Three Mysterious Pulsar Glitches Reveal What’s Happening Inside a Neutron Star

Astronomers have discovered three sudden rotation changes, or glitches, in the young neutron star PSR J1637−4642.

After more than a decade of apparent stability, observations from the Murriyang radio telescope revealed these unexpected speed-ups, offering new clues about superfluid matter hidden inside neutron stars. The star’s gradual recovery could help scientists understand how matter behaves under the most extreme conditions in the universe.
