IC 410 Tadpole Nebula - the Full Frame
There is a later version of The Tadpoles: HERE
The nebula is commonly known as the Tadpole Nebula for the ‘tadpole-like’ structures of dense, cooler gas that are being shaped by the intense radiation from the hot stars of the young open cluster NGC 1893, embedded in the nebulosity.
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.
