The International Year of Astronomy 2009 (IYA2009) is a global celebration of astronomy and its contributions to society and culture and marks the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei.

In 1609, Galileo Galilei, an Italian scientist, performed the first observation of the "stars" using a telescope. The Moon was covered with craters, the Milky Way was made of numerous stars, satellites circulated Jupiter, Venus waxed and waned...
Even with a small telescope, only 4cm in diameter, Galileo found the sky filled with surprises that overturned the human understanding of the universe. In this "You are Galileo" project, you will use a telescope similar to Galileo' s and re-discover the surprises that Galileo found.
Take part in this project reading the brochure.
