The Flaming Star Nebula (IC405) ranks as one of the showpiece sights in the northern constellation Auriga. This glowing emission nebula gains its energy from the star AE Aurigae, a 6th-magnitude massive blue-white star about 1,500 light years away. This brilliant star, which outshines our Sun by some 30,000 times, blasts out ultraviolet light that ionizes the cloud of hydrogen gas around the star. As the hydrogen atoms reassemble, they emit light at signature wavelengths of red and green light that make these nebulae so beautiful. Most such nebulae are energized by stars that formed within their densest and most opaque regions. But that’s not the case with the Flaming Star Nebula. AE Aurigae did not originate here; it’s just passing by chance through a cold cloud of hydrogen as it hurtles through the Milky Way, far removed from the place it was born [Read more…] about Runaway Stars
