Barnard 68 is a molecular cloud, dark absorption nebula or Bok globule, towards the southern constellation Ophiuchus and well within the Milky Way galaxy at a distance of about 125 parsecs (407 light-years). [2] It is both close and dense enough that stars behind it cannot be seen from Earth.
Barnard 68, one of the objects listed in the catalogue. Target: Dark nebulae: Named after: ... The nebulae listed by Barnard have become known as Barnard objects. [2]

Bok globules located within the NGC 281 nebula (IC 1590 cluster) Barnard 68 , at a distance of only 410 light-years, is one of the nearest Bok globules. Its diameter is about 12,500 AU (0.198 ly) (≈ 2 trillion km)
An image of Barnard 68, a dark nebula mistakenly used to refer to the Boötes Void.. The Boötes Void has been often associated with images of Barnard 68, [7] a dark nebula that does not allow light to pass through; however, the images of Barnard 68 are much darker than those observed of the Boötes Void, as the nebula is much closer and there are fewer stars in front of it, as well as its ...

Barnard's Loop (catalogue designation Sh 2-276) is an emission nebula in the constellation of Orion. It is part of the Orion molecular cloud complex which also contains the dark Horsehead and bright Orion nebulae. The loop takes the form of a large arc centered approximately on the Orion Nebula. The stars within the Orion Nebula are believed to ...
