Introduction to RASC and Astronomy, overview of the course, astronomy history and "Canada in Space." For more details: http://www.rascto.ca/content/nova-astronomy-course-

Dark matter is puzzling. We can't see or touch it, but we believe it makes up about 85% of the matter in the Universe. Canadian astronomers are at the forefront of the search for the true nature of this elusive substance. Join us on Monday, October 23rd for an evening of fascinating talks in celebration of Dark Matter Day. From the first evidence for dark matter in distant galaxies to cutting-edge tools for detecting dark matter right here on Earth, this is your chance to find out what dark matter is, why it matters, and how we'll find it.

Join the Yukon Centre with special guest Dr. Phil Plait from 10:00pm–midnight (EDT). Come discover the mysteries of our northern skies and what can be seen when the northern lights can’t. Impress your guests with interpretation of the northern lights and wow them with your knowledge of what lies beyond.

Showtimes: 1:00pm and 2:30pm

Join the Hamilton Amateur Astronomers between 7:00 and 11:00pm on Saturday, October 21, 2017 at the Niagara Gateway Tourism Centre located just off Casablanca in Grimsby. Enjoy views of the crescent moon and perhaps the planets Saturn, Uranus and Neptune. Andromeda Galaxy? Maybe. Come out and view through a telescope and see for yourself!!

Showtimes: 11:00am and 12:30pm

Join us at the Ontario Science Centre for our monthly Solar Observing on the TELUSCAPE 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.

The Orionid meteor shower, usually shortened to the Orionids, is the most prolific meteor shower associated with Halley's Comet. The Orionids are so-called because the point they appear to come from, called the radiant, lies in the constellation Orion, but they can be seen over a large area of the sky. Orionids are an annual meteor shower which last approximately one week in late October. In some years, meteors may occur at rates of 50–70 per hour - Wikipedia

Showtimes: 7:00pm, 8:00pm, and 9:00pm The stars in the night sky seem unchanging and eternal, and have remained the same for the history of human civilization. However, over millions and billions of years, new stars are born, live out their long lives, and eventually die in a blaze of glory. In this show, we will be exploring the lives of stars by visiting stellar nurseries, supernova remnants and much more!

The moon is between us and the sun. Without the moon in the sky at night, deep sky objects are easier to observe.

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 our own galaxy, The Milky Way, and its friends to better understand the social habits of disk galaxies and how they spin. Chronicles of a Peculiar Universe is a series of talks presented in collaboration with York University's Faculty of Science.

See the Milky Way and galaxies with the unaided eye. Point your telescope to find the many dim deep space objects that sprinkle the sky. Away from Toronto's light pollution, there is so much to see. We usually observe from Long Sault Conservation Area, but this month we will be going to Glen Major Forest. Observing will begin around dusk in the parking lot. We will hold this event on the first clear night of our week-long window, so the exact date will be determined closer to the event.
