Astronomers have long known about Mercury and Venus transits of the Sun. However, this technique, now commonly referred to as the Transit Technique, has been amazingly successful in detecting exoplanets, planets around other stars. To date, nearly 6,000 exoplanets or planetary candidates have been detected, the majority of them using the Transit Technique. This talk will deal with some of the historical observations of Mercury and Venus transits and then summarize the state of current exoplanetary observations.

Westfield Heritage Village hosts its annual Star Party on Friday, May 13th from 7 to 10pm and invites you to experience the wonders of the night sky through the eyes of trained astronomers. Presented in partnership with the Royal Astronomical Society and McMaster University, this dazzling event will provide an opportunity to learn about the night sky through a fun and interactive evening of exploration and discovery.

School's out for Summer! NNTO is thrilled to cap the season with guest speakers from the Royal Ontario Museum! Trivia is based on the ROM's collections and we have some delightfully nerdy things for the raffle. You might also get some goodies on the way in.

Join Sara Mazrouei as she discusses our Moon and how its history is linked to the Earth’s distant past.

New Members orientation program – First Light - Spring 2016

Join us this week if skies are clear!

You are invited to the transit of Mercury viewing party at the E.C. Carr Astronomical Observatory (CAO) in Blue Mountains.  This daytime event is jointly hosted by the Blue Mountains Library and the Royal Astronomical Society of Canada - Toronto Centre and is open to the public. Monday, May 9, 2016.  Arrive any time after 10:00 am.

Here on earth, we can only see two planets pass between us and the Sun - and it doesn't happen every day! The last time we saw Mercury appear to glide across the face of the Sun was in 2006. The next time it happens is 2019. Join us for this special daytime event at the David Dunlap Observatory. The gates will open at 10:00 a.m. If the weather's clear, stop by for a (safe) peek at the Sun through a variety of solar telescopes. We'll be webcasting too! For obvious reasons, the big telescope will not be in use. There's no charge. Just drop by.

Join us at the Ontario Science Centre for Astronomy Week with a special event on Monday—a rare Transit of Mercury. We will be set up on the TELUSCAPE observing pad in front of the Science Centre's entrance with specialized telescopes that are safe to aim at the Sun. http://www.space.com/32476-mercury-transit-may-2016-rare-event.html In the event of inclement weather, a live stream of the event will be presented in the Gemini Room.

Join McMaster's Sidewalk Astronomy in observing a rare astronomical event—the transit of Mercury.

Come out and observe a rare event - a transit of Mercury. Join members of the Mississauga Centre of the Royal Astronomical Society of Canada as they set up telescopes equipped with special filters to provide a safe view of the transit. The transit takes approximately 7.5 hours for the planet Mercury to cross the Sun. It will begin just after 7:15am EDT and will end at 2:40pm EDT. Maximum transit will occur just before 11am EDT.
