To map the galaxy’s magnetic field lines, Dr. Chuss and his colleagues flew at 45,000 feet aboard the Stratospheric Observatory for Infrared Astronomy, or SOFIA, a 747 outfitted for astronomy.

Unlike the geographic North Pole, which marks a fixed location, the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion.

The group’s calculations showed that magnetic fields can be generated about 20,000 miles (32,100 kilometers) below the sun’s surface — far closer to the surface than had previously been assumed.
