Edge-On Spiral Galaxy NGC 891

This is an edge-on picture of the unbarred spiral galaxy NGC 891. An unbarred spiral galaxy is a spiral-shaped galaxy without a central bar formation. It is about 30 million light years away in the constellation Andromeda. NGC 891 was discovered in 1784 by William Herschel. It is similar to the Milky Way, with a disk shape and bulge in the center. Star formation or supernova explosions are likely causes for the streaks of dust that extend outward from the galaxy.
