Explanation:
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.
