NGC 4565 LRGB

NGC 4565 is an edge-on unbarred spiral galaxy about 20 million light-years away in the constellation Coma Berenices. It is also known as the Needle Galaxy for its narrow profile. First spotted in 1785 by Uranus' discoverer, Sir William Herschel (1738-1822), this is one of the most famous examples of an edge-on spiral galaxy.[ "Visible through a small telescope, some sky enthusiasts consider NGC 4565 to be a prominent celestial masterpiece Messier missed." The 10th magnitude galaxy sits perpendicular to our own Milky Way galaxy and is almost directly above the North Galactic Pole (in the same way Polaris is located above the Earth's North Pole). Much speculation exists in the literature as to the nature of the central bulge. In the absence of clear-cut dynamical data on the motions of stars in the bulge, the photometric data alone cannot choose among various options put forth. However, its exponential shape suggests that it is a barred spiral galaxy. For viewers along the Emerald Coast, this beauty is visible but only from a dark location. Look high to the Northeast.
