| These interacting galaxies are reminicent of the much closer
(and famous) example, M51. NGC 7753 and
its companion are more than 200 million light years distant. Note the arm
that the two galaxies share is divided by some interesting mechanism. Both
the companion and NGC 7753 have recent episodes of star formation taking
place. The small galaxy has most likely made a close passage to its larger
neighbor in its orbit. It will either be flung out into the inter-galactic
realm- or more likely it will eventually be consumed by NGC 7753.
