Vucub-Came Macula
Vucub-Came is one of the "Brass Knuckles", a series of equatorial dark regions on Pluto. It is named after Wuquub' Kameh "Seven Death", one of the Quiché death gods in the Popol Vuh. Vucub-Came Macula is the fourth-largest dark spot on Pluto. Its surface is covered with tholin Tholins (after the Greek (') "hazy" or "muddy"; from the ancient Greek word meaning "sepia ink") are a wide variety of organic compounds formed by solar ultraviolet or cosmic ray irradiation of simple carbon-containing compounds such as carbon ...s which give Vucub-Came its brown color. The dark spot is surrounded with tall uplands. Extensive fault systems in this area have formed deep canyons running roughly north–south. References {{Pluto Regions of Pluto ...

Brass Knuckles (Pluto)
The geography of Pluto entails the delineation and characterization of regions on Pluto. Plutonian geography is mainly focused on what is called physical geography on Earth; that is, the distribution of physical features across Pluto and their cartographic representations. On 14 July 2015, the ''New Horizons'' spacecraft became the first spacecraft to fly by Pluto. During its brief flyby, ''New Horizons'' made detailed geographical measurements and observations of Pluto and its moons. Coordinate system orientation Pluto may be defined as having retrograde rotation and an axial tilt of 60 degrees, or prograde rotation and a tilt of 120 degrees. Following the latter convention (the right-hand rule), the hemisphere currently in daylight is the northern one, with much of the southern hemisphere in darkness. This is the convention used by the International Astronomical Union (IAU) and the ''New Horizons'' team, and their maps put the sunlit hemisphere on top. However, older sources may ...

Pluto
Pluto (minor-planet designation: 134340 Pluto) is a dwarf planet in the Kuiper belt, a ring of trans-Neptunian object, bodies beyond the orbit of Neptune. It is the ninth-largest and tenth-most-massive known object to directly orbit the Sun. It is the largest known trans-Neptunian object by volume, by a small margin, but is slightly less massive than Eris (dwarf planet), Eris. Like other Kuiper belt objects, Pluto is made primarily of ice and rock and is much smaller than the inner planets. Compared to Moon, Earth's moon, Pluto has only one sixth its mass and one third its volume. Pluto has a moderately orbital eccentricity, eccentric and inclined orbit, ranging from from the Sun. Light from the Sun takes 5.5 hours to reach Pluto at its average distance (). Pluto's eccentric orbit periodically brings it closer to the Sun than Neptune, but a stable orbital resonance prevents them from colliding. Pluto has moons of Pluto, five known moons: Charon (moon), Charon, the larg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maya Death Gods
The Maya death gods, (also Ah Puch, Ah Cimih, Ah Cizin, Hun Ahau, Kimi, or Yum Kimil) known by a variety of names, are two basic types of death gods who are respectively represented by the 16th-century Yucatec deities Hunhau and Uacmitun Ahau mentioned by Spanish Bishop Landa. Hunhau is the lord of the Underworld. Iconographically, Hunhau and Uacmitun Ahau correspond to the Gods A and A' ("A prime"). In recent narratives, particularly in the oral tradition of the Lacandon people, there is only one death god (called "Kisin" in Lacandon), who acts as the antipode of the Upper God in the creation of the world and of the human body and soul. This death god inhabits an Underworld that is also the world of the dead. As a ruler over the world of the dead (''Metnal'' or ''Xibalba''), the principal death god corresponds to the Aztec deity Mictlāntēcutli. The ''Popol Vuh'' has two leading death gods, but these two are really one: Both are called "Death," but while one is known as "One D ...

Popol Vuh
''Popol Vuh'' (also ''Popol Wuj'' or ''Popul Vuh'' or ''Pop Vuj'') is a text recounting the mythology and history of the Kʼicheʼ people, one of the Maya peoples, who inhabit Guatemala and the Mexican states of Chiapas, Campeche, Yucatan and Quintana Roo, as well as areas of Belize, Honduras and El Salvador. The ''Popol Vuh'' is a foundational sacred narrative of the Kʼicheʼ people from long before the Spanish conquest of the Maya. It includes the Mayan creation myth, the exploits of the Maya Hero Twins, Hero Twins Hunahpú and Xbalanqué, and a chronicle of the Kʼicheʼ people. The name "Popol Vuh" translates as "Book of the Community" or "Book of Counsel" (literally "Book that pertains to the mat", since a woven mat was used as a royal throne in ancient Kʼicheʼ society and symbolised the unity of the community). It was originally preserved through oral tradition until approximately 1550, when it was recorded in writing. The documentation of the ''Popol Vuh'' is credited ...

The New York Times
''The New York Times'' (''the Times'', ''NYT'', or the Gray Lady) is a daily newspaper based in New York City with a worldwide readership reported in 2020 to comprise a declining 840,000 paid print subscribers, and a growing 6 million paid digital subscribers. It also is a producer of popular podcasts such as '' The Daily''. Founded in 1851 by Henry Jarvis Raymond and George Jones, it was initially published by Raymond, Jones & Company. The ''Times'' has won 132 Pulitzer Prizes, the most of any newspaper, and has long been regarded as a national " newspaper of record". For print it is ranked 18th in the world by circulation and 3rd in the U.S. The paper is owned by the New York Times Company, which is publicly traded. It has been governed by the Sulzberger family since 1896, through a dual-class share structure after its shares became publicly traded. A. G. Sulzberger, the paper's publisher and the company's chairman, is the fifth generation of the family to head the pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tholin
Tholins (after the Greek (') "hazy" or "muddy"; from the ancient Greek word meaning "sepia ink") are a wide variety of organic compounds formed by solar ultraviolet or cosmic ray irradiation of simple carbon-containing compounds such as carbon dioxide (), methane () or ethane (), often in combination with nitrogen () or water ().Sarah Hörs"What in the world(s) are tholins?" Planetary Society, July 23, 2015. Retrieved 30 Nov 2016. Tholins are disordered polymer-like materials made of repeating chains of linked subunits and complex combinations of functional groups, typically nitriles and hydrocarbons and their degraded forms such as amines and phenyls. Tholins do not form naturally on modern-day Earth, but they are found in great abundance on the surfaces of icy bodies in the outer Solar System, and as reddish aerosols in the atmospheres of outer Solar System planets and moons. In the presence of water, tholins could be raw materials for prebiotic chemistry (i.e., the non-livin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NASA
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...
