An early cloudscape photographer, Belgian photographer Léonard Misonne (1870–1943), was noted for his black and white photographs of heavy skies and dark clouds. [ 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).
As in all real images from our Arm of the galaxy much is obscured by the Great Rift, dark dust clouds that span from Cygnus to Centaurus. In astronomy , the Great Rift (sometimes called the Dark Rift or less commonly the Dark River ) is a dark band caused by interstellar clouds of cosmic dust that significantly obscure ( extinguish ) the center ...
Clouds of the genus nimbostratus tend to bring constant precipitation and low visibility. This cloud type normally forms above 2 kilometres (6,600 ft) [10] from altostratus cloud but tends to thicken into the lower levels during the occurrence of precipitation. The top of a nimbostratus deck is usually in the middle level of the troposphere.
Through the use of convolutional neural networks, [6] an IRDC catalog consisting of 18,845 items was created by two astronomers named Jyothish Pari and Joe Hora, who created a computer algorithm which could efficiently scan the images created by the Spitzer telescope’s IRAC camera to find infrared dark clouds.

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.

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.
A nimbostratus cloud is a multilevel, amorphous, nearly uniform, and often dark-grey cloud that usually produces continuous rain, snow, or sleet, but no lightning or thunder. [ 1 ] [ 2 ] [ 3 ] Although it is usually a low-based stratiform cloud, it actually forms most commonly in the middle level of the troposphere and then spreads vertically ...
