Join us this week if skies are clear!

See the milky way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light polution, there is so much to see. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

Video of the talks Join us for our monthly recreational astronomy night meeting. This is where our members get to show their latest projects, or give tutorials and tips on just about everything to do with Astronomy. Talks start at 7:30, socializing starts at 7:00.

Solar System Social is a speaker series about planetary science which is geared to the general public. This event features Jordan Bimm (former NASA fellow in the History of Space Science) and David Hamilton (former NSERC fellow in Technologies and Techniques for Earth and Space Exploration). Respectively, their talks are titled " Putting Mars in a Jar: The Military Origin of Astrobiology" and "What can we learn from lasers on Mars?" Doors at 6:00pm, Show at 6:30pm

On the weekend of April 28-30, 2017, developers, makers, engineers and entrepreneurs will take on NASA-designed challenges, creating solutions that range from silly to serious, fantastical to feasible. Build a team, pick a challenge, and leverage your access to an extraordinary roster of mentors featuring past and present astronauts, aerospace engineers, and designers.

Join us as we celebrate International Astronomy Day with a fun-filled day – and night – of exciting programs and experiences for visitors of all ages.

Observe the stars via telescope with members of the Royal Astronomical Society of Canada. Witness the crescent Moon and Jupiter along with lively activities and demonstrations in this universally enlightening – and free – evening. In the event of inclement weather, Evening Star Party activities will proceed indoors in the Telus Conference Room.

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!

More than a billion years ago, two black holes collided. In the final second of their long life together, the black holes banged out a rhythm like mallets on a drum, creating gravitational waves – ripples in the shape of spacetime. One hundred years ago, Albert Einstein predicted the existence of such waves, though it seemed improbable – if not outright impossible – that we’d ever be able to actually detect them. They were long considered too faint for any earthbound experiment to measure.

The Department of Physics invites faculty, students and the public to its 42nd annual celebration of physics. The Welsh Lectures in Physics have been held annually since 1975 in honour of H.L. Welsh, a distinguished former faculty member in the Physics Department. They are the major public event in the life of the Department of Physics and are intended to celebrate discoveries in physics and their wider impact. They are intended to be broadly accessible to an audience drawn from across the university, other academic institutions and the interested public.
