History
The Mt. San Antonio College was opened to the public in the Spring of 1968. This year we are celebrating 50 years of bringing the wonder and excitement of astronomy to the community. The aging planetarium was badly in need of renovations and was closed for several years during the 2000's. Thanks to the generosity of community members, businesses and the Randall's the planetarium reopened it's doors in December 2010 and has been serving students and the community ever since.
