This artist’s impression shows our Milky Way Galaxy as it may have appeared 6 million years ago during a phase of quasar-like activity. Outside of that bubble, a pervasive ‘fog’ of million-degree gas might account for the galaxy’s missing matter of 130 billion solar masses. Image credit: Mark A. Garlick / CfA.

Blazars are the most common sources detected by NASA’s Fermi Gamma-ray Space Telescope. As matter falls toward the 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.

An artist’s rendition of the Akira (right) and Tetsuo (left) galaxies in action. Akira’s gravity pulls Tetsuo’s gas into its central supermassive black hole, fueling winds that have the power to heat Akira’s gas. Because of the action of the black hole winds, Tetsuo’s donated gas is rendered inert, preventing a new cycle of star formation in the Akira galaxy. Image credit: Kavli IPMU.

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.
