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.
Thomas Arny's collection of online tutorials at the University of Massachusetts span a range of astronomy-related topics. Tutorial subjects include gravity, escape velocity, seasons, orbits, the properties of stars, and galaxies. Each tutorial has questions interspersed to allow students to assess their learning about the presented subject.
