Revolutionary progress has been achieved in the science of cosmology over the past 30 years. Powerful experiments, made possible by new technologies, have transformed our understanding of the universe. We have unveiled the laws of physics that govern time and space on the grandest scales, from the big bang to present day.

David Paige is Professor of Planetary Sciences at UCLA. He is a Principal Investigator on NASA’s Lunar Reconnaissance Orbiter mission, and also on NASA's MESSENGER spacecraft, which discovered ice on the Moon and on Mercury.

Join McMaster's Sidewalk Astronomy in observing the total lunar eclipse, the last of the lunar tetrad! As part of Science Literacy Week 2015, they are organizing a free public observing event for everyone. Remember to dress warmly, it's going to be a cold night! Observing is subject to the weather. Please check the website for announcements prior to the event.

To celebrate National Science Literacy Week, University of Toronto Science & Engineering Engagement is showing the 1997 Space Exploration film: Contact followed by a Question & Answer session with: Keith Vanderlinde, Assistant Professor, Dunlap Institute and Department of Astronomy and Astrophysics Laura Newburgh, Postdoctoral Fellow, Dunlap Institute for Astronomy and Astrophysics

Neil Turok, Director, Perimeter Institute

Prof. Keith Vanderlinde has spent the last decade building and using telescopes to study the Universe: its composition, history, and eventual fate. Aided by technologies that make cell phones possible, and which make video games a staple of modern culture, he and colleagues from across Canada are building a massive new radio telescope in Penticton, B.C., which will map a larger volume of space than ever attempted before. Lecture: 8:10 - 9:00 PMTelescope observing: 9:00 - 11:00 PM

Speaker: Nick Tacik Black holes are one of the most fascinating objects in the universe. From science fiction to the offices of astrophysicists, their mystery has captivated many. But what do we really know about them? Surprisingly, a whole lot! What happens when you fall into a black hole? What happens when two black holes collide? How do we know black holes really exist? What is a wormhole? Is spaghettification even a real word? In this talk, Nick Tacik will answer all these questions, and more, about the wondrous world of black holes.

Aided by the technologies that make cell phones possible and video games a staple of modern culture, he and colleagues from across Canada are building a massive new radio telescope which will begin mapping a larger volume of space than ever attempted before to study the mysterious Dark Energy which drives the universe's evolution.

Paul Delaney, York University The search for Pluto started in 1781 with the confirmed observation of Uranus. It took until 1930 for an astronomer to find the "9th planet." Little did Clyde Tombaugh know the excitement his discovery would generate in the 21st century. However, the secrets of the last of the "classical planets" would not be revealed until the flyby of the New Horizons spacecraft in July 2015. This lecture will summarize the history of Pluto and the results sent back to date from New Horizons. The revelations are unexpected!
