Comment

North is to the right.

IC 410 is at a distance of about 12,000 light-years, toward the constellation Auriga. The emission nebula surrounds NGC 1893, a young star cluster, which energizes the gas. At the upper right are two interesting objects, about 10 light-years long, that are commonly named "The Tadpoles." Their creation by stellar winds and radiation is most evident in that the Tadpole's tails point directly away from the nebula's central star cluster.
