IC-405 – The Flaming Star Nebula

 

Located in the southern part of the constellation of Auriga is a cloud of dust and hydrogen gas that is being illuminated by the bright star AE Auriga. The powerful radiation ionizes the hydrogen gas, causing it to glow red. The blue glow is caused by AE Auriga's intense blue light reflecting off the dust. Astronomers believe AE Auriga originated in the Orion Nebula, and was ejected from it after a close encounter with another star. AE Auriga is moving rapidly throug hIC-405's dust and gas cloud, and in the future will leave it dark again.
