'Quiet' pulsar suddenly reveals three glitches in 15 years of observations

PSR J1637−4642, a young neutron star spinning with metronomic precision, suddenly stuttered—three times across 15 years of Parkes radio telescope observations—revealing rotational glitches that jolted its cosmic clock, with one jolt altering its spin rate by nearly 3 parts per million. Astronomers are now left wondering: was this a one-time
