Messier 51 (M51) system of galaxies: the main panel shows M51 in visible light data from NASA’s Hubble Space Telescope (red, green, and blue); the box at the top outlines the field of view by Chandra in the latest study, which focuses on the smaller component of M51, NGC 5195; the inset to the right shows the details of the Chandra data (blue) of this region. Dr Schlegel and co-authors found a pair of arcs in X-ray emission close to the center of NGC 5195, which they interpret as two outbursts from the galaxy’s supermassive black. They estimate that it took about one to three million years for the inner arc to reach its current position, and three to six million years for the outer arc.

The two streams crossing the image are jets of hot gas, ejected from the poles of a protostar. If the jets collide with the surrounding gas and dust they can clear vast spaces, and create curved shock waves, seen as knotted clumps called Herbig-Haro objects.

Blazars are the most common sources detected by NASA’s Fermi telescope. As matter falls toward a supermassive black hole at the galaxy’s center, some of it is accelerated outward at nearly the speed of light along jets pointed in opposite directions. When one of the jets happens to be aimed in the direction of Earth, as illustrated here, the galaxy appears especially bright and is classified as a blazar. Image credit: M. Weiss / CfA.
