In 1609, Galileo Galili , 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.
