The spiral galaxy NGC 891 is a large spiral galaxy spanning about 100,000 light-years. It is located about 30 million light-years from Earth in the direction of the constellation Andromeda. From our perspective, the galaxy is seen almost edge-on, making its appearance particularly interesting.
Structure and Features
- NGC 891 has a thin galactic disk and a central bulge of stars, similar to the structure of our own Milky Way.
- The galaxy is divided into two parts by a band of dark dust that runs through its center.
Dust Filaments
- One of the distinctive features is the presence of dust filaments that stretch for hundreds of light-years above and below the central line of the galaxy.
- These dust structures were probably ejected from the galaxy's disk by supernova explosions or intense star formation processes.
Astronomical Significance
NGC 891 is an interesting object to study because its edge-on view allows astronomers to better understand the structure and dynamics of spiral galaxies. Its dust filaments also provide important clues about processes such as active star formation and dust ejections.
