We'll start this after-hours party indoors by making paper airplanes to soar off the library balcony and other activities. Then at 8 p.m., we'll move outside where we hope clear skies will allow us to see Jupiter, Mars and Saturn through a telescope. At this time of year, Mars is closer to the Earth, so it will be one of the "stars" of the night. If the weather is cloudy, we'll stay inside for a presentation about these planets and tips on how to see them yourself. Hosted by Val Germann and co-sponsored by the Central Missouri Astronomical Association. Enter through the Gene Martin Secret Garden at the west end of the main parking lot. Ages 6-adult.
