Barnard B92 & B93 - Dark Nebula
Dark Nebula & Star Cluster NGC6603
Barnard Dark Nebula B92 (right) & B93 (left) are dark nebula caused by dense obscuring dust blocking light from more distant stars behind them. B92 is very dense and opaque. A lone 12th-magnitude star seems to be visible inside of M92, but it is really in the foreground. B92 is located at a distance of 10,000 light-years. B92 is sometimes called the Black Hole.
B93 is much more mottled in appearance. It is also located 10,000 light-years away. Both B92 and B93 were cataloged by E. E. Barnard in 1913. The small star cluster in the lower left in NGC 6603. These three objects are estimated to all be 10,000 light years distant from Earth. The general pinkish-reddish hue is the larger emission nebula known as Sharpless 41.
