An emission nebula IC 410 lies about 12,000 light-years away in the constellation Auriga. The cloud of glowing hydrogen 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, the bright cluster stars are seen just below the prominent dark dust cloud near picture center. Notable near the 7 o’clock position in this wide, detailed view 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.
Rich in star clusters and nebulae, the ancient constellation of Auriga, the Charioteer, rides high in northern winter night skies. Spanning nearly 24 full moons (12 degrees) on the sky, this deep telescopic mosaic view recorded in January shows off some of Auriga’s most popular sights for cosmic tourists. The crowded field sweeps along the plane of our Milky Way galaxy in the direction opposite the galactic center. Need directions? Near the bottom of the frame, at the Charioteer’s boundary with Taurus the Bull, the bright bluish star Elnath is known as both Beta Tauri and Gamma Aurigae. On the far left and almost 300 light-years away, the busy, looping filaments of supernova remnant Simeis 147 cover about 150 light-years. Look toward the right to find emission nebula IC 410, significantly more distant, some 12,000 light-years away. Star forming IC 410 is famous for its embedded young star cluster, NGC 1893, and tadpole-shaped clouds of dust and gas. The Flaming Star Nebula, IC 405, is just a little farther along. Its red, convoluted clouds of glowing hydrogen gas are energized by hot O-type star AE Aurigae. Two of our galaxy’s open star clusters, Charles Messier’s M36 and M38 line up in the starfield above, familiar to many binocular-equipped skygazers.
The Tadpole Nebula (IC 410) is an emission nebula around an open star cluster (NGC 1893). The “tadpoles” are clumps of gas and dust from the formation of the cluster. Inside them, new stars are born. The tails from the “tadpoles” are caused by the solar wind of the stars of NGC 1893 (that’s why the point away from the star cluster).
