Einstein's theory of general relativity – the idea that gravity is matter warping spacetime – has withstood over 100 years of scrutiny and testing, including the newest test from the Event Horizon Telescope collaboration, published today in the latest issue of Physical Review Letters.  According to...

Analysis of the Event Horizon Telescope observations from 2009-2017 reveals turbulent evolution of the M87* black hole image

In 2019, the Event Horizon Telescope (EHT) Collaboration delivered ...

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 from the EHT data on the distant quasar 3C 279: they observed the finest detail ever seen in a jet produced by a supermassive black hole. New analyses, led by Jae-Young Kim from the Max Planck Institute for Radio Astronomy (MPIfR) in Bonn, enabled the collaboration to trace the jet back to its launch point,...

The global array of telescopes connected into the Event Horizon Telescope (EHT) was due to start observations at the end of March 2020 in order to expand and enhance the first set of results published approximately one year ago, including the first-ever image of a black hole in the galaxy M87. Regrettably, several participating...

The United States National Science Foundation (NSF) has announced the award of a $12.7M grant to architect and design a next-generation Event Horizon Telescope (ngEHT). The principal investigator of this program is the EHT Founding Director, Sheperd Doeleman at the Center for Astrophysics | Harvard & Smithsonian. The ngEHT will sharpen our focus on black holes, and let researchers move from still-imagery to real-time videos of space-time at the event horizon.

The new award is aimed at solving the formidable technical and algorithmic challenges required to...

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 makes scientists and engineers go to some of the most extreme environments on the Earth to collect data. On EHT social media pages, Twitter...
