Roberto Abraham, University of Toronto Bigger telescopes are usually better telescopes…but not always.

Kerry-Ann will be talking about her journey in the intense hobby of astrophotography from 2007 up to 2015 and sharing some of the stories behind the many objects that were captured along with her more recent projects and goals.

It's time for another Astronomy on Tap T.O.! On Thursday, May 21st, 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.

Showtimes: 7:00pm, 8:00pm, and 9:00pm There are many misconceptions about our universe, and the most common one is also the simplest – its size. Our universe is much bigger than we imagine it to be, and only through visual aid (such as a planetarium) can one really grasp the true dimensions of it. This planetarium show will journey through the different scales of the universe, starting with familiar objects like the moon and the Earth, and ending with the furthest reaches of the observable universe.

Showtimes: 7:00pm, 8:00pm, and 9:00pm The Universe is wondrous, with untold treasures to satisfy desires both large and small, but it is not for the timid. It is a wild place with devastating asteroids, deadly black holes, colliding galaxies, and exploding stars. Join us as we explore some of these magnificent and menacing phenomena. Your show will be approximately 50 minutes long. All of our shows are presented live and in person by University of Toronto astronomers. Plenty of time is allocated for questions from the audience.
