The nebula itself is known as IC 410, and is home to a pair of intriguing structures popularly known as the "tadpoles." These are clumps of gas and dust left over from the formation of the cluster, and are likely forming yet new stars within them. The tails of the tadpoles are caused by the radiation pressure and solar wind from the stars of NGC 1893, note how they point away from the star cluster.
