Astronomers peer back into the past with the world's largest telescopes. They see billions of galaxies, and they find indications of evolution and youth. Before the first galaxies, there were the Dark Ages. And before then, the Big Bang. But there is much of the universe that astronomers cannot probe. Prof Silk will describe the universe that we see, and speculate about the universe we cannot see.

On April 11–13th, developers, makers, engineers and entrepreneurs will take on 25 NASA-designed challenges, creating solutions that range from silly to serious, and fantastical to feasible. Build a team, pick a challenge, and leverage your access to extraordinary mentors roster featuring past and present astronauts, aerospace engineers, and designers.

Mars is closest to earth for the year, giving the best views in a telescope.

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 for our monthly Solar Observing on the TelusScape 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. Check our home page on the Friday prior for go/no-go calls as this event is weather dependent.

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