I also want to point out that the mass around Sagittarius A* is rapidly shifting which makes getting a sharp image still harder. From the NYT:
Sagittarius A*, the black hole in the Milky Way galaxy, is a harder target. It is less than one-thousandth the mass and size of the M87 hole and, therefore, evolves a thousand times faster. The M87 black hole barely budges during a weeklong observing run, but Sagittarius A* changes its appearance as often as every five minutes.

- bjelkeman-again 4y agoM87, according to the original link is 1000x the mass of Sag A, which has a diameter 17x that of our sun. It is mind (and space) bending.
- JohnBooty 4y agoWow, that's incredible. Is that because of all the material the black hole is "devouring?"

- brandmeyer 4y ago> all while compiling an unprecedented library of simulated black holes to compare with the observations It also sounds like this is the combination of an image-generating model hypothesis as well as the raw data itself. Ie, this is the image that the model produces which best-fits the sparse interferometry data.
