Galilean Nights

On 22-24 October 2009, the new IYA2009 Cornerstone Project, Galilean Nights, will see amateur and professional astronomers around the globe taking to the streets, pointing their telescopes to the wonders that Galileo observed 400 years ago. Galilean Nights follows the unprecedented success of IYA2009's 100 Hours of Astronomy. The event will be spread over three nights during which amateur and professional astronomers will share their knowledge and enthusiasm for space by encouraging as many people as possible to look through a telescope at our planetary neighbours. The focus for Galilean Nights is the objects that Italian astronomer Galileo observed 400 years ago. These include Jupiter and the Moon, which will be well-positioned in the night sky for observing during the event.
