Explanation:
Galaxies
abound in this well-chosen field of view that spans
about 1 degree on the sky toward the northern constellation Andromeda.
At top right is large spiral galaxy NGC 891, 100 thousand light-years
across and seen almost exactly edge-on.
About 30 million light-years distant, NGC 891 looks a lot like our own
Milky Way with a flattened, thin, galactic disk.
Its disk and central bulge are cut
along the middle by dark,
obscuring dust clouds.
Scattered toward the lower left, and beyond a foreground of Milky Way
stars, are members of
galaxy
cluster Abell 347.
Nearly 240 million light-years away,
Abell 347 shows off its own
large galaxies in the sharp telescopic image.
They are similar to NGC 891 in physical size but located almost
8 times farther away, so Abell 347 galaxies have roughly one eighth the
apparent size
of NGC 891.
