Description

This is a really beautiful object to for me. It’s one of the jewels that you can find in gamma Cygni nebula. I hope you enjoy.

“A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds.” (wiki)
