieved through the Event Horizon Telescope, a network of radio observatories that combines data into a planet-sized virtual telescope. The article walks through how scientists turn faint radio signals from around the black hole's event horizon into the now-familiar images, starting with the first picture of M87 in 2019. Readers are discussing the imaging techniques and the physics involved.
Why now: Fresh Quanta coverage of black hole imaging has drawn attention from readers interested in astronomy and physics.
