Magnetic fields in the spiral galaxy Messier 77, also known as M77 and NGC 1086, are shown as streamlines over a visible light and X-ray composite image of the galaxy from the NASA/ESA Hubble Space Telescope, NASA’s Nuclear Spectroscopic Telescope Array (NuSTAR), and the Sloan Digital Sky Survey. The magnetic fields align along the entire length of the massive spiral arms of Messier 77, implying that the gravitational forces that created the galaxy’s shape are also compressing the its magnetic field. This supports the leading theory of how the spiral arms are forced into their iconic shape known as ‘density wave theory.’ SOFIA studied the galaxy using far-infrared light (89 microns) to reveal facets of its magnetic fields that previous observations using visible and radio telescopes could not detect.

NGC 3175 can be seen slicing across the frame in this Hubble image, with its mix of bright patches of glowing gas, dark lanes of dust, bright core, and whirling, pinwheeling arms coming together to paint a beautiful celestial scene. This image is made up of observations from Hubble’s Wide Field Camera 3 (WFC3) in the infrared and optical parts of the spectrum. Two filters were used to sample various wavelengths. The color results from assigning different hues to each monochromatic image associated with an individual filter. Image credit: NASA / ESA / Hubble / D. Rosario et al.

NGC 4631 is seen edge-on, with its disk of stars shown in pink; the filaments, shown in green and blue, extend beyond the disk into the galaxy’s extended halo; green indicates filaments with their magnetic field pointing roughly toward us and blue with the field pointing away; this phenomenon, with the field alternating in direction, has never before been seen in the halo of a galaxy. This VLA image shows a companion galaxy -- a small elliptical galaxy called NGC 4627 -- just above NGC 4631.
