The Astronomy Center has provided educational resources to introductory astronomy educators since 2003. Over the past 20 years, the rapid pace of discovery has rendered some of our linked resources obsolete. Thus, the Astronomy Center will be decommissioned on March 1, 2022. Our highest quality resources will be retained on ComPADRE.org.

It also provides a link to an applet illustrating the differences between refraction, reflection, and diffraction and a video on "seeing" produced by the Earth's atmosphere.
