How far does the magnetic field extend to and beyond the spiral galaxy? For decades, astronomers only knew that certain spiral galaxies had magnetic fields. However, after the NRAO’s Very Large Array radio telescope was upgraded in 2011, it was discovered that these fields could extend vertically from the disk for thousands of light-years. The image of a spiral galaxy at the edge of NGC 5775 recorded in the CHANG-ES study also reveals possible stray magnetic field lines in the spiral image. Electronic radiation follows the lines of the Milky Way’s magnetic field and revolves around those lines at almost the speed of light. The fibers in this image are made from these traces in VLA data. Visible light images were made based on data from the Hubble Space Telescope. In the photo you can see the pink gaseous regions where the stars are born. NGC 5775
