Pulsars, born after the splendid explosion of massive stars, are the most compact objects in the visible universe. Sitting on Earth, we receive regular pulses of light from pulsars. The accuracy of the period between pulses can sometimes rival that of an atomic clock. Pulsar studies have won two Nobel prizes: one for their discovery, and one for the first indirect evidence of gravitational waves. In this talk, Dongzi Li will explain how the compact nature and the excellent periodicity of pulses help make previously difficult studies feasible.

Join us at the Ontario Science Centre for our monthly Solar Observing on the TELUSCAPE observing pad. This is the area in front of the Science Centre's entrance. We use specialized telescopes that are safe to aim at the Sun. Check our home page on the Friday prior for go/no-go calls as this event is weather dependent.
