2009 marks the 400th anniversary of Galileo's first astronomical observations. The International Astronomical Union and UNESCO has proclaimed 2009 to be the International Year of Astronomy. Celebrations will take place in the United States and throughout the world. 2009 also marks the 60th anniversary of the first light and first scientific observations for the Hale Telescope on Palomar, giving us extra reasons to celebrate.
At the moment I am in St. Louis, MO attending meetings run by the Astronomical Society of the Pacific and the American Astronomical Society on the International Year of Astronomy. Details about the some of the celebrations will be posted here and on the Palomar Observatory website when they become available. Stay tuned.
