[ 1 ] In the early to middle 20th century, American photographer Alfred Stieglitz (1864–1946) created a series of photographs of clouds, called "equivalents" (1925–1931).
A dark nebula or absorption nebula is a type of interstellar cloud, particularly molecular clouds, 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.
Paranal Observatory nights. [3] The concept of noctcaelador tackles the aesthetic perception of the night sky. [4]Depending on local sky cloud cover, pollution, humidity, and light pollution levels, the stars visible to the unaided naked eye appear as hundreds, thousands or tens of thousands of white pinpoints of light in an otherwise near black sky together with some faint nebulae or clouds ...
This is a list of dark nebulae (absorption nebulae), also called "dark clouds". The Milky Way as seen by Gaia, with prominent dark features labeled in white, as well as prominent star clouds labeled in black.
The Rho Ophiuchi cloud complex with its main dark nebula Lynds 1688, speckled with its pinkish young stellar objects, just left to HD 147889 surrounded by IC 4603 as the bright area at the center. The red area called Sh2-9 has Sigma Scorpii at its center, and Antares is just outside the picture at the bottom.
An infrared dark cloud (IRDC) is a cold, dense region of a giant molecular cloud. They can be seen in silhouette against the bright diffuse mid-infrared emission from the galactic plane . [ 1 ] [ 2 ]

Cirrus uncinus (V-2) Filaments with up-turned hooks or curls. Cirrus spissatus (V-3) Dense and opaque or mostly opaque patches. Cirrus castellanus (V-4) A series of dense lumps, or "towers", connected by a ...
