| Comment | First galaxy imaged with my new instrument. The spiral galaxy spans about 100 thousand light-years and is about 30 million light-years distant from the 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. The image also reveals galaxy's young blue star clusters and star forming regions. And 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. |
