The Event Horizon Telescope is a global network of synchronized radio observatories that work in unison to observe radio sources associated with black holes with angular resolution comparable to their event horizons. The required extreme resolving power...
Scientists of the EHT and their collaborators try to organize observations with a number of different telescopes so that they coincide with observations with EHT observations. The aim of this is to provide multi-wavelength coverage in order to...
First Event Horizon Telescope Images of a Black-Hole Powered Jet One year ago, the Event Horizon Telescope (EHT) Collaboration published the first image of a black hole in the nearby radio galaxy M 87. Now the collaboration has extracted new information...
SXSW 2019 Panel -- Event Horizon Telescope: A Planetary Effort to Photograph a Black Hole Predicted almost a century ago by Einstein’s Theory of General Relativity, black holes not only exist, but actually power some of the most extreme phenomena in the...
The Event Horizon Telescope (EHT) collaboration is pleased to have been granted by the Royal Astronomical Society (RAS) the 2021 Group Achievement Award (A). The EHT is a global network of synchronised radio observatories that work in unison to observe...
The Event Horizon Telescope needs your help! We have put together a proposal for a panel to be featured at the 2019 South by Southwest (SXSW) festival in Austin, Texas, March 8-17 2019. Over 5,000 panels have been submitted to SXSW, but fewer than 1,000...
Latest Results The latest results from the Event Horizon Telescope (EHT) Collaboration were published on Feb 8th 2023. Astronomers Reveal First Image of the Black Hole at the Heart of Our Galaxy On May 12th 2022, the EHT Collaboration presented the first...
We present Event Horizon Telescope (EHT) 1.3 mm measurements of the radio source located at the position of the supermassive black hole Sagittarius A* (Sgr A*), collected during the 2017 April 5-11 campaign. The observations were carried out with eight...
A new image from the Event Horizon Telescope (EHT) collaboration has uncovered strong and organized magnetic fields spiraling from the edge of the supermassive black hole Sagittarius A* (Sgr A*). Seen in polarized light for the first time, this new view...
In 2022, the Event Horizon Telescope Collaboration (EHTC) published the first image of the black hole in the Milky Way Galactic Center, Sagittarius A* (Sgr A*; 1). The image shows a ring-like structure with a central depression, consistent with the...
The black hole images obtained with the Event Horizon Telescope (EHT) are expected to be variable at the dynamical timescale near their horizons. For the black hole at the center of the M87 galaxy, this timescale (5–61 days) is comparable to the 6 day...
