Thousands of planets beyond our solar system have recently been discovered. Join astronomer Dave Fong to explore worlds that may be similar to Earth at the planetarium show “Searching for Habitable Worlds” at 7:30 p.m. Saturday, Oct. 8 at the Edwin E. Ritchie Observatory at Battle Point Park.

The show is free to members of the Battle Point Astronomical Association; $2 donation suggested for nonmembers, $5 for families.

There will also be a Saturn Rings Kids Show from 5 to 7 p.m. with Dr. Erica.

If the sky is clear, astronomers will be on hand with telescopes for public star or sun gazing afterward.

The Battle Point Astronomical Association is a nonprofit amateur astronomy organization that operates the Ritchie Observatory and John H. Rudolph Planetarium in the Helix House at Battle Point Park.
