As one of the most famous edge-on galaxies NGC 4565, also named Needle Galaxy because of it's narrow appearance, is a showpiece in the constellation Coma Berenices.
This view is displaying a classic feature of spiral galaxies, the bulge of stars near the center of the disk glowing in the yellow light of older stars.
A massive dust lanes within the plain pf the galaxy shows very fine details and blueish areas of star formation.
Recent observations at X-ray wavelengths have revealed powerful x-ray sources arising from the core region of NGC 4565. The major source is consistent with a low luminosity active galactic nucleus (AGN).
AGNs are producing x-rays and other forms of high energy radiation through accreted mass by a supermassive black hole at the center of the galaxy.
The galaxy spans 100 000 light years in diameter and is situated at a distance of 30 million light years. The galaxy to the top left corner is NGC 4562 in the vicinity of NGC 4565.
