Everyone is invited to join us and Durham Skies on April 20 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, Venus, and the springtime constellations. 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.

Celebrate International Astronomy Day at the Ontario Science Centre!

Every year the Faculty of Science at York University joins forces with Main Street Markham to present Science Rendezvous at the award-winning Markham Farmers’ Market.

Science Rendezvous is a free annual all-day festival that brings science out of the lab and onto the street with the ultimate goal of improving student enrolment as well as public involvement in the science, technology, engineering, and mathematics (S.T.E.M.) fields.

Join us for Science Rendezvous on Saturday, May 12, 2018, in the heart of Ryerson Campus! Science Rendezvous is Canada’s annual celebration of science. This free festival, targeted to all age groups, makes science accessible to thousands of people with a day of engaging, informative and interactive events. Science enthusiasts across the country take their passions to the people to encourage a public understanding of the great impact science and technology have on our lives and our changing world.

How were the ancient Egyptian day and night divided? What do we know about keeping time during the span of pharaonic history? Have many objects used for timekeeping survived? Do we know who made and used them and why? This talk discusses ‘formal’ methods for measurement of hours in ancient Egypt, giving an overview of the surviving evidence including sundials and water clocks. We will compare different instruments and trace the extent to which we understand the time-keeping function of each.

What is the sound of a twinkling star? Can planets keep a beat? How loud was the big bang?

Showtime: 3:00pm Often, when we think of the Solar System, we think of the planets and the Sun and nothing more. But what about all the other stuff? There are millions of asteroids in the asteroid belt, tens of millions of objects in the Kuiper belt, and probably trillions of objects in the Oort cloud—not to mention the hundreds of moons and dozens of dwarf planets that are members of the Sun’s extended family.

Showtimes: 7:00pm, 8:10pm, 9:15pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!
