Increased X-Ray Activity From Milky Way's Supermassive Black Hole Puzzles Astronomers

An X-ray view (at the bottom) of the region around Sgr A*, the supermassive black hole at the center of the Milky Way galaxy, taken with NASA’s Chandra X-ray Observatory. The analysis of archival observations from Chandra and other orbiting X-ray telescopes has revealed that Sgr A* has increased its X-ray flaring by […]
