There are events scheduled for the whole year around the whole world. Have a look at the international website here:
and for information in Canada:
www.astronomie2009.ca ('cause we're all French, apparently)
To find out what's going on in your local area, just Google your city + IYA and see what comes up! Many communities are hosting their own opening ceremonies this weekend, so take a look!
One very cool thing we're doing in Canada is giving out Galileo Moment cards - these are basically like baseball or hockey cards, but instead of a picture and stats of an athlete, they show a picture and stats of a famous astronomical body (Jupiter for instance). On each card is a registration number, and these cards will be given out at IYA events throughout the year.
When someone receives a card, they can go to Canada's IYA website and register the number on the card, along with their name. Then, in 2010, the Canadian Space Agency will launch a disc with all the names that were registered into space!! That's pretty cool, if you ask me!
I hope that everyone takes advantage of this amazing opportunity to learn more about the universe around us, where we came from, and where we are going!
