Dark Pipe nebula called Barnard 59

A telescope in Chile has captured a spectacular view of a pitch black cloud in deep space, a celestial home to several newborn stars hidden in a nebula named after a smoking apparatus.
The new space photo shows part of the dark Pipe nebula called Barnard 59, a distant nebula that forms the mouthpiece of the celestial pipe after which its parent structure is named. Barnard 59 is between 600 and 700 light-years from Earth in the direction of the constellation Ophiuchus (The Serpent Bearer).

Astronomers used a telescope at the La Silla Observatory operated by the European Southern Observatory in  Chile's high Atacama Desert to snap the new image, which ESO officials said is a textbook example of a so-called dark nebula.
Indeed, the new ESO photo shows Barnard 59 as a dark patch of sky framed by an immense star-filled background. At the center of the image are foggy, smoke-like features illuminated by newborn stars, according to an image description. 
Barnard 59 is just one part of the Pipe nebula. Only when it is joined with four other Barnard objects do they appear to form the complete smoking pipe after which the structure is named.

There is relatively little star formation actually underway inside Barnard 59, when compared to other dark nebulas, ESO officials said. Several asteroids, which are actually in the foreground in our own solar system, also appear as blue, green and red stripes, they added.
The Pipe nebula's Barnard 59 structure is named after American astronomer Edward Emerson Barnard, who was the first scientists to systematically observe dark nebulas in through long-exposure space photography, ESO officials explained. In all, Barnard mapped 370 dark nebulas in the sky between the late 19th and early 20th century.
Barnard was also an avid comet-hunter who used the prize money from discovering comets to buy his first house, ESO officials said.
