Join us at the Ontario Science Centre for our monthly Solar Observing on the TelusScape observing pad. This is the area in front of the Science Centre's entrance. We use specialized telescopes that are safe to aim at the Sun. Check our home page on the Friday prior for go/no-go calls as this event is weather dependent.

Speaker: Ari Silburt The Moon is intimately connected to humans, whether we realize it or not. It has been there since the formation of the Earth, and has watched over life as we evolved to the present day. Like ourselves, the Moon has also been changing with time, and there are many layers to its existence. In this lecture I will re-acquaint the public with the Moon, describing its formation history, its relationship to humans, its current relationship with the Earth, and future space plans on the Moon.

Eric Poisson, BSc, MSc, Ph.D, Department of Physics, University of Guelph General relativity, Einstein’s greatest scientific achievement is turning 100 this year. The speaker will describe how a companion body can raise a tide on a black hole, much as the Moon raises a tide on Earth and what consequences this can have on the motion of the two-body system.

Family Nights are a great introduction to the night sky for our younger guests. Look through telescopes, make some space crafts, visit the Skylab and find out what's really up there! Family Nights require tickets to be purchased in advance. This program runs regardless of sky or weather conditions. If skies are clear you can check out the night sky through a variety of telescopes including the biggest optical telescope in Canada! The evening also includes a presentation in our special Skylab that offers great (virtual) night sky viewing.

Showtimes: 12:30pm and 2:00pm **Please note that this show will geared towards children and costumes are encouraged!**

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!
