IC410 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 NGC1893 that lies in the center of the nebula. This star cluster is about 4 million years old, but in astronomical terms it is still very young, with hot, massive stars. At the top-right of the star cluster two more dense structures are visible. As can be seen in the picture, these structures point away from the center of the nebula. Due to these structure’s shape, the nebula is also called the Tadpoles Nebula.
