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.
The first of 6 linked web pages on how the inner radiation belt was discovered in 1958 by Van Allen, on the type of instrument used (Geiger counter), on the belt's explanation based on neutron albedo, on radiation belts created by nuclear bombs and on the discovery of the outer belt. This resource is nonmathematical and short; a longer exposition (with references) is also available.
