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.
This study guide discusses Greek astronomy. It progresses through the dark ages and the Renaissance highlighting Copernicus's contributions to astronomy. There is also animations illustrating the Ptolemaic model and retrograde motion.
