A spiral galaxy has a glowing white center and wispy arms of gas that are reddish-brown at the thickest parts and whitish-pink for the smaller arms. The galaxy is surrounded by a bluish-white glow.

C40 (NGC 3626)

This structure is a densely packed region of stars that encompasses the heart of a spiral galaxy. Most galactic bulges host supermassive black holes. The visible, ultraviolet, and infrared observations used to create this image of Caldwell 40 were made using Hubble’s Wide Field Camera 3.
