  • The Event Horizon Telescope Collaboration (EHTC) welcomes critical, independent analysis and interpretation of our published results. We publish detailed descriptions of our methods as well as raw data, data products, and analysis scripts to facilitate transparency, rigor, and reproducibility.

    The EHT images of M87 are among the most vetted interferometric images ever published (1,2). Four independent analyses (3,4,5,6) have reconstructed the ring-like structure of M87, employing a diverse set of techniques.  These efforts complement the three...

  • Astronomers have unveiled the first image of the supermassive black hole at the centre of our own Milky Way galaxy. This result provides overwhelming evidence that the object is indeed a black hole and yields valuable clues about the workings of such giants, which are thought to reside at the centre of most galaxies. The image was produced by a global research team called the Event Horizon Telescope (EHT) Collaboration, using observations from a worldwide network of radio telescopes.

    The image is a long-anticipated look at the massive object that sits at the...

  • The Event Horizon Telescope Collaboration (EHTC) and Joint ALMA Observatory (JAO) announce the public data release of the Very Long Baseline Interferometry (VLBI) 1-mm observations by the Event Horizon Telescope (EHT) in April 2017. The overall goal of the observations is to image the supermassive black holes M 87* and Sagittarius A* at event horizon scales and to image the AGNs OJ 287, 3C 279, Centaurus A, and NGC 1052 at high resolution.

    Public release data packages are available from...

  • An international team anchored by the Event Horizon Telescope (EHT) Collaboration, which is known for capturing the first image of a black hole in the galaxy Messier 87, has now imaged the heart of the nearby radio galaxy Centaurus A in unprecedented detail. The astronomers pinpoint the location of the central supermassive black hole and reveal how a gigantic jet is being born. Most remarkably, only the outer edges of the jet seem to emit radiation, which challenges our theoretical models of jets. This work, led by Michael Janssen from the...

  • The Event Horizon Telescope (EHT) collaboration, who produced the first ever image of a black hole, has revealed today a new view of the massive object at the centre of the M87 galaxy: how it looks in polarised light. This is the first time astronomers have been able to measure polarisation, a signature of magnetic fields, this close to the edge of a black hole. The observations are key to explaining how the M87 galaxy, located 55 million light-years away, is able to launch energetic jets from its core.

  • Recognizing their vision and leadership within the Event Horizon Telescope (EHT), the National Academy of Sciences (NAS) awards Shep Doeleman and Heino Falcke the Henry Draper Medal.  The 300+ members of the collaboration are honored and proud of this recognition of the revolutionary and fundamental scientific results they achieved together.

    The Henry Draper Medal is awarded every four years and honors a recent, original investigation in astronomical physics of sufficient importance and benefit to science.  From the NAS: "the...

  • 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 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...
