Explanation: Dusty emission in the Tadpole nebula, IC 410, lies about 12,000 light-years away in the northern constellationAuriga. The cloud of glowing gas is over 100 light-years across,sculpted bystellar winds and radiation from embedded open star clusterNGC 1893.Formed in the interstellar clouda mere4 million years ago, bright cluster stars are seen all around the star-forming nebula. Notable near the image center are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation in IC 410, thesecosmic tadpoleshapes are about 10 light-years long. The featured image was taken in infrared light by NASA's Wide Field Infrared Survey Explorer (WISE) satellite.
