The year 2009 was proclaimed the International Year of Astronomy by the United Nations, an idea that came from the International Astronomy Union (IAU) which this way wanted to commemorate certain important anniversaries. To begin with, it was 400 years ago that Galileo first used a telescope to gaze at the sky. The invention was a breakthrough and the discoveries it allowed are now the foundations of astronomy. Also in 2009, 40 years will have passed since the first man set foot on the Moon, and 90 years since the IAU was established.
