With this applet you can study how galaxies collide and merge gravitationally and how the effects of the collision depend on the properties of the galaxies. You can also recreate collisions between real interacting galaxies observed in the sky.</langstring></description><keyword><langstring xml:lang="en">galaxies collision</langstring></keyword></general><lifecycle><status><source>LOM v1.0</source><value>final</value></status><version><langstring xml:lang="en">1.0</langstring></version><contribute><role><source>LOM v1.0</source><value>author</value></role><date><datetime>2008-10-12</datetime><description/></date><centity><vcard>Scientific Development: Chris Mihos (CWRU), Greg Bothun (UOregon)
