Map of magnetic fields in the Milky Way
Briefly

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.
