The bright star AE Aurigae, visible about lower left of the image center, is so hot that it is blue and emits such energetic light that it causes the surrounding gas to glow. The color of the purple region is a mixture of this red glow from the gas and the blue light emitted by AE Aurigae but reflected by surrounding dust.

The "IC" in its name stands for Index Catalogue, an astronomical catalog of galactic nebulae, star clusters, and galaxies, in which it is listed at the 405th position. It is also known as the Flaming Star Nebula; other catalog names include Caldwell 31 and Sharpless 229. The Flaming Star Nebula, officially known as IC 405, lies about 1,500 light-years away, spanning about 5 light-years.
