Like most of the other maria on the Moon, Mare Nubium was named by Giovanni Riccioli, whose 1651 nomenclature system has become standardized. [6] Previously, William Gilbert had included it among the Continens Meridionalis ("Southern Continent") in his map of c.1600, [7] and Michael van Langren had labelled it the Mare Borbonicum (after the House of Bourbon) in his 1645 map.

Sky Above Clouds (1960–1977) is a series of eleven cloudscape paintings by the American modernist painter Georgia O'Keeffe, produced during her late period.The series of paintings is inspired by O'Keeffe's views from her airplane window during her frequent air travel in the 1950s and early 1960s when she flew around the world.
The print shows her as she turns away to come down from the mountain, with the mood of the landscape reflecting her state of mind: the clouds covering the Moon, the wind tugging at her robes, the fence a barrier between her and her lover, and the intertwined pine trees, symbols of conjugal happiness, disappearing in the mist.
1882 chart of the moon with maria. This is a list of maria (large, dark, basaltic plains) on the Moon. It includes other basaltic plains, including the one oceanus as well as features known by the names lacus, palus and sinus. The modern system of lunar nomenclature was introduced in 1651 by Giovanni Battista Riccioli. [1]
The ice crystals responsible for halos are typically suspended in cirrus or cirrostratus clouds in the upper troposphere (5–10 km (3.1–6.2 mi)), but in cold weather they can also float near the ground, in which case they are referred to as diamond dust. The particular shape and orientation of the crystals are responsible for the type of ...
A member of the halo family, moon dogs are caused by the refraction of moonlight by hexagonal-plate-shaped ice crystals in cirrus clouds or cirrostratus clouds. They typically appear as a pair of faint patches of light, at around 22° to the left and right of the Moon, and at the same altitude above the horizon as the Moon.
The ages of the mare basalts have been determined both by direct radiometric dating and by the technique of crater counting.The radiometric ages range from about 3.16 to 4.2 billion years old (Ga), [4] whereas the youngest ages determined from crater counting are about 1.2 Ga. [5] Updated measurements of samples collected by the Chang’e-5 mission show that some lunar basalts could be as ...
