Swift Sees Changes in the Milky Way 2006 - 2013

This sequence from the X-ray Telescope aboard NASA's Swift shows changes in the central region of the Milky Way galaxy from 2006 through 2013. Watch for flares from binary systems containing a neutron star or black hole and the changing brightness of Sgr A* (center), the galaxy's monster black hole. Credit: NASA/Swift/N.
