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 web site presents a basic introduction to the cosmic background radiation and cosmology. It includes terms, graphs, and animations to present the key principles and ideas of cosmology, the expansion of the universe, properties of light, the history of the universe since the Big Bang, inflation, the curvature of spacetime, and its implications on the fate of the universe. The presentation ends with a review of the terms and a list of links to other resources. This material is based on a public presentation by the author.
