A Distant Cluster of Galaxies

Explanation:
In
this 1994
Hubble Space Telescope photograph,
every bright
object is a galaxy.
Oddly - most of them are
spiral galaxies.
This rich
cluster of galaxies, named
CL 0939+4713, is almost half way
across the visible
universe.
Photos like this indicate that
clusters
in the past contained a higher fraction of spirals than do
nearby clusters which are usually dominated by
elliptical galaxies.
