Pairs in Collison
Today's Astronomy Picture of the Day shows NGC 4567 and NGC 4568 in the rich Virgo Galaxy Cluster (NGC 4564 also is in the view). More than just being a pair of spirals, they are a pair that is "interacting" with each other. Galaxies in Collision! Sounds dramatic! Well, in actuality, it's a lot slower and a lot less dramatic as a result in the short term. Over the long term, both galaxies can end up dramatically altered.
