Wow! Gorgeous image of the Magnetic Lines of Force of Spiral Galaxy M77!!! More to follow Maj William W. 'Bill' Price!!!

I could not find a video with M77 showing the Magnetic Lines of Force as shown in your APOD composite image... However, I did find a fundamental illustration of MLF as shown in a laboratory... This is a simple illustration, but one can extrapolate this to the likes of Spiral Galaxy M77... I also found a great video on M77, which I will post separately from you and I, which I believe your followers will find most interesting... Here is the link to the lab example! https://youtu.be/8llkHQtaOlg

Thank you, my friend Maj William W. 'Bill' Price for posting the NASA Astronomy Picture of the Day (APOD) for December 16, 2019 entitled "The Magnetic Fields of Spiral Galaxy M77."

"Explanation: Can magnetic fields help tell us how spiral galaxies form and evolve? To find out, the HAWC+ instrument on NASA's airborne (747) SOFIA observatory observed nearby spiral galaxy M77. HAWC+ maps magnetism by observing polarized infrared light emitted by elongated dust grains rotating in alignment with the local magnetic field. The HAWC+ image shows that magnetic fields do appear to trace the spiral arms in the inner regions of M77, arms that likely highlight density waves in the inflowing gas, dust and stars caused by the gravity of the galaxy's oval shape. The featured picture superposes the HAWC+ image over diffuse X-ray emission mapped by NASA's NuSTAR satellite and visible light images taken by Hubble and the SDSS. M77 is located about 47 million light years away toward the constellation of the Sea Monster (Cetus)."

Thank you, my friends Maj Marty Hogan and Sgt (Join to see) for mentioning me.

This wonderful image brought to mind a classic Beatles song
