IC 410 is a dusty emission nebula located in the constellation of Auriga at about 12,000 ly from Earth. The gas structures in this picture are lit by the radiation from the open star cluster NGC 1893 that lies in the center of the nebula. This star cluster is about 4 million years old, still relatively very young, with hot, massive stars. Two dense structures, right of center, and are composed of dust and gas left over from the formation of the star cluster. As can be seen in the picture, the "tails" of these structures point away from the center of the nebula. This is because of the stellar winds and radiation pressure from the stars in NGC 1893. Due to these structure's shape, the nebula is also called the Tadpoles Nebula (although, to me, they're more like spermatozoa than tadpoles, but who am I to think I can rename a nebula :P).
