Star Chart
A star chart is a celestial map of the night sky with astronomical objects laid out on a grid system. They are used to identify and locate constellations, stars, nebulae, galaxies, and planets. They have been used for human navigation since time immemorial. Note that a star chart differs from an astronomical catalog, which is a listing or tabulation of astronomical objects for a particular purpose. Tools using a star chart include the astrolabe and planisphere. History Prehistory A variety of archaeological sites and artifacts found are thought to indicate ancient made star charts. The oldest known star chart may be a carved ivory Mammoth tusk, drawn by early people from Asia who moved into Europe, that was discovered in Germany in 1979. This artifact is 32,500 years old and has a carving that resembles the constellation Orion, although it could not be confirmed and could also be a pregnancy chart. German researcher Dr Michael Rappenglueck, of the University of Munich, ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleiades
The Pleiades (), also known as Seven Sisters and Messier 45 (M45), is an Asterism (astronomy), asterism of an open cluster, open star cluster containing young Stellar classification#Class B, B-type stars in the northwest of the constellation Taurus (constellation), Taurus. At a distance of about 444 light-years, it is among the nearest star clusters to Earth and the nearest Messier object to Earth, being the most obvious star cluster to the naked eye in the night sky. It is also observed to house the reflection nebula NGC 1432, an HII region. Around 2330 BC it marked the vernal point. Due to the brightness of its stars, the Pleiades is viewable from most areas on Earth, even in locations with significant light pollution. The cluster is dominated by OB star, hot blue luminous stars that have formed within the last 100 million years. Reflection nebulae around the brightest stars were once thought to be leftover material from their formation, but are now considered likely to be an u ...

Babylonian Astronomy
Babylonian astronomy was the study or recording of celestial objects during the early history of Mesopotamia. The numeral system used, sexagesimal, was based on 60, as opposed to ten in the modern decimal system. This system simplified the calculating and recording of unusually great and small numbers. During the 8th and 7th centuries BC, Babylonian astronomers developed a new empirical approach to astronomy. They began studying and recording their belief system and philosophies dealing with an ideal nature of the universe and began employing an internal logic within their predictive planetary systems. This was an important contribution to astronomy and the philosophy of science, and some modern scholars have thus referred to this approach as a scientific revolution. This approach to astronomy was adopted and further developed in Greek and Hellenistic astrology. Classical Greek and Latin sources frequently use the term Chaldeans for the philosophers, who were cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babylonian Star Catalogues
Babylonian astronomy collated earlier observations and divinations into sets of Babylonian star catalogues, during and after the Kassite rule over Babylonia. These star catalogues, written in cuneiform script, contained lists of constellations, individual stars, and planets. The constellations were probably collected from various other sources. The earliest catalogue, ''Three Stars Each'', mentions stars of Akkad, of Amurru, of Elam and others. Various sources have theorized a Sumerian origin for these Babylonian constellations, but an Elamite origin has also been proposed. A connection to the star symbology of Kassite kudurru border stones has also been claimed, but whether such kudurrus really represented constellations and astronomical information aside from the use of the symbols remains unclear. Star catalogues after ''Three Stars Each'' include the '' MUL.APIN'' list named after the first Babylonian constellation ', "the Plough", which is the current Triangulum constell ...

Egyptian Astronomy
Egyptian astronomy started in prehistory, prehistoric times, in the Prehistoric Egypt, Predynastic Period. In the 5th millennium BCE, the stone circles at Nabta Playa may have made use of astronomical alignments. By the time the historical Ancient Egypt, Dynastic Period began in the 3rd millennium BCE, the 365 day period of the Egyptian calendar was already in use, and the observation of stars was important in determining the annual flooding of the Nile. The Egyptian pyramids were carefully aligned towards the pole star, and the temple of Amun, Amun-Re at Karnak was aligned on the rising of the winter solstice, midwinter Sun. Astronomy played a considerable part in fixing the dates of religious festivals and determining the hours of night, and temple astrology, astrologers were especially adept at watching the stars and observing the conjunction (astronomy), conjunctions and risings of the Sun, Moon, and planets, as well as the lunar phases. In Ptolemaic Kingdom, Ptolemaic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nebra Sky Disk
The Nebra sky disc (, ) is a bronze disc of around diameter and a weight of , having a blue-green patina and inlaid with gold symbols. These symbols are interpreted generally as the Sun or full moon, a lunar crescent, and stars, including a cluster of seven stars, axiomatically interpreted as the Pleiades. Two golden arcs that were along the sides are thought to mark the angle between the solstices, one now is missing. Another arc at the bottom with internal parallel lines is usually interpreted as a solar boat with numerous oars, although some authors have also suggested that it may represent a rainbow, the Aurora Borealis, a comet, or a sickle. In 1999, the disc was found buried on the Mittelberg hill near Nebra in Germany. It is dated by archaeologists to and attributed to the Early Bronze Age Únětice culture. Various scientific analyses of the disc, the items found with the disc, and the find spot have confirmed the Early Bronze Age dating. The Nebra sky disc featu ...

