The Flaming Star Nebula
Explanation: Is star AE Aurigae on fire? No. Even though AE Aurigae is named the Flaming Star and the surrounding nebula IC 405 is named the Flaming Star Nebula , and even though the nebula appears to some like a swirling flame , 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 bright star AE Aurigae occurs near the center of the Flaming Star Nebula and is so hot it glows 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 . Captured here three weeks ago, the Flaming Star Nebula is visible near the composite image's center, between the red Tadpole Nebula on the left and blue-tailed Comet ZTF on the right. 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).
