The Planetarium is in continuous use serving students from pre-school through senior citizen. Under the direction of Alicia Robertson, all programs are presented live with active student participation.


During the summer, the William Brish Planetarium is closed, however a summer opportunity is available to students up through 5th grade. The Junior Astronomers Program gives young learners plenty of fascinating activities and information about astronomy. A program booklet is available on the Junior Astronomers Program page of the Planetarium website. Children who complete the booklet over the summer can bring it to the William Brish Planetarium when it reopens and redeem it for:

  • William Brish Planetarium Junior Astronomer certificate
  • William Brish Planetarium Junior Astronomer patch

No special equipment is needed, just curiosity!
