Our guest speaker for this meeting will be Alanna Mitchell. Alanna is the author of The Spinning Magnet, her most recent book, all about the Earth’s magnetic field. Part history, part science, it explores all we know about one of the most important and least understood parts of our planet. From our discoveries about the connection between magnetism and electricity to the possibility that we are about to undergo a pole reversal, Alanna brings a spirited talk about this fascinating subject off the page onto our stage.

We are a go for Friday. Please remember to dress warmly. Note also that the sky may be cloudy to start with but should clear around 9:00pm.

Hover above the Moon like an astronaut and get eye-to-eye with the planets. Find colourful stars, star clusters, bright nebulae and even another galaxy. Our monthly City Star Party is the place to catch universe from within the city limits at Bayview Village Park. If you don't have a telescope then you will find many astronomers who would love to share a view. If you are thinking of buying a telescope, viewing with other people's equipment is the best way to make a good choice. If you have a telescope or binoculars, please bring it!

Join us at the Ontario Science Centre this week for 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. We will be set up from Monday to Saturday from 10:00am-12:00pm daily. Check our home page for go/no-go calls as this event is weather dependent.

This year’s Spring Work Party will be held on the weekend of May 4-5, 2019. Volunteers are invited to arrive as early as Friday late afternoon to enjoy some social time before the work begins the next morning and comes to an end around noon on Sunday. As a volunteer, you will be provided all meals from Saturday breakfast to Sunday lunch plus all regular CAO user fees are waived for the weekend. Tasks at this event will include the usual spring clean up chores plus various upgrades and repairs to the house and observatories.

Showtimes: 7:00pm, 8:10pm, 9:15pm

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.
