Cascade Astronomy Festival

This weeklong celebration in Central Oregon will support Cascade Astronomy and Rocketry Academy’s (CARA) educational programs.

The Cascade Astronomy Festival brings together space science professionals, amateur astronomers, educators, and public young and old for a stellar experience in Central Oregon.  Celebrate the beauty of the dark night sky and the awe & wonder of space. Come see why so many people enjoy the dark skies of Central Oregon.

Novices and experts alike will enjoy daily family-friendly activities and evening presentations with special guest speakers. Programs include tours of local observatories, solar observing opportunities, guest speakers and public stargazing activities. For those serious amateur astronomers looking for a dark sky location, we have that too, with a spot for camping in Brothers, 40 miles east of Bend, Oregon.
