Barnard 142 and Barnard 143 are a pair of dark nebulae in Aquila in a rich summer Milky Way star field. B142 is in the center of the frame,and B143 lies below and to the right of it. Dark nebula are clouds of non-luminous dust and gas in space that obscure the stars behind them. The distance to Barnard 142 is estimated to be about 2,000 light years. They are located about 3 degrees northwest of Altair,one of the stars in the Summer Triangle. B142 and B143 get their names from Edwin Emerson Barnard's famous list of dark nebulae that he published in a paper in 1919 in the Astrophysical Journal,On the Dark Markings of the Sky with a Catalogue of 182 such Objects | |
