NGC 4565

NGC 4565 - The Needle Galaxy 1,2

Discovered by William Herschel in 1785

NGC 4565 is located in the constellation Coma Berenices approximately 38 million light years distant.  From our perspective, the galaxy is viewed almost precisely edge on and is commonly referred to as the Needle Galaxy.  NGC 4565 shines relatively brightly with a magnitude +9.5.  Under moderately dark skies, it can be viewed visually in relatively small sized amateur telescopes.

There is some debate as to the structure of NGC 4565, however; it is thought to be a barred spiral galaxy.  Observations conducted with the space based Spitzer infra-red telescope appear to support this classification.

The diameter of the galactic disk has been determined to be about 100,000 light years.  This is comparable to the size of our own Milky Way.  If one were located at the same distance as NGC 4565 and viewed the Milky Way with the same edge on perspective, the view would most likely be much the same as we view NGC 4565.
