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 page has descriptions and animations from numerical simulations of colliding galaxies. Normal observation shows interacting galaxies apparently frozen in the midst of billion-year-long collisions. These movies transcend a limited view of time by indicating the past and future of such encounters. The web page examines interactions between galaxies, paths of different orbits, and theories of structure.
