A Tour of Eta Carinae
A Tour of Eta Carinae
New Chandra data are helping astronomers better understand how the two stars in Eta Carinae interact with one another through powerful winds blowing off their surfaces. (2014-08-27)


M82 in 60 Seconds

View/Listen
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.
