Cebrenia Quadrangle
The Cebrenia quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The quadrangle is located in the northeastern portion of Mars’ eastern hemisphere and covers 120° to 180° east longitude (180° to 240° west longitude) and 30° to 65° north latitude. The quadrangle uses a Lambert conformal conic projection at a nominal scale of 1:5,000,000 (1:5M). The Cebrenia quadrangle is also referred to as MC-7 (Mars Chart-7). It includes part of Utopia Planitia and Arcadia Planitia. The southern and northern borders of the Cebrenia quadrangle are approximately and wide, respectively. The north to south distance is about (slightly less than the length of Greenland). The quadrangle covers an approximate area of 4.9 million square km, or a little over 3% of Mars’ surface area. Origin of name Cebrenia is a telescopic albedo feature centered on 50° N and 150° E on Mars. The feature is named ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mars
Mars is the fourth planet from the Sun and the second-smallest planet in the Solar System, only being larger than Mercury. In the English language, Mars is named for the Roman god of war. Mars is a terrestrial planet with a thin atmosphere (less than 1% that of Earth's), and has a crust primarily composed of elements similar to Earth's crust, as well as a core made of iron and nickel. Mars has surface features such as impact craters, valleys, dunes and polar ice caps. It has two small and irregularly shaped moons, Phobos and Deimos. Some of the most notable surface features on Mars include Olympus Mons, the largest volcano and highest known mountain in the Solar System and Valles Marineris, one of the largest canyons in the Solar System. The Borealis basin in the Northern Hemisphere covers approximately 40% of the planet and may be a large impact feature. Days and seasons on Mars are comparable to those of Earth, as the planets have a similar rotation period a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hibernia
''Hibernia'' () is the Classical Latin name for Ireland. The name ''Hibernia'' was taken from Greek geographical accounts. During his exploration of northwest Europe (c. 320 BC), Pytheas of Massalia called the island ''Iérnē'' (written ). In his book ''Geographia'' (c. 150 AD), Claudius Ptolemaeus ("Ptolemy") called the island ''Iouerníā'' (written , where "ου"/''ou'' stands for ''w''). The Roman historian Tacitus, in his book '' Agricola'' (c. 98 AD), uses the name Hibernia. ''Iouerníā'' was a Greek rendering of the Q-Celtic name *''Īweriū'', from which eventually arose the Irish names '' Ériu'' and '' Éire''. The name was altered in Latin (influenced by the word '' hībernus'') as though it meant "land of winter", although the word for winter began with a long 'i'. Post-Roman usage The High King Brian Boru (c. 941–1014) based his title on being Emperor of the Scoti, which was in Latin ''Imperator Scottorum'', emperor of the Gaels. From 1172, the Lord ...

River Boyne
The River Boyne ( ga, An Bhóinn or ''Abhainn na Bóinne'') is a river in Leinster, Ireland, the course of which is about long. It rises at Trinity Well, Newberry Hall, near Carbury, County Kildare, and flows towards the Northeast through County Meath to reach the Irish Sea between Mornington, County Meath, and Baltray, County Louth. Names and etymology This river has been known since ancient times. The Greek geographer Ptolemy drew a map of Ireland in the 2nd century which included the Boyne, which he called (''Bouwinda'') or (''Boubinda''), which in Celtic means "white cow" ( ga, bó fhionn). During the High Middle Ages, Giraldus Cambrensis called it the ''Boandus''. In Irish mythology it is said that the river was created by the goddess Boann and Boyne is an anglicised form of the name. In other legends, it was in this river where Fionn mac Cumhail captured Fiontán, the Salmon of Knowledge. The Meath section of the Boyne was also known as ''Smior Fionn Feidhli ...

Ireland
Ireland ( ; ga, Éire ; Ulster Scots dialect, Ulster-Scots: ) is an island in the Atlantic Ocean, North Atlantic Ocean, in Northwestern Europe, north-western Europe. It is separated from Great Britain to its east by the North Channel (Great Britain and Ireland), North Channel, the Irish Sea, and St George's Channel. Ireland is the List of islands of the British Isles, second-largest island of the British Isles, the List of European islands by area, third-largest in Europe, and the List of islands by area, twentieth-largest on Earth. Geopolitically, Ireland is divided between the Republic of Ireland (officially Names of the Irish state, named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom. As of 2022, the Irish population analysis, population of the entire island is just over 7 million, with 5.1 million living in the Republic of Ireland and 1.9 million in Northern Ireland, ranking it the List of European islan ...

Valleys And Canyons On Mars
A valley is an elongated low area often running between hills or mountains, which will typically contain a river or stream running from one end to the other. Most valleys are formed by erosion of the land surface by rivers or streams over a very long period. Some valleys are formed through erosion by glacial ice. These glaciers may remain present in valleys in high mountains or polar areas. At lower latitudes and altitudes, these glacially formed valleys may have been created or enlarged during ice ages but now are ice-free and occupied by streams or rivers. In desert areas, valleys may be entirely dry or carry a watercourse only rarely. In areas of limestone bedrock, dry valleys may also result from drainage now taking place underground rather than at the surface. Rift valleys arise principally from earth movements, rather than erosion. Many different types of valleys are described by geographers, using terms that may be global in use or else applied only locally. ...
