In this series of talks presented by the Faculty of Science in collaboration with the Toronto Public Library, we take you on a dazzling cosmic journey to explore some of the most fascinating corners of our universe.
Quasar, Quasar, Burning Bright
October 11, 2017 at 6:30-7:30 pm, Danforth/Coxwell Branch
Quasars are the brightest objects in our Universe and are formed when matter spirals into supermassive black holes. They contain rotating disks as big as our solar system and hotter than the Sun. Professor Patrick Hall discusses these fascinating objects and how they tap the strong gravity of black holes.
How to Get to Mars
October 12, 2017 at 6:30-7:30 pm, Lillian H. Smith Branch
For decades NASA has been sending orbiters, landers and rovers to Mars for research and exploration, and the agency is aiming to send humans to the Red Planet in the 2030s. Professor Robin Metcalfe provides an overview of our past, present and future missions to Mars.
The Social Habits of Galaxies
October 17, 2017 at 7:00-8:00 pm, S. Walter Stewart Branch
November 16, 2017 at 7:00-8:00 pm, Don Mills Branch
Most galaxies enjoy the company of other galaxies and organize into various shapes known as the “cosmic web.” Many of them also like to spin – creating beautiful, disks of stars and gas. PhD student George Conidis examines copies our own galaxy, The Milky Way, and its friends to better understand the social habits of disk galaxies and how they spin.
The Secrets of Our Dark Universe
November 11, 2017 at 2:00-3:00 pm, Brentwood Branch
Most of our Universe is made up of dark matter and dark energy, but so far scientists have had a hard time detecting or explaining them. PhD student Alexandra Terrana explores some of the big open questions in cosmology, what dark matter and energy are, and how an alternative theory of gravity might solve these mysteries.
Is Anyone Home?
November 14 at 6:30-7:30 pm, Barbara Frum Branch
Since 1995 thousands of planets have been detected orbiting other stars. Many of these worlds could possibly contain liquid water and even life. Professor Paul Delaney describes our current understanding of exoplanets, the ongoing search for them and the implications for the search for life.
