The Event Horizon Telescope (EHT) is a network of synchronized radio observatories around the world that combine as a single telescope with an aperture the size of Earth used to observe sources of radio light associated with black holes.

The Event Horizon Telescope is an international collaboration capturing images of black holes using a virtual Earth-sized telescope.

The Event Horizon Telescope (EHT) collects light from the black hole using a small number of telescopes distributed around the Earth. Once the EHT has measured data from the black hole, we still need to make a picture from it - a process referred to as imaging. The light we collect gives us some indication of the structure of the black hole.

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: the CfA’s Submillimeter Array (SMA) and the Greenland Telescope.

The Event Horizon Telescope (EHT) is an international collaboration that uses a global network of radio telescopes. Connecting multiple telescopes together in a technique known as interferometry enables them all to work together, forming one massive virtual telescope the size of the distance between them.
