NGC4565

NGC 4565 has an angular extension of 14.8′ × 2.1′ and an apparent brightness of 9.5 mag. A slight "warp" can be seen at the edges, which is caused by the rotation of the disc. The galaxies IC 3571 and IC 3579 are located in the optical vicinity of the object.
This image shows the arched central core of the galaxy, intersected by opaque dust trails surrounding NGC 4565 as a thin galactic plane.

NGC 4565 is a giant spiral galaxy more luminous than the Andromeda Galaxy. Much speculation exists in 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 adjudge among various options put forth. However, its exponential shape suggested that it is a barred spiral galaxy. Studies with the help of the Spitzer Space Telescope not only confirmed the presence of a central bar but also showed a pseudobulge within it as well as an inner ring.
NGC 4565 has at least two satellite galaxies, one of which is interacting with it. It has a population of roughly 240 globular clusters, more than the Milky Way. NGC 4565 was discovered on 6 April 1785 by the German-British astronomer Wilhelm Herschel.
