"First Light" is a live, interactive tour of the night sky and includes a look at the summer constellations and an examination of their stories.

The show is scheduled to begin at 7 p.m. in the Donald E. Bianchi Planetarium in Science Building II near the center of the campus at 18111 Nordhoff St. in Northridge.

"It should be an interesting night," said Christopher McGowan, program coordinator for the planetarium. "We are the only planetarium offering a show in the San Fernando Valley. This is the first time the university has ever opened up the planetarium to the public for a show, and, if all goes well, we hope to do it again."

In addition to the look at the constellations of a summer night, Jet Propulsion Laboratory astronomer Bob Korechoff will be on hand with new photographs taken by the Hubble Space Telescope and answer questions about new JPL programs.

Weather permitting, the university's Campus Observatory will be open after the lecture for public viewing.

The show is recommended for people ages 8 and above.

CSUN's Donald E. Bianchi Planetarium is operated by the university's Department of Physics and Astronomy. It is named after the founding dean of the College of Science and Mathematics, At the heart of the 105-seat theater is a Spitz-512 Star Projector, capable of recreating the night sky on the planetarium's 40-foot dome with accuracy and brilliance. More than 2,000 stars, the five visible planets and all of their apparent motions in the sky seem to come alive as they are projected overhead.

Tickets to the show are $5 for adults and $3 for students. Tickets are available at the University Student Union Box office Monday through Friday from 9:30 a.m. to 5 p.m., or by calling the box office at (818) 677-2488.
