This composite image shows the starburst galaxy Messier 82. The magnetic field detected by SOFIA, shown as streamlines, appears to follow the bipolar outflows (red) generated by the intense nuclear starburst. The image combines visible starlight (gray) and a tracing of hydrogen gas (red) from the Kitt Peak Observatory, with near-infrared and mid-infrared starlight and dust (yellow) from SOFIA and NASA’s Spitzer Space Telescope.

The location of the FRB 150807. The yellow circle shows the typical location of an FRB. There are thousands of stars and galaxies in this direction. Because FRB 150807 was very bright the astronomers were able to locate it to a small region near the edge of that circle, shown as the pink banana-shaped region in the inset. In this region there are only six detected galaxies. The position of the most likely host galaxy, VHS7, is highlighted on the plot.

Using the Cosmic Web Imager (CWI) to study a system with two quasars 10 billion light-years away, the astronomers have unveiled a protogalaxy being fed cool gas by a filament of the cosmic web. The quasar UM 287 is the larger object at right; the newly-discovered protogalaxy is above and to the left of UM 287. This picture combines a visible light image of the system with CWI data; a filament of the cosmic web can be seen funneling cold gas onto the protogalaxy.
