For centuries people have attempted to prove the existence of planets circling distant stars. On Friday, Sept. 21, at 7:30 p.m. the Fiske Planetarium at the University of Colorado at Boulder will explore the topic.

"Searching for Distant Worlds," a pre-recorded program, will examine recent discoveries of unknown planets around far-away stars and explain why it is so difficult to find these distant objects.

Sommers-Bausch Observatory will be open for telescope viewing immediately following the show at Fiske.

Tickets for the planetarium show are $4 for adults and $3 for seniors and children. They go on sale at 7 p.m. the night of the show. Entrance to the observatory is free.
