Explanation:
Rippling dust and gas lanes give the Flaming Star Nebula its name.
The red and purple colors of the nebula are present in
different regions and are created by different processes.
The bright star AE Aurigae,
visible toward the image right, 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 and
reflection nebula, respectively.
Pictured above, the Flaming Star Nebula, officially known as
IC 405, lies about 1500
light years distant, spans about 5 light years,
and is visible with a small telescope toward the constellation of
Auriga.
