Story Highlights

The Event Horizon Telescope shared the first image of Sagittarius A*, the supermassive black hole at the center of the Milky Way.

The view past the clouds of gas and dust — confirmed with the help of the Frontera supercomputer at The University of Texas at Austin — revealed a black hole that is hot, dense, and quickly changing, with a ring of superheated gas around its dark center.

The EHT team's results were published today in a special issue of The Astrophysical Journal Letters. The analysis in paper five utilized nearly 80 million CPU hours on Frontera.
