 This image shows a portion of the faint IC 410 emission nebula in false colors. It also shows two remarkable inhabitants of the luminous gas cloud: the IC 410 “tadpoles”. The picture is a composite of images taken through narrow band filters designed to highlight the different atoms of the nebula. The emission of sulfur atoms is visible in red, hydrogen atoms in green, and oxygen atoms in blue. The nebula, partially obscured by dust in the foreground, surrounds NGC 1893, a young star cluster in the galaxy that excites the glowing gas. The tadpoles, made of cooler, denser gas and dust, are about 10 light years long. Carved by the winds and radiation from the stars in the cluster, their trail points away from the central region of the cluster. IC 410 is located about 12,000 light years from Earth, in the direction of the constellation Cocher.
