One of the major events during the International Year of Astronomy 2009 is an exciting project called the 100 hours of Astronomy. This is a global astronomy event running from the 2 to 5 April, during which there are a variety of events taking place, where you can discover more about the Universe with the rest of the world!

The event will start at 4pm (UK time) with a webcast from the Franklin Institute in Philadelphia, where they will be discussing the original telescopes used by Galileo to observe the heavens. In addition to other live webcasts from science centres around the world, there will be a 24-hour star party and a series of live webcasts from professional astronomers observing at 80 major telescope facilities around the globe.
