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.

It's AstroNuts' annual kids' space club fundraiser!

Cloudy or clear, join us for programs including presentations in our Skylab and space-themed arts & crafts (Space Crafts!) and tours of the big telescope.
