Pulsars are neutron stars that are the remnants of supernova explosions. They are highly dense and rotate rapidly, some with accuracy better than atomic clocks. The Vela pulsar famously “glitches” or speeds up in rotation roughly every three years. No glitch has ever been observed in-action with a radio telescope large enough to see individual pulses, until now. Some remarkable events occurred and these will be covered in detail. The presentation will be aimed at people who have a general interest in astronomy.
