The Flaming Star Nebula, officially known as IC405, lies about 1500 light years distant, spans about 5 light years, and is visible in the constellation of Auriga. The red and purple colors of the nebula are present in different regions and are created by different processes. The bright star AE Auriga, visible in the middle of the image, is so hot it is blue, emitting light so energetic it knocks electrons away from surrounding gas. When a proton recaptures an electron, red light is frequently emitted. The purple region's color is a mix of this red light and blue light emitted by AE Aurigae but reflected to us by surrounding dust. The two regions are referred to as emission nebula (30‘x19’) an d reflection nebulae (20’), respectively. The nebulae that mainly surrounds AE Aurigae and gives the impression that the star is burning, hence its name. AE Aur is an erratic variable and one of the runaway stars whose proper motion can be traced back to the area of Orion’s Belt.
