Science is like puzzle-solving. Making sense of quantum theory is a particularly thorny kind of brain-twister, with more than its fair share of mysteries. If you are stuck on a puzzle, it may be because you have made a false assumption about the nature of some entity that is absolutely central to the whole business. If so, you have made a category mistake: you are not just wrong about what this entity is, but about what sort of thing it is.

We owe our existence to the sun and stars. The atoms in our body are created by stars. The sun's energy makes life possible. When the sun and stars "burn out," they produce bizarre remnants called white dwarfs, neutron stars, and black holes. In this profusely illustrated, non-technical presentation, you will learn about some of the strangest, most extreme objects in the universe.

As part of the UTM Lecture Me! series, Prof. John Percy provides a profusely-illustrated, non-technical, light-hearted talk that gently corrects a variety of “heavenly errors,” from basic concepts to the birth of the universe. Lots of time for Q&A!

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

Showtime: 3:00pm 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!

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

Showtimes: 7:00pm, 8:10pm, 9:15pm

This is the 15th Annual Symposium organized by ASX and this year's theme is: "Into the Unknown: The Future of Space Exploration"

Dr. Laura Parker will give an overview of the techniques used to map the universe on the largest scales, which have enabled us to measure dark energy and dark matter.

Magnetars are some of the most extreme objects in the known universe. Though small in size, they possess the strongest magnetic fields in the universe and are the densest objects known. In this talk, we’ll go over the incredible behaviour seen in these rare objects — from tiny explosions to outshining the rest of the X-ray sky combined.

With Alanna Mitchell, acclaimed science journalist, author and contributor to CBC Radio’s Quirks & Quarks.
