This Fall and Winter, spend a Sunday afternoon in the OTHER dome at the DDO!

Have you ever looked through a telescope? Take a tour of the night sky through a telescope and snap a photo or two of your favourite celestial body.

Join us at the Ontario Science Centre for our monthly 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.

Magnetism is one of the fundamental forces of nature and shows up in many places in our daily lives, but it’s not something that most people associate with astronomy.

RCIScience is delighted to recognize Canadian journalist, author and broadcaster, Dan Falk, with the 2019 Fleming Medal for Excellence in Science Communication.

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.

Want to know more about how modern astronomy is conducted? Bursting with questions on how exoplanets are detected or how galaxies are surveyed? Not sure what to ask, but just want to learn more?

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.

Black holes are perhaps the strangest thing in a very strange universe.
