Here are some dark nebulae: 

• Trifid Nebula: A stellar nursery with huge, dark lanes of dust 
• Horsehead Nebula: A small dark nebula in the constellation Orion 
• Barnard 68: Located in Ophiuchus, a region rich in stars 
• Coal Sack nebula: Located near α Crux in the Southern Cross 

Dark nebulae are visible to the naked eye and appear as dark clouds and shapes against brighter stars or other nebulae. They don’t have clear boundaries and usually take on unusual shapes. 

Dark nebulae are most obvious when located in front of a bright emission nebula or in a region that is very rich in stars. 

Dark nebulae can hide the sites of the early stages of star formation. 

What is a dark nebula in space?

Dark Nebula. The dark nebulae are clumps or clouds that become opaque because of their internal dust grains. The form of such dark clouds is very irregular: they have no clearly defined outer boundaries and sometimes take on convoluted serpentine shapes.

What is the dark nebula in Orion?

the Horsehead Nebula

Explanation: One of the most identifiable nebulae in the sky, the Horsehead Nebula in Orion, is part of a large, dark, molecular cloud. Also known as Barnard 33, the unusual shape was first discovered on a photographic plate in the late 1800s

Where are dark nebula located?

They are most obvious when located in front of a bright emission nebula (e.g. the Horsehead nebula in Orion) or in a region that is very rich in stars (e.g. Barnard 68 in Ophiuchus). The most famous example in the southern hemisphere is the Coal Sack nebula near α Crux in the Southern Cross

Who Discovered dark nebula?

astronomer Edward Emerson Barnard

The nebula is named after the American astronomer Edward Emerson Barnard who was the first to systematically record dark nebulae using long-exposure photography and one of those who recognized their dusty nature.
