Join us 12-11 pm and tour the 172-year-old Observatory, view our exhibits, and participate in hands-on astronomy activities. And if weather permits, view the sun with our solar telescope and the night sky with historic and modern telescopes. Telescope observing is weather permitting, but we always strive to have fun things to do!

Families welcome, admission is always free, and registration is not required.
