Piston ZA Posted April 10, 2019 Share 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. stefmeister, Long Wheel Base, MTBeer and 3 others 6 Link to comment Share on other sites More sharing options...
Robbie Stewart Posted April 10, 2019 Share https://youtu.be/WdhQ5mM_Giw I just had a good laugh at this. Thanks Hairy. Hairy 1 Link to comment Share on other sites More sharing options...
Hairy Posted April 10, 2019 Share some of those are rather scary! I just had a good laugh at this. Thanks Hairy. Robbie Stewart 1 Link to comment Share on other sites More sharing options...

Piston ZA Posted April 11, 2019 Share 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 Hairy, Ed-Zulu, MTBeer and 8 others 11 Link to comment Share on other sites More sharing options...

Looks more like they used an old blackberry to take the shot. fanievb and Skylark 2 Link to comment Share on other sites More sharing options...
Piston ZA Posted April 11, 2019 Share 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....

Captain Fastbastard Mayhem Posted April 11, 2019 Share 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.... 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 DJR, Albatross, Spoke101 and 1 other 4 Link to comment Share on other sites More sharing options...
