The earth's axis is perpendicular to its orbit with the North pole tipping away form the sun. In other words, the season is changing to Fall.

Professor Keith Vanderlinde has spent the last decade building and using telescopes to study the universe: its composition, history, and eventual fate. Aided by the technologies that make cell phones possible and video games a staple of modern culture, he and colleagues from across Canada are building a massive new radio telescope which will begin mapping a larger volume of space than ever attempted before to study the mysterious Dark Energy which drives the universe's evolution.

Juris Steprāns looks at logic in science fiction, including both the misconceptions and insights which scifi has produced about Gödel's theorem, one of the most misunderstood results of mathematics.

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 if skies are clear this coming Saturday morning.

From the earliest days of the first hominids and through the epochs into the 21st century, mankind has held a deep fascination with the night sky. In today’s technological society, massive mountaintop observatories and high-tech space telescopes are at the forefront of astronomical research, but an ever-growing group of individuals continue to peer up from dark fields, secluded parks and their own backyards in the quest to explore and understand the universe.

Showtimes: 7:00pm, 8:00pm, and 9:00pm How big is the universe? How can we seek to answer this question or understand the answer once we have it? Our universe is much bigger than we imagine it to be but, using analogies and visualizations, we can start to grasp its true dimensions. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.

Join us and Durham Skies this September for free stargazing down by the edge of Lake Ontario. Before sunset, come and have a safe look at our nearest star through special solar-filtered telescopes, and then as the sky gets darker, get close-up looks at craters on the Moon and the captivating rings of Saturn.

What star is that? How can I spot Orion’s Belt? How many planets can I see without a telescope? Learn your way around the night sky. The Riverwood Conservancy, The Earthshine Astronomy and Space Science Organization and the Mississauga Centre of the Royal Astronomical Society of Canada are teaming up to offer a 4-week course on astronomy. Upon completion the student will be able to identify the brighter stars and constellations.

There are astronauts and then there are space walkers. Only three Canadians have donned space suits and stepped into the void 400 km above the Earth to perform zero-G construction work on the International Space Station.

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.
