The Edgerton Explorit Center has purchased and received a portable planetarium to add to its extensive offering of Edgerton on the Move (EOTM) programs and field trip offerings.   The planetarium will be capable not only of showing the daytime and nighttime sky but also prerecorded full dome planetarium shows.

The planetarium was purchased using funds granted by several generous donors, including B.K. and Norma Heuermann Foundation Fund, Heuermann Family Trust Fund, the Get R Done Foundation, Woodard Trust, Southern Power, Hamilton Telecommunications and an anonymous donor.

The planetarium, made by Digitalis Education Solutions, Inc. of Bremerton, WA, uses Nightshade, a version of the popular freeware astronomy Stellarium ( to depict the sky.  From a computer, images are projected using a video system equipped with a fish-eye lens. With a diameter of five meters, the inflatable dome will have enough room to seat a class of 25 students.  Visitors enter the dome walking in, and the dome is wheelchair accessible. The entire system can be set up in 30 minutes.

“Many people may remember a portable planetarium from back in grade school days, crawling through a tunnel to see dim dots for stars,”  says Edgerton educator and “mad scientist” Dan Glomski.  “They’ve come a long way in the last few years.”

“We couldn’t be more excited to have one of these for Edgerton on the Move,” adds Edgerton Executive Director Mary Molliconi. “We already visit over 150,000 people at schools and libraries across Nebraska and into northern Kansas, and a portable planetarium will make the program even more attractive.”

The planetarium will be part of a series of educational activities and events centered around the August 21, 2017 total solar eclipse, the path of which crosses Nebraska. The Edgerton Center is working with Hall County Convention and Visitors Bureau, Aurora Area Chamber and Development Corporation, NASA Nebraska Space Grant and other organizations to promote viewing this extremely rare event from central and eastern Nebraska.

“Interest in the eclipse will be incredibly high, and we want to make sure people are ready for it,” Glomski says. “The portable planetarium will definitely help us do that.”

The planetarium made its public debut during its Preclipse event held August 21, 2016 (exactly one year before the eclipse). Visitors were invited to see the planetarium, view the Sun with special telescopes and participate in other Sun-related activities.
