Description

NGC 4565, also known as the Needle Galaxy or Caldwell 38, is the largest edge-on spiral galaxy in the night sky. It is quite similar to our Milky Way, although NGC 4565 is slightly more massive (our Galaxy has a mass of about eight hundred billion suns). The Needle Galaxy contains at least two hundred globular clusters and is thought to have a dark matter halo with a mass of several hundred billion suns).
A dark dust lane runs the entire length of the galaxy, masking much of the arms’ brightness. The central region features a small bulge, and that is the easiest place to detect the dust lane. The dark streak is offset a little to the north of center because NGC 4565 is inclined to an angle of 87°, 3° from edge-on.
