Showtimes: 7:00pm, 8:00pm, and 9:00pm For thousands of years, humans have studied the heavens from the confines of the Earth.  In the last century, however, we have begun sending both people and machines to other worlds. Where have we gone, and what discoveries have we made? This planetarium show will delve into the history of space exploration, from the first tentative steps made during the Space Race to the first-ever flyby of Pluto by the New Horizons spacecraft.

The Riverwood Conservancy and the City of Mississauga are pleased to present “Our Night Sky”, a new show for young audiences of all ages, created and performed by the Chamber Music Society of Mississauga (CMSM). This free admission, Preview Performance, is scheduled for Monday, August 31, rain or shine, beginning at 8 pm in the Riverwood Barn. Bring your own lawn chairs.

What we can see in the universe represents only the tip of the iceberg of what's out there. Dr. Sean Tulin (York University, Department of Physics & Astronomy) discusses the physics of the dark side: dark matter, dark energy, and—perhaps—dark forces that guide the past, present and future of our universe. The Science of Science Fiction series is presented in collaboration with York University's Faculty of Science.

Built up your thirst for more astronomy!? Great! Because on Thursday, August 20th, astronomers from the University of Toronto will be back at the Tranzac Club for another fun evening of pints, mind-expanding talks, games and prizes. Plus, following all the talks and games, there'll be plenty of time and plenty of astronomers around to answer all your cosmic questions.

Speaker: Jamil Shariff

The Astronomy Club at York University and the York University Observatory present Toronto's very own Plutopalooza event, an event that is being held in cities across the world! Plutopalooza is a celebration of New Horizons' arrival at the Pluto system after its nine-year journey across the solar system. It will bring together astronomy and space exploration enthusiasts to share together their excitement for the spacecraft's arrival at this distant world.

Dr. Wendy Taylor (York University Physics & Astronomy) talks about the science of antimatter. What is it? How is it made, trapped, studied and used. And what can it tell us about how the universe works? The Science of Science Fiction series is presented in collaboration with York University's Faculty of Science.

There are moments in history when the right people converge at the right place, in the right time, to catalyze something entirely new. Convergence will be one of those moments. Physics is at a turning point. The most sophisticated experiments ever devised are decoding our universe with unprecedented clarity -- from the quantum to the cosmos -- and revealing a stunning simplicity that theory has yet to explain.

Everyone is invited to join the DRAA for a fun evening of stargazing at Millennium Square in Pickering. You will enjoy spectacular views of the Moon, Saturn, deep space star clusters and galaxies through big telescopes. The DRAA will have an information booth filled with astronomy literature and hand outs. Do you have a telescope but are not sure how to use it? Bring it along and DRAA members will be happy to help you!
