Based on data from NASA's Stratospheric Observatory For Infrared Astronomy (SOFIA), Villanova University researchers developed a map of the magnetic fields in the Milky Way. For Strange Maps, Frank Jacobs: The colors show the interaction between warmer dust clouds (pink), cooler ones (blue), and magnetic fields, indicated by radio filaments (yellow) — mysterious tendrils up to 150 light-years long. By revealing variations in the orientation of magnetic fields across dust clouds (some with fanciful names like The Brick and Three Little Pigs), this map offers a first glimpse at the complex arrangements of dust and magnetism in the CMZ.
