Join astronomer Dave Fong as he examines the worlds outside our solar system that may be habitable at the planetarium show “Habitable Exoplanets” at 8 p.m. Saturday, Aug. 9 at the Edwin E. Ritchie Observatory.

If the sky is clear, astronomers will be on hand with telescopes for public solar viewing prior and star-gazing afterward.

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

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, 11299 Arrow Point Drive NE.
