Join us online to learn basic astronomy that you can do on your own from your backyard! We'll explain the dance of the inner planets in the evening sky, talk about conjunctions, elongations, and transits, and share some tips for safely viewing the inner planets. Galileo did it - so you can, too!

Join us as we discuss the philosophical definitions of life, the complexities of biosignature, and life as we don’t know it as we reach beyond Earth on our journey to discover if we’re alone in the universe.

Join us for an evening of free public stargazing along the north shore of Lake Ontario at Millennium Square. Observe the Moon, stars, and an excellent opportunity to observe Venus through our telescopes!
