IC410 is an emission nebula surrounding the open star cluster NGC1893. Young stars of the cluster provide the source of intense radiation that makes gas of the nebula glow. Dust clouds in the foreground partially obscure the glowing gas. The nebula is most notable for two 10ly long structures resembling tadpoles. They consist of cooler and denser gas and dust shaped by stellar winds and radiation from the cluster stars. New star formation is still going on in the denser areas of the nebula. IC410 is some 12000 ly distant from Earth and has a diameter of more than 100 ly.
