Spiral Galaxy NGC 300 in Sculptor: A Cosmic Gemstone with Stars & Gas Clouds

This sparkling, colorful gemstone is the spiral galaxy NGC 300 in the constellation Sculptor. It is one of the closest spiral galaxies to Earth, only about 6 million light-years away. Does it really look like this? 

Here is a more standard portrait of it. This unusual image combines the light from the stars and dust within the galaxy with the light from ionized clouds of interstellar gas shown in red (sulphur), green (hydrogen) and blue (oxygen). Combining red and green light in a range of proportions makes yellow or orange light, most visible in the image. Light from other ionized gases is also at work in neon signs, fluorescent tubes and street lights. These massive clouds of ionized gas are typically created by young, massive stars that produce high-energy ultraviolet radiation capable of ionizing the gas. Massive stars are short-lived, compared with lighter stars like our sun, and explode as supernovas at the end of their lives. Colorful clouds in this image could be hiding supernova remnants.

Sculptor is a faint constellation in the southern sky. It represents a sculptor. It was introduced by Nicolas Louis de Lacaille in the 18th century. He originally named it Apparatus Sculptoris (the sculptor's studio), but the name was later shortened.
