IC 405 Flaming Star Nebula

IC 410 Tadpole Nebula

IC 417 Bright Nebula

Auriga

 

The Flaming Star Nebula in the upper right of the photo (north is up) is part of a dust cloud illuminated by the "runaway" star AE Aurigae.  This bright star is a transient visitor to this region and is thought to be ejected from the Orion Nebula by the collision of two binary star groups.  Ultraviolet radiation from the star ionizes and excites hydrogen gas and causes the gas cloud to glow red.  A smaller region closer to the star shines blue, due to dust reflecting the starlight.  The Tadpole Nebula is visible in the lower left center of the photo and contains the open cluster NGC 1893 and was discovered long before the surrounding emission nebula IC 410.  The stellar wind from these young stars sculpts some of the nebula's gas and dust into two "tadpoles" at the upper left of the gas cloud...although difficult to see at this scale.   Lastly, IC417 is the small bright nebula seen in the far upper left of the image.
