A Tour of SDSS J103842.59+484917.7
One hundred years ago this month, Albert Einstein published his theory of general relativity, one of the most important scientific achievements in the last century. (2015-11-24)

M82 in 60 Seconds

Narrator (Megan Watzke, CXC): We begin with a composite image of the nearby starburst galaxy M82 that contains X-rays from Chandra in blue, optical data from Hubble in green and orange, and infrared data from Spitzer in red. Next we zoom into the central region of M82, where just Chandra's view is visible. There we see two bright X-ray sources of special interest. Astronomers think these may be medium-sized black holes. These "survivor" black holes seem to have avoided falling into the center of the galaxy. They could also be examples of seeds required for the growth of supermassive black holes in all galaxies, including the one in the Milky Way.
