This image shows two spiral galaxies: NGC 4567 (left) and NGC 4568 (right). The color image was made from separate exposures taken in the visible and near-infrared regions of the spectrum with the FORS2 instrument on ESO’s Very Large Telescope. It is based on data obtained through four filters. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: ESO.

A pullout of the central region of the dwarf starburst galaxy Henize 2-10 traces an outflow, or bridge of hot gas 230 light-years long, connecting the galaxy’s massive black hole and a star-forming region. Hubble data on the velocity of the outflow from the black hole, as well as the age of the young stars, indicates a causal relationship between the two. A few million years ago, the outflow of hot gas slammed into the dense cloud of a stellar nursery and spread out, like water from a hose impacting a mound of dirt. Now clusters of young stars are aligned perpendicular to the outflow, revealing the path of its spread.
