Building a better black hole with supercomputer simulations

Astronomers used a perhaps unlikely tool to understand what they saw in their first historic image of the Milky Way’s supermassive black hole: a library of computer simulations that mimic the black hole with millions of variations.

Taking an image of a dungeonWhat Sagittarius A* in the center of our galaxy, with the event horizon telescope (EHT) is one of the most complicated feats any astronomer will ever undertake. the new image combines petabytes of data from eight radio telescopes around the world; Then advanced computer algorithms go to work converting all this disparate data into a false color image.
