NGC891 LRGB Galaxy

NGC891 is a unbarred spiral galaxy in the constellation Andromeda. It is approximately 30 million light years away. It was discovered by William Herschel on October 6 1784. Although this galaxy looks as we think our own galaxy would look like when viewed edge-on, recent high-resolution images of its dusty disk show unusual filamentary. These patterns are extending into the halo of the galaxy, away from its galactic disk. Scientists presume that supernova explosions caused this interstellar dust to be thrown out of the galactic disk toward the halo. The galaxy is a member of the NGC 1023 group of galaxies in the Local Supercluster.
