More than 99 percent of the visible matter in the universe is built from protons and neutrons and the nuclei that they form. This rich structure emerges dynamically from the complex interactions of quarks and gluons, the most elementary particles that have been discovered. Understanding how nuclear physics arises from the underlying quark and gluon dynamics is a computational challenge that pushes the capabilities of the world’s largest supercomputers.

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. We observe from the Long Sault Conservation area, an hour outside of Toronto. We meet around dusk once a month in the parking lot for views only seen in dark sky conditions. We hold this event on the first clear night of our week-long window, so the date and time are determined closer to.

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.

For the first time ever, Ryerson University will be hosting the world-renowned astronaut, Chris Hadfield! “Beyond the Horizon: The Hadfield Experience” aims to inspire, motivate and guide you to becoming changemakers of society.

In this talk and slide show, Michael Watson will discuss his recent month-long trip to Australia, which included several nights of stargazing and astrophotography from the dark skies of the Australian Outback. He will talk about how he prepared for the trip, the equipment that he took, and how he produced the photos that you will see. His astrophotos will be interspersed with photos of some of the sights from around the Land Down Under.

Cosmic rays are the most energetic particles in the universe. Travelling at speeds mere fractions off from the speed of light, they accelerated in the remnants of dying stars and supermassive black holes. In this talk, we’ll talk about how cosmic rays interact with and influence their surroundings as the move throughout galaxies and intergalactic space along magnetic field lines.

Welcome back Dr. Dave Williams to talk about Defying Limits: Lessons from the Edge of the Universe — an inspirational, uplifting, and life-affirming memoir about passion, resilience and living to the fullest. From spacewalking records to living under the sea to performing surgery in zero gravity, learn how a curious kid from Saskatchewan rocketed out of this world. Dr. Dave will be available for book signing after the conversation. Presented in collaboration with Simon & Schuster Canada.

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).

Come use your hands and brains to learn about and explore through NASA's Space Apps Toronto Youth Program. As the official youth branch of the Toronto NASA Space Apps Challenge, youth ages 7–13 will explore and learn about space like never before.

Observational astronomers use telescopes that look at the furthest distances in the Universe to look back in time and trace the growth of structure in the cosmos. Recent multi-wavelength measurements have helped us to constrain the components that make up the Universe and how those components evolve. We now know that most of the Universe is made up of dark matter and dark energy, but the nature of these components remains largely unknown. In this talk Dr.
