the 2009 International Year of Astronomy!
In 2009 we celebrate the 400th anniversary of Galileo's first observations of the universe through a telescope. In honor of this early event, the International Astronomical Union (IAU) and the United Nations have proclaimed 2009 as the International Year of Astronomy to spread awareness of astronomy's contributions to society and culture, stimulate young people's interest in science, portray astronomy as a global peaceful endeavor, and nourish a scientific outlook in society.

NASA invites YOU to join us in the celebration of IYA2009. This website will be your portal to exciting NASA resources, events, and opportunities for involvement as we develop our program of regional and national IYA activities for students, teachers, and the public.
>Go Observe!
Make 2009 your year to experience the wonders of the universe! Each month, the NASA "Go Observe!" section will highlight a celestial object that you can locate in the sky. Go outside and look up, attend a Night Sky Network ( star party or a sidewalk astronomy event, or go online and use a MicroObservatory ( robotic telescope to make your own observations of the universe. Come back to their "Go Observe!" articles each month to learn more about each object, and to find tips and resources for making and sharing your own observations.
