The United Nations has declared 2009 as International Year of Astronomy, which in words of the president of the International Astronomical Union “provides all nations the chance to participate in an exciting scientific and technological revolution”. The proposal to celebrate the International Year of Astronomy has been made by the Italian government to commemorate the 400th anniversary of the first use of an astronomical telescope by Galileo Galilei. This Italian physicist and astronomer built a telescope in 1609 which gave way to a scientific revolution that changed the vision of the world. Discoveries such as Jupiter’s satellites, the phases of Venus, the mountains and craters of the moon or the rotation of the Sun over its own axis are some of his discoveries. This year, German astronomer Johannes Kepler described in Astronomía nova the fundamental laws of celestial mechanics.
