description Flaming Star Nebula (IC 405) Overview
The Flaming Star Nebula (IC 405) is a combined emission and reflection nebula in the constellation Auriga, approximately 1,500 light-years from Earth. It is illuminated by the blue runaway star AE Aurigae, which is believed to have been ejected from the Trapezium cluster in the Orion Nebula roughly 2.5 million years ago and is now passing through the surrounding gas and dust. The nebula exhibits both red hydrogen emission and blue dust-scattered starlight, giving it a dual character. AE Aurigae's rapid motion through interstellar material distinguishes this nebula from most others energized by a single central star.
help Flaming Star Nebula (IC 405) FAQ
What star illuminates the Flaming Star Nebula?
The nebula is illuminated by AE Aurigae, a blue runaway star. The star's radiation makes surrounding gas glow while nearby dust reflects its light.
How far away is the Flaming Star Nebula?
IC 405 is approximately 1,500 light-years from Earth. It lies in the constellation Auriga.
Is IC 405 an emission nebula or a reflection nebula?
It is both an emission and a reflection nebula. Ionized gas produces glowing emission, while dust scatters the blue light from AE Aurigae.
Why is IC 405 called the Flaming Star Nebula?
The name comes from the nebula's flame-like appearance around AE Aurigae. The reddish glow and surrounding blue reflection give the region a visually fiery structure.
