    Using the National Science Foundation’s Karl G. Jansky Very Large Array radio telescope, a team of astronomers has captured for the first time an image of large-scale, coherent, magnetic fields in the halo of a faraway spiral galaxy, confirming theoretical modeling of how galaxies generate magnetic fields and potentially increasing knowledge of how galaxies form and evolve.

    The international consortium, led by scientists from the Max Planck Institute for Radio Astronomy in Bonn, Germany, and...
