Sgr A*, pronounced sadge-ay-star, is a complex radio source at the center of the Milky Way Galaxy, and is home to a supermassive black hole, or SMBH. More than 300 researchers from 80 institutions around the world worked together to image SgrA* using the Event Horizon Telescope (EHT), a global telescope made up of multiple radio arrays working together. Visually, SgrA* looks a lot like M87*, the first black hole ever imaged. But, the new results have shown that they're as different as can be.
