A Fast-Moving Pulsar Fractures the Milky Way's Galactic Bone

The center of the Milky Way is a busy place, tightly packed with stars and dominated by the supermassive black hole Sagittarius A*. It also features powerful magnetic fields that regulate star production, influence gas dynamics and gas cloud formation, and even affect the accretion processes around Sagittarius A*. Gigantic filaments of gas that look like bones form along the magnetic field lines, and one of them appears to be fractured.
