Explanation:
How do clusters of galaxies form and evolve?
To help find out, astronomers continue to study the second closest cluster of galaxies
to Earth: the
Fornax cluster, named for the southern
constellation
toward which most of its galaxies can be found.
Although almost 20 times more distant than our
neighboring Andromeda galaxy,
Fornax is only about 10 percent further that the better known and more populated
Virgo cluster of galaxies.
Fornax has a well-defined central region that contains many galaxies,
but is still evolving.
It has other
galaxy groupings that appear distinct
and have yet to merge.
Seen here, almost every
yellowish splotch on the image is an elliptical galaxy in the
Fornax cluster.
The picturesque barred spiral galaxy
NGC 1365 visible on the lower
right is also a prominent Fornax cluster member.
