The International Year of Astronomy 2009 is a global effort initiated by the International Astronomical Union (IAU) and UNESCO to help the citizens of the world rediscover their place in the Universe through the day and night-time sky, and thereby engage a personal sense of wonder and discovery.

This year-long celebration of astronomy, takes place in 2009 to coincide with the 400th anniversary of the first recorded astronomical observations with a telescope by Galileo Galilei and the publication of Johannes Kepler's Astronomia nova in the 17th century

Vision

Everyone should realise the impact of astronomy and other fundamental sciences on our daily lives, and understand how scientific knowledge can contribute to a more equitable and peaceful society. IYA2009 activities are taking place locally, nationally, regionally and internationally.

National Nodes in each country are running activities throughout 2009 which will establish collaborations between professional and amateur astronomers, science centres and science communicators. 136 countries are already involved and well over 140 are expected to participate eventually.

To coordinate this huge global programme and to provide an important resource for the participating countries, the IAU established a central Secretariat and an IYA2009 website (www.astronomy2009.org) as the principal IYA2009 resource for public, professionals and media alike.
