Comedians! Scientists! Celebrities! Musicians! Canada’s most celebrated astronaut hosts the world’s most impressive, funny, and talented people. Afghan heroes, British robotics experts, Hollywood actors, Australian corpse farmers or even a pair of Spanish cyborgs, you never know who’s going to show up. Now in its sixth sell-out year, it guarantees to be a wild return. It’s fun, it’s intelligent, it’s the best night in the city. You don’t want to miss it.

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? Then come on down to ASX's November Graduate Student Panel!

Join The Royal Astronomical Society of Canada's Tom Vassos for a tour of the universe highlighting several of the great astronomy discoveries made in the last 25 years. Explore life on the International Space Station and many fun facts about the universe. Drop-In Program. First Come, First Seated.

Speaker: Max King, University of Toronto In July 2015, the New Horizons spacecraft flew past Pluto, photographing the last unexplored major body in our solar system. Taking over 25 years from its original conception to its phenomenal photographic fly-by, New Horizons upended the space industry. We will explore the story behind the most unlikely expedition into our solar system, the development of the mission from scrap paper to the spacecraft itself.

After five years at the helm, Randy Attwood has announced that he will step down as the Executive Director of The Royal Astronomical Society of Canada. To celebrate Randy’s tenure, we are hosting an open house on October 26th.

Albert Einstein predicted a century ago the existence of gravitational waves – ripples in the fabric of spacetime moving at the speed of light. It was believed that these ripples were so faint that no experiment would ever be precise enough to detect them. But in September 2015, LIGO did exactly that. The teams working with the Laser Interferometer Gravitational-wave Observatory (LIGO) detectors in Louisiana and Washington measured a loud gravitational wave signal as it traveled through the Earth after a billion-year journey from the violent merger of two black holes.

Please remember to dress warmly because it will be cold tonight.

Raise your beakers! The Science Centre turned 50, and we’re inviting you to celebrate with us. Featuring the all-new MindWorks—an innovative Science Centre original exhibition exploring memory, creativity, emotions and the mind’s inner workings with virtual reality, a large scale obstacle course and a mega multiplayer decision-making competition.

Researchers from around the world work out of the Mars Desert Research Station in Utah and the Flashline Mars Arctic Research Station on Devon Island, Nunavut, to prepare for human exploration of Mars.

Our understanding of the motions of stars within our Milky Way and of the many small galaxies that orbit around it has changed dramatically over the past few years owing to new observational surveys and significant advancements in our understanding of galaxy structure.
