Opened in the fall of 1962 (and formally dedicated in early January 1963 with the name "Bakersfield College Planetarium"), the William M Thomas Planetarium in Math-Science 112 has provided shows for over 4,500 K-12 students per year. The B.C. astronomy and physical science classes also use the planetarium at selected times during the semester.

The upgraded planetarium was named after Rep. Bill Thomas and dedicated on November 2, 2006. Congressman Thomas directed the $1 million in federal funds needed to move the planetarium into the 21st century. See this short video for more about the remodel.
