Explore the universe with members of the Royal Astronomical Society of Canada. Telescopes will be set up to provide amazing views of the Moon, the planets and more! Meet at the Chappell House Lawn.

This four-night course (April 5, 12, 19 & 26) is open to budding astronomers ages 12 and up! The course is taught by members of the Royal Astronomical Society of Canada – Mississauga Centre. If the sky is clear, there will be observing for 30 minutes at the end of each session. Please register before March 16, 2018. Note: A minimum of 15 participants are required to run the course.

Telescopes will be available to view the Moon, the planet Jupiter with its moons, the planet Venus, and various deep-sky wonders. A local astronomer with a sky pointer will be on hand to trace out constellations. Dress warmly! Please stay close to the walkway to protect the wildflower plantings. Anyone who can help out with a telescope or otherwise is warmly encouraged to do so. Especially if you are bringing equipment, a good place to park is on Charles Lane just west of where it meets Sumner lane.

This weekend tour introduces families to the wonders of astronomy through an indoor planetarium experience, craft activities for younger visitors and stargazing. Visitors will spend time in both the main building and observatory visiting the 1.88m (74") telescope, learning its history and getting to see celestial objects firsthand (weather permitting).

(with telescopes! weather permitting... and astronomically-themed music from the 17th and 18th centuries)

Everyone is invited to join us and Durham Skies on July 21 for stargazing at the edge of Lake Ontario. Take a free look through different kinds of telescopes (including solar-filtered scopes) to get close-up looks at sunspots, craters on the Moon, brilliant Venus, rosy Mars, giant Jupiter, and Saturn with its rings. Peer deep into space and try your hand at spotting faint star clusters and nebulae. You can even bring your own telescope along and we'll give you expert advice on how to use it better.

Join us in the gallery at 7:00pm for informal talks by artists about their work. Follow us outside to Lisgar Park across the street when it gets dark - where members of the RASC and York University will set up telescopes.
