In the Guts of the Fish

Today's Astronomy Picture of the Day shows NGC 660, the Polar Ring Galaxy, in the constellation of Pisces. A "irregular" galaxy, rather than the more familiar spiral or ellipitcal type, the shape was probably caused by a collison with another galaxy. See also: Arp's Atlas of Peculiar Galaxies for a whole catalog of strange shapes. What mad universe?
