- Gary Welch (SMU Astronomy Professor Emeritus) - Gravity's Way: Shredding Galaxies on a Laptop
This talk will show what can happen when a retired astronomy prof decides to scratch a long-festering itch. Milestones along his search for relief will blaze across the screen, including Python animations of star clusters tiny and large, and of galaxies both isolated and crashing. Projects for the future - dreams and just plain madness - might be mentioned if time allows.
- Patrick Kelly (Halifax Centre) - The Sun is not an Average Star. The Earth is not an average planet.
Stars and their planets form at the same time, from large clouds of gas and dust. The vast majority of stars are smaller, cooler, and less luminous than the Sun. Over 5000 exoplanets have been found so far; very few have properties similar to those of the Earth. Most people agree you need a carbon-based chemistry acting in liquid water for life to begin. Therefore, life on other planets (if it exists!) is expected to be found in the Goldilocks Zone around their stars, the distance at which a planet can have liquid water at its surface. This criterion alone rules out a lot of planets from having “life as we know it”. As it turns out, there are places in our own solar system with a lot more liquid water than Earth, so life may be a lot closer than we think!

Members may be found observing at the St. Croix Observatory on almost every clear, dark night. Once a month, we encourage members and their guests to congregate at SCO, at which time new members are particularly welcome.
Members are advised to sign up to the email discussion list to keep up to date on gatherings of fellow observers.

For over 30 years, the RASC Halifax Centre and other local groups have hosted the Nova East Star Party. It was originally established as the camping and observing weekend for the Halifax Centre and has grown to include participants from other astronomy clubs in the Atlantic region, and a number of attendees from the northeastern United States.
All participants come to enjoy dark skies on a weekend near the new Moon phase towards the end of summer. Nova East is held at Smiley's Provincial Park, near Windsor, Nova Scotia. A limiting magnitude of +6 is the norm.
Nova East registrants have access to all events, including all talks, workshops and presentations, three nights of observing (weather permitting!), the potluck BBQ, the astronomers' breakfasts and the door prizes draw. Nova East Registrants have onsite parking (if camping) or adjacent site parking (if not camping).
