Piston ZA Posted April 10, 2019 Posted April 10, 2019 This is pretty exciting I think. Love all the space stuff. Just wish I was intelligent enough to really understand it. https://www.news24.com/Green/News/scientists-set-to-reveal-first-true-image-of-black-hole-20190410Here it is... https://www.nasa.gov/mission_pages/chandra/news/black-hole-image-makes-history A black hole and its shadow have been captured in an image for the first time, a historic feat by an international network of radio telescopes called the Event Horizon Telescope (EHT).A black hole is an extremely dense object from which no light can escape. Anything that comes within a black hole’s “event horizon,” its point of no return, will be consumed, never to re-emerge, because of the black hole’s unimaginably strong gravity. By its very nature, a black hole cannot be seen, but the hot disk of material that encircles it shines bright. Against a bright backdrop, such as this disk, a black hole appears to cast a shadow. 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.

Hairy Posted April 10, 2019 Posted April 10, 2019 some of those are rather scary! I just had a good laugh at this. Thanks Hairy. Robbie Stewart 1
Piston ZA Posted April 11, 2019 Posted April 11, 2019 Just a little more on the black hole photo, I don't think enough people realise the significance of the image, and how difficult it is to photograph. Here is a TED Talk from over a year ago by Dr Katie Bouman, one of the members of the team, who created the algorithm making the image possible, explaining it in more detail. It's truly fascinating stuff https://www.youtube.com/watch?v=BIvezCVcsYs Eddy Gordo, Kalahari Vegmot, Ed-Zulu and 8 others 11

Looks more like they used an old blackberry to take the shot. fanievb and Skylark 2
Piston ZA Posted April 11, 2019 Posted April 11, 2019 Looks more like they used an old blackberry to take the shot.It's an image from 55 million light years away (the equivalent of photographing an orange on the face of the moon), of something that by definition cannot be seen.... Hairy 1

Well, it's not the hole itself we're seeing... It's all the **** and light around the black hole. Plus, here's the full pic. We've only been seeing a small portion of it in the media. Which is also why it's so grainy. Edited April 11, 2019 by Captain Fatbastard Mayhem Piston ZA, Albatross, DJR and 1 other 4
