This image shows the huge extent of a spiral galaxy’s magnetic field. See https://public.nrao.edu/news/image-galaxy-magnetic-field/ for image and more information.
Nov. 26, 2019. The magnetic fields in the halo of NGC 4631 show magnetic fields that reverse direction in a regular fashion. A magnetic dynamo could explain this behaviour, never before seen in a galaxy’s halo. See https://public.nrao.edu/news/giant-magnetic-ropes/ for image and more information.

Astronomers studying gas halos around nearby galaxies were surprised when detailed studies with the National Science Foundation’s Karl G. Jansky Very Large Array (VLA) showed that one of their subjects is not a single galaxy, but rather two, nearly perfectly superimposed on the sky to masquerade as one. The discovery allowed them to use the alignment to learn otherwise-unobtainable facts about the nearer galaxy. Image and info at
