Making use of the National Science Foundation’s Karl G. Jansky Really Big Array radio telescope, a staff of astronomers has captured for the initially time an graphic of big-scale, coherent, magnetic fields in the halo of a faraway spiral galaxy, confirming theoretical modeling of how galaxies deliver magnetic fields and likely growing knowledge of how galaxies kind and evolve.

The intercontinental consortium, led by scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and which includes astronomers from the NSF-funded National Radio Astronomy Observatory in Charlottesville, Virginia, described the results in the journalAstronomy & Astrophysics.

“To recognize how stars like the sunshine and planets like Earth came to be, we ought to comprehend how galaxies, such as our Milky Way, type and evolve,” reported Matthew Benacquista, a project director in NSF’s division of Astronomical Sciences. “This challenge is an endeavor to measure galactic magnetic fields and find out how they impact the way that interstellar gases are ejected from galaxy disks and contribute to galaxy formation and evolution.”

The spiral galaxy, determined as NGC 4631 or the “Whale Galaxy,” is noticed edge-on in the image, with its disk of stars revealed in pink. The field lines are proven in environmentally friendly and blue, extending over and above the disk into the galaxy’s extended halo. Green suggests filaments with their magnetic field pointing roughly towards the viewer, and blue indicates filaments with their magnetic fields pointing away. This phenomenon, with the discipline alternating in route, has hardly ever been seen prior to in the halo of a galaxy.
