Scientists might reveal the first photo of our galaxy's central black hole on Thursday. Watch their announcement live.

The scientists who revealed the first image of a black hole have a big announcement to make on Thursday.

They won't say what they found. After the snapshot of the first black hole, which was located in another galaxy, the collaboration began working toward capturing imagery of the supermassive black hole at the center of the Milky Way. It is possible that they will reveal the first-ever picture of our black hole, Sagittarius A*, which has the mass of 4 million suns.

In a press release, the National Science Foundation teased a "groundbreaking Milky Way discovery" by the black-hole-hunting collaboration. At least seven research institutions across the planet will hold simultaneous press conferences to announce a discovery on Thursday at 9 a.m. Time.

You can watch the announcement live in the video.

Sagittarius A* has never been captured in detail. The Chandra telescope has not spotted the bright X-rays around the black hole.

It's impossible to get a clear close-up image of a black hole with an individual telescope. The EHT researchers solved the problem by linking telescopes across the planet to focus on the same object, creating a virtual observatory the size of Earth.

Shep Doeleman, an astronomer at Harvard University and founding director of the EHT collaboration, told Insider that the group was focusing its attention on Sagittarius A*, as well as branching into a separate project, called next-generation EHT, to create the first video footage of.

The group would need to add more telescopes and use new computer technology to process more data from them. He estimated that they could capture video of Sagittarius A* and their original photo subject in about five years.

It is too early for video, but possibly early enough for a clear image.

Ahead of the announcement, a representative for EHT declined to give further details.

Videos would shed new light on how black holes eat

Video could show how black holes matter.

The black hole can evolve in real time and we can understand how it launches its jets. We can see how it evolved. We can look at the matter around the black hole in a completely different way.

The first videos will probably be rudimentary, but further upgrades would allow EHT to capture the black holes in more and more detail.

They might be a little too fast. They might be low-resolution, but they would be the first step. That will allow us to make high-fidelity movies.
