Join award winning author and host of Discovery Science’s Meteorite Men Geoff Notkin for a special appearance at the ROM.

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.

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.

Cloudy or clear, join us for programs including presentations in our Skylab and space-themed arts & crafts (Space Crafts!) and tours of the big telescope. Evening observing - weather permitting through our telescopes on the lawn only.  No direct viewing through the big telescope tonight for crowd safety.

Kerry-Ann will be talking about her journey in the intense hobby of astrophotography from 2007 up to 2015 and sharing some of the stories behind the many objects that were captured along with her more recent projects and goals.

The Department of Physics invites faculty, students and the public to our 40th 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.

Speaker: Lauren Hetherington In 1572, astronomers around the world saw a brilliant supernova which outshone every other star in the sky. It faded from view over the following two years and yet, today, we can still detect light from this ancient stellar explosion. How can this be? The answer lies in light echoes: light reflected by dust far from the initial explosion. Join us for the May AstroTour talk to discover what can we learn from these radiant echoes in space and how it is that they often look like they’re moving faster than the speed of light.
