This year we're celebrating a very special anniversary. 100 years ago, Carnegie astronomer Edwin Hubble discovered the universe right here in San Gabriel mountains! His breakthrough opened the doors to a new understanding of the cosmos that is still driving discovery today. We are commemorating this centennial with special displays and talks. Come learn about how astronomical history happened in your back yard!! 


Those who register in advance will receive their choice of a VAR! plate keychain, magnet, or sticker.
