Mare Imbrium
Mare Imbrium (Latin ''imbrium'', the "Sea of Showers" or "Sea of Rains") is a vast lunar mare, lava plain within the Imbrium Basin on the Moon and is one of the larger craters in the Solar System. The Imbrium Basin formed from the collision of a Protoplanet, proto-planet during the Late Heavy Bombardment. Basaltic lava later flooded the giant Impact crater, crater to form the flat volcanic plain seen today. The basin's age has been estimated using Uranium–lead dating, uranium–lead dating methods to approximately 3.9 billion years ago, and the diameter of the impactor has been estimated to be 250 ± 25 km. The Moon's maria (plural of Lunar mare, mare) have fewer features than other areas of the Moon because molten lava pooled in the craters and formed a relatively smooth surface. Mare Imbrium is not as flat as it would have originally been when it first formed as a result of later events that have altered its surface. Origin Mare Imbrium formed when a proto-planet ...

Montes Carpatus
Montes Carpatus is a mountain range that forms the southern edge of the Mare Imbrium on the Moon. The selenographic coordinates of this range are 14.5° N, 24.4° W, and the formation has an overall diameter of . They were named by astronomer Johann Heinrich von Mädler after the Carpathian Mountains in Central Europe. Description This rugged range generally stretches from west to east. Its western end starts near the crater T. Mayer, with a few low ridges curving northwards towards Euler crater. At the eastern extreme, there is a wide gap where Mare Imbrium in the north meets Mare Insularum to the south. East of this gap, the Montes Apenninus, forming another mountainous range that curves towards the northeast. Most of this range consists of a series of peaks and rises, separated by valleys that have been penetrated by lava flows. None of the peaks have received individual names, unless one includes Mons Vinogradov to the west of the crater Euler. The surface to the north ...

Grove Karl Gilbert
Grove Karl Gilbert (May 6, 1843 – May 1, 1918), known by the abbreviated name G. K. Gilbert in academic literature, was an American geologist. Biography Gilbert was born in Rochester, New York, and graduated from the University of Rochester. During the American Civil War, he was twice listed for the draft, but his name was drawn neither time. In 1871, he joined George M. Wheeler's geographical survey as its first geologist. Rockies geologist Gilbert joined the Powell Survey of the Rocky Mountain Region in 1874, becoming Powell's primary assistant, and stayed with the survey until 1879. During this time he published an important monograph, ''The Geology of the Henry Mountains'' (1877). After the U.S. Geological Survey was created in 1879, he was appointed to the position of Senior Geologist and worked for the USGS until his death (including a term as acting director). Gilbert published a study of the former ancient Lake Bonneville in 1890 (the lake existed during the P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejecta
Ejecta (; ) are particles ejected from an area. In volcanology, in particular, the term refers to particles including pyroclastic rock, pyroclastic materials (tephra) that came out of a explosive eruption, volcanic explosion and magma eruption volcano, volcanic vent, or volcanic crater, crater, has traveled through the air or water, and fell back to the ground surface or seabed, ocean floor. Volcanology Typically in volcanology, ejecta is a result of explosive eruptions. In an explosive eruption, large amounts of volcanic gas, gas are dissolved in extremely viscous lava; this lava froths to the surface until the material is expelled rapidly due to the trapped pressure. Sometimes in such an event a lava plug or volcanic neck forms from lava that solidifies inside a volcano's vent, causing heat and pressure to build up to an extreme with no way to escape. When the blockage breaks and cannot sustain itself any longer, a more violent eruption occurs, which allows materials to be e ...

Mare Imbrium Si Map
A mare is an adult female horse or other equine. In most cases, a mare is a female horse over the age of three, and a filly is a female horse three and younger. In Thoroughbred horse racing, a mare is defined as a female horse more than four years old. The word can also be used for other female equine animals, particularly mules and zebras, but a female donkey is usually called a "jenny". A ''broodmare'' is a mare used for breeding. Reproductive cycle Mares carry their young (called foals) for approximately 11 months from conception to birth, the average range being 320–370 days.Ensminger, M. E. ''Horses and Horsemanship: Animal Agriculture Series.'' Sixth Edition. Interstate Publishers, 1990. p. 156 Usually just one young is born; twins are rare. When a domesticated mare foals, she nurses the foal for at least four to six months before it is weaned, though mares in the wild may allow a foal to nurse for up to a year. The estrous cycle, also known as "season" or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mons La Hire
Mons La Hire is a solitary lunar mountain in the western Mare Imbrium. It is located to the northeast of the crater Euler, and to the west-northwest of Lambert. The selenographic coordinates of this feature are 27.8° N, 25.5° W, and it has a maximum diameter at the base of 25 km. The mountain base has a shape roughly like an arrow head, with the point oriented toward the west-northwest. The peak has a height of 1.5 km above the surface. This feature was named after Philippe de La Hire, a French mathematician and astronomer. Nearby craters Several tiny craters near this mountain have been assigned names by the IAU. These are listed in the table below. Felix and Verne are located to the south of the peak, while the remainder are grouped to the north and northeast. Satellite craters By convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Mons La Hire. La Hire A is on the northeast si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mons Pico
Mons Pico is a solitary Moon, lunar mountain that lies in the northern part of the Mare Imbrium basin, to the south of the dark-floored crater Plato (crater), Plato and on the southern rim of a Palimpsest (planetary astronomy), ghost crater. This peak forms part of the surviving inner ring of the Imbrium basin, continuing to the northwest and with the Montes Teneriffe and Montes Recti ranges, and probably to the southeast with the Montes Spitzbergen. This mountain feature is thought to have been named by Johann Hieronymus Schröter for Pico del Teide on Tenerife. Description Mons Pico forms an elongated feature with a length of 25 kilometers (oriented northwest–southeast) and a width of 15 km. The peak rises to a height of 2.4 km, comparable to the maximum altitude of the Montes Teneriffe. The mountain itself is a very reflective and bright object. Due to its isolated location on the lunar mare, this peak can form prominent shadows when illuminated by oblique sunlight. ...

Montes Spitzbergen
The Montes Spitzbergen (Spitzbergen Mountains) is a solitary mountain chain in the eastern Mare Imbrium of the Moon. It is located about 80 km to the north of the flooded crater Archimedes (crater), Archimedes. The range trends from south to north, consisting of a number of peaks separated by lava-flooded valleys, and has a maximum width of about 25 km. It is thought to be the surviving rim or inner ring of an impact crater that has been buried under magma flows. The range was named by Mary Adela Blagg, Mary Blagg for its resemblance to the jagged terrestrial mountains of the Spitzbergen island group. The name was approved by the International Astronomical Union in 1961.

Montes Archimedes
Montes Archimedes is a mountain range on the Moon. It is named after the nearby crater Archimedes, which in turn is named after the ancient Greek mathematician Archimedes. This group of mountains is located on a plateau in the eastern part of the Mare Imbrium, a lunar mare in the northwest quadrant of the Moon's near side. They are bounded on the eastern side by the Palus Putredinis, a small mare, and to the north by Archimedes. Farther to the south and east lies the impressive Montes Apenninus, a long mountain range. The selenographic coordinate In geometry, a coordinate system is a system that uses one or more numbers, or coordinates, to uniquely determine and standardize the position of the points or other geometric elements on a manifold such as Euclidean space. The coordinates are ...s of this range is 25.3° N, 4.6° W.
