The Milky Way Has a Mysterious ‘Broken Bone’


Galactic bones, filaments of radio-wave-emitting particles, run through our galaxy, and one of them has a fracture. New analysis suggests collision with a neutron star may have caused it.

The research team involved found signs of a pulsar, a neutron star spinning at high speed, in the same region as the broken bone. Pulsars are alternative versions of a neutron star where, in addition to being compact objects, they rotate at high velocities and produce strong magnetic fields. At the moment there is no instrument that can see them directly due to their size and distance, but radio telescopes can detect the electromagnetic waves they emit and hear them by converting these into sound.
