Black holes are found in the centers of most galaxies, where they can influence star formation and the distribution of atoms in the environment surrounding them. However, direct observation of a black hole is difficult because it is so small relative to their masses. The Event Horizon Telescope (EHT) captured the first image ever taken of a black hole: specifically, the ring of light produced by matter just as it falls into the black hole at the center of the nearby galaxy M87. The EHT is a virtual observatory consisting of telescopes spanning the planet, from Greenland to the South Pole. The international collaboration operating the EHT includes observatories affiliated with the Center for Astrophysics | Harvard & Smithsonian: the CfA’s Submillimeter Array (SMA) and the Greenland Telescope.
