Pulsars are neutron stars which 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… A Tasmanian first! Some remarkable events occurred and these will be covered in detail.

Jim Palfreyman has a degree in Mathematics, an Honours degree in Computer Science, a Masters in Astrophysics, and has submitted his Ph.D. thesis in Astrophysics. He has spoken at NASA’s Jet Propulsion Laboratory on his research into the Vela pulsar and regularly appears on ABC Radio to discuss all things science and astronomy. Jim is passionate about science communication and teaching mathematics, especially when it comes to inspiring future generations.

The presentation is intended for people who have a general interest in astronomy.

Admission: $6 General Public, $4 Students, Friends of the Museum and members of Launceston Historical Society
