This image of the galaxy cluster MACS J0416 combines data from three telescopes - Hubble (showing the galaxies and stars), Chandra (diffuse emission in blue), and the Jansky Very Large Array (diffuse emission in pink). MACS J0416 acts as a powerful natural lens by bending and magnifying the light of far-more-distant objects behind it. Image credit: NASA / ESA / CXC / NRAO / AUI / NSF / STScI / G.

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.
