April 10, 2019, Event Horizon Telescope (EHT) collaboration

On April 10, 2019, the Event Horizon Telescope (EHT) collaboration announced that it had photographed the contours of the supermassive black hole at the heart of M87, a huge elliptical galaxy the mass of 6.5 billion suns, that lies 55 million light-years from Earth. The epic achievement further bolsters Einstein’s theory of general relativity, which describes gravity as a consequence of the warping of space-time.
