Scientists gear up to take a picture of a black hole

On Wednesday, Jan. 18, astronomers, physicists and scientists from related fields will convene in Tucson, Ariz. from across the world to discuss an endeavor that only a few years ago would have been regarded as nothing less than outrageous. The conference is organized by Dimitrios Psaltis, an associate professor of astrophysics at the University of Arizona's Steward Observatory, and Daniel Marrone, an assistant professor of astronomy at Steward Observatory.
