Astronomers Spot a Possible Supernova Remnant Near the Milky Way's Supermassive Black Hole

NASAs Chandra X-ray Observatory and ESAs XMM-Newton may have found a supernova remnant near the supermassive black hole at the center of the Milky Way galaxy. If confirmed as a supernova remnant, the ejected material is moving at about two million miles per hour and is about 1,700 years old.
