Sagittarius A* is the supermassive black hole at the center of the Milky Way. As supermassive black holes go, it is fairly quiet. It’s not creating any galaxy-wide tantrums that should worry us.

NEW YORK (AP) — Scientists have spotted what appear to be two stars whipping around each other near the supermassive black hole at the center of our Milky Way galaxy. Nearly every large galaxy ...

The supermassive black hole at the center of the Milky Way, called Sagittarius A*, is about four times more massive than this one. White dwarfs are among the most compact objects in the cosmos ...
