With the help of two radio telescopes coordinated by the UA, astronomers in the Event Horizon Telescope collaboration have taken the first direct image of a black hole, a prediction of Einstein's General Theory of Relativity.

A worldwide collaboration will work on ways of processing unprecedented amounts of data in real time, with a primary goal of assisting the effort to take the first-ever pictures of a black hole. However, applications eventually could include self-driving cars, renewable energy and national defense.

Adding Antarctica's largest astronomical telescope to the Event Horizon Telescope, a UA-led collaboration of astronomers has come closer to taking detailed images of the supermassive black hole in the center of the Milky Way, up to its very edge, the "event horizon."

The discovery of the brightest quasar in the early universe, powered by the most massive black hole yet known at that time, presents a puzzle to researchers.

If you go see the movie "Interstellar," know this: UA astrophysicists are working on something much more impressive, the first pictures of an actual black hole lurking at the center of the Milky Way.
