On April 10, 2019, the team announced their results: They had successfully imaged the supermassive black hole in the center of the galaxy m87, which is nearly 54 million light-years away from us. They were able to achieve unprecedented resolution using very long baseline interferometry, which combines the observations of multiple radio telescopes across the globe.

The team wanted to find out whether Einstein's Theory of General Relativity holds up in the extreme environment of black holes, and the results do, in fact, seem to be consistent with the predictions. In the future, we may see more and shaper images of black holes as the team targets smaller wavelengths of light and recruits more telescopes. Eventually, they may include an orbiting space telescope..."
