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.


Jim has a degree in Mathematics, an Honours degree in Computer Science, a Masters in Astrophysics, and is finalising his Ph.D., also in Astrophysics. Jim has recently spoken at NASA’s Jet Propulsion Laboratory, The Royal Society, and just been published in Nature on his research into Vela pulsar. He also appears regularly on ABC radio to discuss all things science and astronomy. He is passionate about science communication and teaching mathematics, especially when it comes to inspiring future generations.
