Photographing A Supermassive Black Hole With The Event Horizon Telescope

Michael D. Johnson
Harvard-Smithsonian Center for Astrophysics

Black holes are so dense that not even light can escape. But, through their immense gravitational pull, they also power the brightest and most efficient engines in the universe, lighting up the centers of galaxies where supermassive black holes dwell. Black holes are predicted to cast a shadow on their bright surrounding material, but no observation to date has had the angular resolution required to view a black hole directly and test this prediction. Dr. Johnson will describe the quest to complete the Event Horizon Telescope—an Earth-sized instrument with resolving power thousands of times finer than the Hubble Space Telescope—and to take the first picture of a black hole, putting Einstein's theory to the ultimate test.
