Galaxies are not as isolated in the universe as it may seem;
most galaxies come in clusters, and Abell 194 is a big one, with
over 100 member galaxies. The brightest members of this group (still
a very dim 13th magnitude) are the double galaxies NGC 545 / 547, and
below them in this image NGC 541. You may be able to make out the
envelope of gas that surrounds this group of three, evidence that they
are interacting with one another. You may also spot the unusual blue
bump on the "top" edge of NGC 541; this is "Minkowski's Object," a
dwarf galaxy that is unusual for its high rate of new star formation. Abell
194 is found in the constellation Cetus. This galaxy cluster is about 265
million light years from earth.
