Explanation:
This beautiful cosmic portrait
features NGC 891.
The spiral galaxy
spans about 100 thousand light-years and is seen almost exactly edge-on
from our perspective.
In fact, about 30 million light-years distant in the constellation
Andromeda,
NGC 891 looks a lot
like our Milky Way.
At first glance, it has a
flat, thin, galactic disk and
a central bulge cut along the middle by
regions of dark obscuring dust.
Also apparent in NGC 891's
ege-on presentation are filaments
of dust
that extend hundreds of
light-years above and below the center line.
The dust has likely been blown out of the disk
by supernova explosions or intense
star formation activity.
Faint neighboring galaxies can also been seen near this galaxy's disk.
