Explanation:
Rippling dust and gas lanes give the Flaming Star Nebula its name.
The orange 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 left, 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 (depicted here in orange).
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 here in the
Hubble color
palette, 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 the Charioteer
(Auriga).
