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.
In 2006, the Hubble Space Telescope was pointed at a nearby collection of galaxies called the Coma Cluster. Using these images, astronomers gained fascinating insights into the evolution of galaxies in dense galactic neighborhoods. In this activity, students will first learn the basics of galaxy classification and grouping, then they get to use some actual HST images to discover the 'morphology-density effect' and make hypotheses about its causes. This is part of a larger collection from McDonald Observatory.
