This pair of galaxies often goes by the
nickname of the "Cocoon Galaxy." Each "blob" is actually a
spiral galaxy that has been distorted by the other. Hints of
spiral structure are still evident in the smaller galaxy. These
galaxies have already passed their closest approach (perigalacticon)
and are now speeding away from each other. A tail of stars
stretches between the galaxies which are separated by at least
24,000 light years. All of this action takes place 40-50 million
light years away. These interacting galaxies make a good
real-world example for astronomers to compare computer models
(simulations) of galactic collisions. Note the incredible number
of starforming regions that have developed along facing sides of
each galaxy.
