[2] Crepuscular rays usually appear orange because the path through the atmosphere at dawn and dusk passes through up to 40 times as much air as rays from a high Sun at noon.
Cloud decks in parallel bands of latitude at and below the tropopause alternately composed of ammonia crystals and ammonium hydrosulfate. Cirriform Bands of cloud resembling cirrus located mainly in the highest of three main layers that cover Jupiter. [28] Stratiform and stratocumuliform Wave and haze clouds that are seen mostly in the middle ...
The Great Rift covers one third of the Milky Way, and is flanked by strips of numerous stars, such as the Cygnus Star Cloud. [2] West of the Cepheus Clouds, the Funnel cloud/Le Gentil 3 and the bordering North America Nebula, the Great Rift starts with the Northern Coalsack at the constellation of Cygnus, where it is known as the Cygnus Rift.

Glory around the shadow of a plane. The position of the glory's centre shows that the observer was in front of the wings. A glory is an optical phenomenon, resembling an iconic saint's halo around the shadow of the observer's head, caused by sunlight or (more rarely) moonlight interacting with the tiny water droplets that comprise mist or clouds.
