The Oregon Museum of Science and Industry (OMSI) is getting ready for its largest star party of the year on Monday, August 12, the Perseid Meteor Shower Watch! Hundreds of star lovers from across the Pacific Northwest will be meeting at Rooster Rock State Park at 9 p.m. to watch and enjoy the wonder of the Perseid Meteor Shower. The event, sponsored by OMSI, Rose City Astronomers, and Oregon Parks and Recreations will have telescopes set up for attendees to use. OMSI staff will be presenting informal talks about the meteor shower, constellations, and the summer sky.

The Perseid Meteor Showers are visible throughout the state. If you aren’t able to join us at the party, get away from the city lights and gaze at the sky. Midnight is expected to be the peak time.
