Description

The Flaming Star Nebula, IC 405 (other designations: SH2-229, Caldwell 31) surrounds the variable star AE Aurigae.

The nebula lies at a distance of about 1.500 light years and spans 5 light years across.
Radiation from AE Aurigae causes the gas in IC 405 to glow red, while dust creates the blue reflection nebula near the star.
