Star War
A star war was a decisive conflict between rival polities of the Maya civilization during the first millennium AD. The term comes from a specific type of glyph used in the Maya script, which depicts a star showering the earth with liquid droplets, or a star over a shell. It represents a verb but its phonemic value and specific meaning have not yet been deciphered. The name "star war" was coined by the epigrapher Linda Schele to refer to the glyph, and by extension to the type of conflict that it indicates. Examples Maya inscriptions assign episodes of Maya warfare to four distinct categories, each represented by its own glyph. Those accorded the greatest significance by the Maya were described with the "star war" glyph, representing a major war resulting in the defeat of one polity by another. This represents the installation of a new dynastic line of rulers, complete dominion of one polity over another, or a successful war of independence by a formerly dominated polity. Losing ...

Maya Civilization
The Maya civilization () of the Mesoamerican people is known by its ancient temples and glyphs. Its Maya script is the most sophisticated and highly developed writing system in the pre-Columbian Americas. It is also noted for its art, architecture, mathematics, calendar, and astronomical system. The Maya civilization developed in the Maya Region, an area that today comprises southeastern Mexico, all of Guatemala and Belize, and the western portions of Honduras and El Salvador. It includes the northern lowlands of the Yucatán Peninsula and the highlands of the Sierra Madre, the Mexican state of Chiapas, southern Guatemala, El Salvador, and the southern lowlands of the Pacific littoral plain. Today, their descendants, known collectively as the Maya, number well over 6 million individuals, speak more than twenty-eight surviving Mayan languages, and reside in nearly the same area as their ancestors. The Archaic period, before 2000 BC, saw the first developments ... [...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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
La Corona
La Corona is the name given by archaeologists to an ancient Maya court residence in Guatemala's Petén department that was discovered in 1996, and later identified as the long-sought "Site Q", the source of a long series of unprovenanced limestone reliefs of exceptional artistic quality. The site's Classical name appears to have been Sak-Nikte' ('White-Flower'). The search for 'Site Q' During the 1960s looted Maya reliefs referring to a then-unknown city surfaced on the international art market. One of these reliefs, showing a ball player, is now in the Chicago Art Institute; another is in the Dallas Museum of Art. Peter Mathews, then a Yale graduate student, dubbed the city "Site Q" (short for ''¿Qué?'' panish for "what?". Some researchers believed that the inscriptions referred to Calakmul, but the artistic style of the artifacts was different from anything that had been found there. Santiago Billy and Carlos Catalan, environmentalists studying scarlet macaws, came upon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palenque
Palenque (; Yucatec Maya: ), also anciently known in the Itza Language as Lakamhaʼ ("Big Water or Big Waters"), was a Maya city state in southern Mexico that perished in the 8th century. The Palenque ruins date from ca. 226 BC to ca. 799 AD. After its decline, it was overgrown by the jungle of cedar, mahogany, and sapodilla trees, but has since been excavated and restored. It is located near the Usumacinta River in the Mexican state of Chiapas, about 130 km (81 mi) south of Ciudad del Carmen, above sea level. It averages a humid 26°C (79°F) with roughly of rain a year. Palenque is a medium-sized site, smaller than Tikal, Chichen Itza, or Copán, but it contains some of the finest architecture, sculpture, roof comb and bas-relief carvings that the Mayas produced. Much of the history of Palenque has been reconstructed from reading the hieroglyphic inscriptions on the many monuments; historians now have a long sequence of the ruling dynasty of Palenque in the 5th century ...

Dos Pilas
Dos Pilas is a Pre-Columbian site of the Maya civilization located in what is now the department of Petén, Guatemala. It dates to the Late Classic Period, and was founded by an offshoot of the dynasty of the great city of Tikal in AD 629 in order to control trade routes in the Petexbatún region, particularly the Pasión River.Salisbury, Koumenalis & Barbara Moffett 2002. In AD 648 Dos Pilas broke away from Tikal and became a vassal state of Calakmul, although the first two kings of Dos Pilas continued to use the same emblem glyph that Tikal did.Webster 2002, p. 263. It was a predator state from the beginning, conquering Itzan, Arroyo de Piedra and Tamarindito. Dos Pilas and a nearby city, Aguateca, eventually became the twin capitals of a single ruling dynasty. The kingdom as a whole has been named as the Petexbatun Kingdom, after Lake Petexbatún, a body of water draining into the Pasión River. Dos Pilas gives an important glimpse into the ...

Maya Calendar
The Maya calendar is a system of calendars used in pre-Columbian Mesoamerica and in many modern communities in the Guatemalan highlands, Veracruz, Oaxaca and Chiapas, Mexico. The essentials of the Maya calendar are based upon a system which had been in common use throughout the region, dating back to at least the 5th century BC. It shares many aspects with calendars employed by other earlier Mesoamerican civilizations, such as the Zapotec and Olmec and contemporary or later ones such as the Mixtec and Aztec calendars. By the Maya mythological tradition, as documented in Colonial Yucatec accounts and reconstructed from Late Classic and Postclassic inscriptions, the deity Itzamna is frequently credited with bringing the knowledge of the calendrical system to the ancestral Maya, along with writing in general and other foundational aspects of Mayan culture. Overview The Maya calendar consists of several cycles or ''counts'' of different lengths. The 260-day count is known to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Retrograde And Prograde Motion
Retrograde motion in astronomy is, in general, orbital or rotational motion of an object in the direction opposite the rotation of its primary, that is, the central object (right figure). It may also describe other motions such as precession or nutation of an object's rotational axis. Prograde or direct motion is more normal motion in the same direction as the primary rotates. However, "retrograde" and "prograde" can also refer to an object other than the primary if so described. The direction of rotation is determined by an inertial frame of reference, such as distant fixed stars. In the Solar System, the orbits around the Sun of all planets and most other objects, except many comets, are prograde. They orbit around the Sun in the same direction as the sun rotates about its axis, which is counterclockwise when observed from above the Sun's north pole. Except for Venus and Uranus, planetary rotations around their axes are also prograde. Most natural satellites have prograd ...

Solar Eclipse
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring the view of the Sun from a small part of the Earth, totally or partially. Such an alignment occurs during an eclipse season, approximately every six months, during the new moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. In a total eclipse, the disk of the Sun is fully obscured by the Moon. In partial and annular eclipses, only part of the Sun is obscured. Unlike a lunar eclipse, which may be viewed from anywhere on the night side of Earth, a solar eclipse can only be viewed from a relatively small area of the world. As such, although total solar eclipses occur somewhere on Earth every 18 months on average, they recur at any given place only once every 360 to 410 years. If the Moon were in a perfectly circular orbit and in the same orbital plane as Earth, there would be total solar eclipses once a month, at every new moon. Instead, because the Mo ...

Phases Of Venus
The phases of Venus are the variations of lighting seen on the planet's surface, similar to lunar phases. The first recorded observations of them are thought to have been telescopic observations by Galileo Galilei in 1610. Although the extreme crescent phase of Venus has since been observed with the naked eye, there are no indisputable historical pre-telescopic records of it being described or known. Observation The orbit of Venus is 224.7 Earth days (7.4 avg. Earth months 0.4 days. The phases of Venus result from the planet's orbit around the Sun inside the Earth's orbit giving the telescopic observer a sequence of progressive lighting similar in appearance to the Moon's phases. It presents a ''full'' image when it is on the opposite side of the Sun. It is a ''gibbous'' phase when it approaches or leaves the opposite side of the Sun. It shows a ''quarter phase'' when it is at its maximum elongation from the Sun. Venus presents a ''thin crescent'' in telescopic views as it co ...
