IC 410 and NGC 1893

Explanation: Dusty emission nebula IC 410 lies about 12,000 light-years away in the northern constellation Auriga . The cloud of glowing gas is over 100 light-years across, sculpted by stellar winds and radiation from embedded open star cluster NGC 1893. Formed in the interstellar cloud a mere 4 million years ago, bright cluster stars are seen just below the prominent dark dust cloud near picture center. Notable near the 7 o'clock position are two relatively dense streamers of material trailing away from the nebula's central regions. Potentially sites of ongoing star formation, these cosmic tadpole shapes are about 10 light-years long. Emission from sulfur atoms is shown in red, hydrogen atoms in green, and oxygen in blue hues in this false-color , narrow band composite image .
