Every other Friday through Aug. 25, the planetarium will offer visitors a chance to see and learn about the stars, constellations and planets visible in the summer sky.

The show starts at 7:30 p.m. in the planetarium adjacent to Citrus Hall on the east side of the campus at 18111 Nordhoff St. in Northridge. Each show will be followed by telescope viewings of celestial objects at the university's observatory.

Admission for each show is $3 for students and $5 for the general public. Tickets are available at the door prior to show time. Advance ticket purchase is recommended to ensure a seat. To order tickets, call (818) 677-2488.

The Donald E. Bianchi Planetarium, named for the founding dean of the College of Science and Mathematics, is operated by CSUN's Department of Physics and Astronomy. At the heart of its 105-seat theater lies a Spitz-512 Star Projector, capable of recreating the night sky on the 40-foot dome with accuracy and brilliance. More than 2,000 stars, the five visible planets and all of the apparent motions of the sky come alive overhead in a unique and relaxing environment.
