Auriga is a constellation in the northern celestial hemisphere. Auriga and five other constellations are featured in the Winter Hexagon asterism, with Auriga's Capella serving as one of its vertex. Auriga is a large constellation about 50% the size of Hydra. Its brightest star, Capella, is the sixth brightest star in the night sky. Not only does it have many bright open clusters, Auriga also has the Flaming Star Nebula.
Auriga can be located via the Winter Hexagon asterism through Capella. It is also located relatively close to Taurus, which can be easily distinguished by the Pleiades. Auriga itself forms a rough hexagonal shape which can help to further pinpoint the location of the constellation.
This is a rough drawing of Auriga, with its neighbouring constellations.
Capella is the third brightest star in the nothern celestial hemisphere after Arcturus and Vega. It is one the brightest sources of x-ray in the sky. Although it appears as a single star, Capella is actually a quadruple star system organised in two binary systems. The Flaming Star Nebula is an emission and reflection nebula. An emission nebula is one made of ionized gases which will emit electromagnetic radiation of various wavelengths. A reflection nebula, on the other hand, has interstellar dust which reflects the radiation off nearby stars. The energy from the nearby stars is insufficient to ionize the gas, but enough to give sufficient scattering to make the dust visible.
