The California Academy of Sciences is among the largest museums of natural history in the world. The Academy began in 1853 as a learned society and still carries out a large amount of original research, with exhibits and education becoming significant endeavors of the museum during the 20th century. Completely rebuilt in 2008, the building covers 400,000 square feet (37,000 square metres) and is among the newest natural history museums in the United States. The primary building in Golden Gate Park reopened on September 27, 2008.
Asteroid Day is a global awareness campaign where people from around the world come together to learn about asteroids, the impact hazard they may pose, and what we can do to protect our planet, families, communities, and future generations from future asteroid impacts. Asteroid Day is held each year on the anniversary of the largest impact in recent history, the 1908 Tunguska event in Siberia. Subscribe to our Mailing list
