Origins & Early Life

The Event Horizon Telescope (EHT) is a telescope array consisting of a global network of radio telescopes. The EHT project combines data from several very-long-baseline interferometry (VLBI) stations around Earth, which form a combined array with an angular resolution sufficient to observe objects the size of a supermassive black hole's event horizon.

Career & Major Achievements

The project's observational targets include the two black holes with the largest angular diameter as observed from Earth: the black hole at the center of the supergiant elliptical galaxy Messier 87, and Sagittarius A*, at the center of the Milky Way. The Event Horizon Telescope project is an international collaboration that was launched in 2009 after a long period of theoretical and technical developments.

Enduring Legacy & Impact

On the theory side, work on the photon orbit and first simulations of what a black hole would look like progressed to predictions of VLBI imaging for the Galactic Center black hole, Sgr A*. Technical advances in radio observing moved from the first detection of Sgr A*, through VLBI at progressively shorter wavelengths, ultimately leading to detection of horizon scale structure in both Sgr A* and M87.

Historical Fact-Check Quiz: Event Horizon Telescope

True or False: “The Event Horizon Telescope was designed to image the accretion disk of a supermassive black hole using visible light wavelengths.”

Answer (FALSE ❌): The EHT is a radio telescope array, meaning it observes electromagnetic radiation at radio wavelengths, not visible light. This allows it to penetrate dust clouds and image structures near the event horizon.
