Rocket through space and sail among billions of stars and galaxies. Utilizing simulation software, Dean Regas will guide guests through a family-friendly exploration of the mind-boggling scale of the universe. Along the way you’ll stop at the Moon and individual planets, then you’ll make the jump to light speed and head to interstellar space and see all the galaxies in the universe.

This event is part of the Observatory's Saturday open house programming. Join us 12-11 pm and tour the historic building, view our exhibits, and participate in hands-on astronomy activities. And if weather permits, you'll be able to view the sun with our solar telescope and the night sky with historic and modern telescopes. Families welcome, admission is always free, and registration is not required.
