Astronomer Steve Ruhl will look at distant galaxies and what they tell us about the universe and its history at the planetarium show “Galaxies Far, Far Away” at 8:30 p.m. Saturday, July 13 at Ritchie Observatory. Ruhl will also reveal what we know about the universe and what we remains a mystery.

If the sky is clear, the group will also check out some deep sky wonders through the telescopes of local astronomers with the Battle Point Astronomical Association.

The talk is free to association members; $2 donation suggested for nonmembers, $5 for families.

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