Media Advisory: First Results from the Event Horizon Telescope to be Presented on April 10th April 1, 2019
On April 10th 2019, the Event Horizon Telescope (EHT) Collaboration will present its first results in multiple simultaneous press conferences around the world, and many satellite events organized by its stakeholder and affiliated institutions. Press conferences will be held simultaneously in Brussels (in English), Lyngby (in Danish), Santiago (in Spanish), Shanghai (in Mandarin), Tokyo (in Japanese), Taipei (in Mandarin), and Washington D.C. (in English), starting at 13:00 Universal Time.
For more details regarding particular press events, please follow the links below:
Brussels: media advisory from the European Research Council, European Southern Observatory, and Max Planck Institute for Radio Astronomy Lyngby: media advisory from Greenland Telescope Denmark Santiago: media advisory from the ALMA Observatory Shanghai: media advisory from the Shanghai Astronomical Observatory, Chinese Academy of Sciences Taipei: media advisory from the Institute of Astronomy and Astrophysics, Academia Sinica Washington D.C.: media advisory from the National Science Foundation Major press conferences will be streamed live online via the following channels:
Brussels: European Comission Youtube Channel Santiago: ALMA website and social networks (Facebook, Twitter, Youtube). Taipei: Academia Sinica channels on Youtube and Facebook Tokyo: National Astronomical Observatory of Japan channels on Youtube and Niconico Washngton: National Science Foundation Live Stream
An EHT press release will be publicly issued shortly after the start of the press conferences on April 10th. Translations of the press release will be available in multiple languages from the EHT and our partner institutions, along with extensive supporting audiovisual material. Background material describing various aspects of the Event Horizon Telescope is available on this website and partner websites listed below. Additional material will be made available closer to the press release, and listed here. Please follow our updates on social media, on Twitter (@ehtelescope, #EHTblackhole), Facebook (@ehtelescope), and Youtube channel.

The Event Horizon Telescope may soon release first-ever black hole image A photo of the Milky Way's central black hole, Sagittarius A*, would be the first of its kind.
By Korey Haynes | Published: Tuesday, April 2, 2019 RELATED TOPICS: BLACK HOLES | GALAXIES blackhole While still a simulation for now, the Event Horizon Telescope has promised to image a black hole, and they’re poised to make a big announcement. Hotaka Shiokawa No, you can’t actually take a picture of a black hole. But astronomers have promised to do the next best thing: To image the seething chaos just outside the black hole, known as its event horizon. To capture this region, just on the cusp of the black hole itself, astronomers have had to link telescopes from across the globe and focus them on the closest, most massive black holes known: Sagittarius A* (pronounced “A-star”), which resides at the center of our own Milky Way galaxy, as well as the even larger supermassive black hole that sits at the center of nearby galaxy M87.
The result, known as the Event Horizon Telescope (EHT) had its big observing run in April of 2017. Researchers warned that it would take time to piece together the data. And the team has repeatedly dropped hints that the results could be ready soon, only for the project to continue on. But based on their upcoming press event, set for April 10, it seems that time may have come, and that viewers are about to see the first-ever picture of a black hole’s event horizon.
Teamwork EHT is actually a team of telescopes working together in a process known as interferometry. This lets the connected telescopes behave as if they had one enormous collecting area. Of course, there are gaps between the individual observatories, and each telescope is unique and behaves in slightly different ways – as well as experiencing different weather, and having a different view of the black hole, though this last is actually the feature that makes the combined imaging so accurate. But figuring out how to stitch all that data together is why researchers have taken so long to turn the 2017 data into a presentable image.
But the cooperation pays off. Individually, the telescopes are world-class. And together, they deliver enough observing power that a person standing in New York City could use the EHT to read the writing on a quarter in Los Angeles, something none of them could do individually.
It’s not clear which of the black holes targeted by EHT may be ready to show off to the public. It’s also not for certain that they’ve actually accomplished the feat yet. But after such a wait, the pictures should be stunning. The National Science Foundation, which helps fund EHT, will be hosting the press conference. Due to the collaboration being spread across the globe, other press conferences will happen simultaneously in Brussels, Santiago, Shanghai, Taipei and Tokyo, highlighting the cooperation and vast resources it takes to make a project this large succeed.
The announcement will be livestreamed at the NSF’s webpage.

^ Yes. Exciting that Einstein continues to be right. At some point it seems to me that we're gonna halve to stop calling Einstein's General Relativity a theory.

As for “theory,” though, scientists use the term to mean something that is different from how it’s been corrupted into general use. There are countless scientific “theories” that have been demonstrated to be true beyond any reasonable doubt.

I guess it’s an ok picture, given that it’s about 54.5 million light years away. The image we see is how it looked at roughly the time the dinosaurs went instinct...

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Yeah...exactly! I was wondering how long it took for that light to reach the telescope cameras. Just amazing stuff...

Sounds like their basically stacking images from different scopes. I do some astrophotography and use stacking software, amazing how a lot of poor images, when stacked, create a much better image.

I particularly like the "theories" of mathematics. And gravity.

Not if we zoom in!

The really remarkable thing about that image is that it was acquired with ground-based telescopes. Telecopes that have to contend with the Earth's atmosphere have much tougher time resolving such images, when compared to space-based telescopes.
