NGC4565 (also known as the Needle galaxy or Caldwell 38) is an edge-on spiral galaxy about 30 to 50 million light-years away in the constellation Coma Berenices.
It is known as the Needle Galaxy for its narrow profile. First spotted in 1785 by Sir William Herschel (1738–1822), it is one of the most famous examples of an edge-on spiral galaxy.
NGC4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy and it has been proposed that if it were viewed face-on, it would be the most spectacular of the galaxies of its type in the nearby Universe.
