“Tadpoles” of IC 410


This close-up view  shows two remarkable denizens of the glowing gas cloud at the left – the “tadpoles” of IC 410. Partly obscured by foreground dust, the nebula itself surrounds NGC 1893, a young galactic cluster of stars that energizes the glowing gas. Composed of denser, cooler gas and dust, the tadpoles are around 10 light-years long. Sculpted by wind and radiation from the cluster stars, their tails trail away from the cluster’s central region. IC 410 lies some 12,000 light-years away, toward the constellation Auriga. At that distance, this image spans about 70 light-years.
