Astronomical association hosts planetarium show 'When Galaxies Collide'
The Battle Point Astronomical Association will present the planetarium show “When Galaxies Collide” at Ritchie Observatory on Saturday, Sept. 8.
Steve Ruhl will look at the types of galaxies that populate the universe and discuss how they are shaped by collisions. Our neighboring galaxy, Andromeda, is heading straight toward our own galaxy at 250,000 mph. At that rate, it will be here in 3 billion to 5 billion years. Find out what happens when it arrives.
The program begins at 7:30 p.m. Admission is free to members of the association; a $2 donation is suggested for nonmembers, $5 for families.
If the sky is clear, astronomers will be on hand with telescopes for public stargazing.
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.
