Wisconsin Science Festival – Night Science (Inflatable Planetarium, Observatory, Owls)

Thursday October 11 @ 6:00 pm - 9:30 pm

Join Beaver Creek Reserve and CESA 10 for an amazing evening of science at the reserve. Start your night by entering the STARLAB, CESA 10’s inflatable interactive planetarium. Let your imagination take over as you hear stories under the ‘stars’ and explore how the night sky changes each night and through the seasons.

After dark you can head to Hobbs Observatory on the Beaver Creek grounds to get an up close view of the real night sky as the moon, stars, planets and galaxies come into view. You can walk next door to the Citizen Science Center and watch as researchers trap and band Wisconsin’s tiniest owl, the secretive Saw-whet. We may even be lucky enough to get a visit from a naturalist with Beaver Creek’s resident teaching owl.

You are invited to join us for all or part of this exciting event. This event is appropriate for all ages.

Schedule for the evening:

6 – 9 p.m. STARLAB in the auditorium, located in the Wise Nature Center building. CESA 10’s astronomy expert, Joan Neumann, will lead programs. Programs begin on the half hour. Rain or shine.

After dark (beginning approximately 7:30 p.m.) Public viewing and telescopes, Hobbs Observatory. Chippewa Valley Astronomical Society will be on hand to answer questions. Weather permitting.

After dark (beginning approximately 7:30 p.m.) Saw-whet owl banding, Citizen Science Center. Weather permitting.
