[NASA] Black Hole Image Makes History; NASA Telescopes Coordinated Observations

Update:

Previous title for this thread: [PHYS] (UPDATE) Scientists set to unveil first picture of a black hole

As an ongoing news event I have updated the title and added more info.





Quote:
The stunning new image shows the shadow of the supermassive black hole in the center of Messier 87 (M87), an elliptical galaxy some 55 million light-years from Earth. This black hole is 6.5 billion times the mass of the Sun. Catching its shadow involved eight ground-based radio telescopes around the globe, operating together as if they were one telescope the size of our entire planet.

“This is an amazing accomplishment by the EHT team,” said Paul Hertz, director of the astrophysics division at NASA Headquarters in Washington. “Years ago, we thought we would have to build a very large space telescope to image a black hole. By getting radio telescopes around the world to work in concert like one instrument, the EHT team achieved this, decades ahead of time.”

Quote:
The world, it seems, is soon to see the first picture of a black hole.

On Wednesday, astronomers across the globe will hold "six major press conferences" simultaneously to announce the first results of the Event Horizon Telescope (EHT), which was designed precisely for that purpose.
It has been a long wait.


Quote:
The Event Horizon Telescope is an international collaboration that aims to capture images of black hole areas by linking up various radio dishes from around the world that together create a virtual telescope roughly the size of planet Earth. The project began capturing data in 2006.

Quote:
Photographing actual black holes is impossible. Their gravity keeps anything from escaping, including X-rays, infrared, light and radio waves, according to Science Alert. So there's nothing for our cameras to capture.
Instead, scientists are aiming for images of the event horizon, the precipice of the black hole known as the "point of no return," and the gas and dust that settles into orbit around the hole, according to Science News.

This is going to be an a huge news event covered from everywhere, so I quoted parts from 3 different articles/sources.

Posted below is some background info on this whole project. One of the most interesting aspects about this is the supercomputing they had to do.

I'm expecting it to be very pixelated or low-res. Or it could be as good as those images of the pillars of creation.

I'm expecting the same old black dot with an infrared image around it.

Pretty sure there will not just be an image, but also a short video. 64gb's per second of data per telescope, 12 telescopes. That's 768gb's of data per second's worth of data.

I'm sure it will be a pretty picture that people will get sucked into.

thought they already released an image of it.


4:13 mark is where the actual image shows up.

Maybe that one is just the results of the first pass on super sampling or whatever the method is of merging the data or something.

sooo the stuff from a couple years ago was what? interpolated data, instead of actual lenses? I r confuse.

I'm sub'd to his channel. I thought it was going to be something like 3:20 but I didn't watch that vid yet.

I'm sure there will be more than just an image though. Public interest is what keeps scientific funding going so I'd guess they'll have some graphics/video of it.
