And backing off a lot more, here is the core of the galaxy M87 photographed in infrared light (white) and visible light (blue). You can see the jet of hot gas shooting from the black hole at the center of the galaxy! It's about 5000 light years long. (continued)pic.twitter.com/GXHsf63SHb
A rotating disk of ionized gas surrounds this black hole. It's about 0.4 light years across, and moving at about 1000 kilometers/second. About 90 Earth masses of gas fall into this disk every day! Nobody knows what happens to matter after it falls into a black hole.pic.twitter.com/6vhxxDJmXe
What explains the daily variation? How can the ring vary on such a short time scale, anyway, if it is 0.4 light years across?
*Not* an answer to your question, but cool - from Wikipedia: "The Chandra X-ray Observatory has detected loops and rings in the gas [around the black hole in M87]. Their distribution suggests that minor eruptions occur every few million years." (cont)
Photographed, or radio data fitted via the use of a model of a black hole? I'm just asking....
"Photographed" was a bad choice of word - I was too excited, in too much of a rush. Here's a paper that explains exactly what was done: https://iopscience.iop.org/article/10.3847/2041-8213/ab0e85 …
A shame that Hawking didn’t live to see this!
