Explanation: Is star AE Aurigae on fire? No. Even though AE Aurigae is named the flaming star, the surrounding nebula IC 405 is named the Flaming Star Nebula, and the region appears to have the color of fire, there is no fire. Fire, typically defined as the rapid molecular acquisition of oxygen, happens only when sufficient oxygen is present and is not important in such high-energy, low-oxygen environments such as stars. The material that appears as smoke is mostly interstellar hydrogen, but does contain smoke-like dark filaments of carbon-rich dust grains. The bright star AE Aurigae, visible toward the right near the nebula's center, is so hot it is blue, emitting light so energetic it knocks electrons away from surrounding gas. When a proton recaptures an electron, light is emitted, as seen in the surrounding emission nebula. The Flaming Star nebula lies about 1,500 light years distant, spans about 5 light years, and is visible with a small telescope toward the constellation of the Charioteer (Auriga).

If you take a moment and click some of the links, they take you to interesting information :)

It is stunning, isn't it? You are very welcome.

Wow! Thanks for posting this!!!

You're very welcome. I'm planning on posting these types of images more regularly so, stay tuned :)


I forget why but I was actually wondering about the technical definition of fire the other day.

Neat indeed!!

And now NASA has provided you with links to two places to find your answer plus theirs. How relevant is that? :)

Just amazing! Thanks so much for posting this!

My pleasure! You post your pretties and I post mine :)

*sigh* I would have loved to be an astro-physicist. Unfortunately, my grasp of all things related the subject eludes me!
