Large
spiral galaxy NGC 891 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
of stars and a central bulge cut along the middle by regions of
dark obscuring dust. But remarkably apparent in NGC 891's edge-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.
Fainter galaxies can also be seen near the edge-on disk in this
deepportrait of NGC 891.