Indian People
Indian people or Indians are the Indian nationality law, citizens and nationals of the India, Republic of India or people who trace their ancestry to India. While the demonym "Indian" applies to people originating from the present-day India, it was also used as the identifying term for people originating from what is now Bangladeshi diaspora, Bangladesh and Pakistani diaspora, Pakistan prior to the Partition of India in 1947. In 2022, the population of India stood at 1.4 billion people, of various Indian ethnic groups, ethnic groups. According to United Nations forecasts, India overtook China as the world's List of countries and dependencies by population, most populous country by the end of April 2023, containing 17.50 percent of the global population. In addition to the Indian population, the Non-resident Indian and Overseas Citizen of India, Indian overseas diaspora also boasts large numbers, particularly in former British Empire, British colonies due to the historical ...

Taurus (constellation)
Taurus (Latin, 'Bull') is one of the constellations of the zodiac and is located in the northern celestial hemisphere. Taurus is a large and prominent constellation in the Northern Hemisphere's winter sky. It is one of the oldest constellations, dating back to the Early Bronze Age at least, when it marked the location of the Sun during the spring equinox. Its importance to the agricultural calendar influenced sacred bull, various bull figures in the mythologies of Ancient Sumerian religion, Sumer, Akkadian religion, Akkad, Assyrian religion, Assyria, Babylonian religion, Babylon, Ancient Egyptian religion, Egypt, Ancient Greek religion, Greece, and Religion in ancient Rome, Rome. Its old astronomical symbol is (♉︎), which resembles a bull's head. A number of features exist that are of interest to astronomers. Taurus hosts two of the nearest open clusters to Earth, the Pleiades and the Hyades (star cluster), Hyades, both of which are visible to the naked eye. At first magnitu ...

French Language
French ( or ) is a Romance languages, Romance language of the Indo-European languages, Indo-European family. Like all other Romance languages, it descended from the Vulgar Latin of the Roman Empire. French evolved from Northern Old Gallo-Romance, a descendant of the Latin spoken in Northern Gaul. Its closest relatives are the other langues d'oïl—languages historically spoken in northern France and in southern Belgium, which French (Francien language, Francien) largely supplanted. It was also substratum (linguistics), influenced by native Celtic languages of Northern Roman Gaul and by the Germanic languages, Germanic Frankish language of the post-Roman Franks, Frankish invaders. As a result of French and Belgian colonialism from the 16th century onward, it was introduced to new territories in the Americas, Africa, and Asia, and numerous French-based creole languages, most notably Haitian Creole, were established. A French-speaking person or nation may be referred to as Fra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Of El Castillo
The Cueva del Castillo contains both a decorated cave and an archaeological site, within the complex of the Caves of Monte Castillo, in Puente Viesgo, Cantabria, Spain. The archaeological stratigraphy has been divided into around 19 layers, depending on the source they slightly deviate from each other, however the overall sequence is consistent, beginning in the Proto-Aurignacian, and ending in the Bronze Age. El Castillo was discovered in 1903 by Hermilio Alcalde del Río, a Spanish archaeologist, who was one of the pioneers in the study of the earliest cave paintings of Cantabria. The entrance to the cave was smaller in the past and has been enlarged as a result of archaeological excavations. Alcalde del Río found an extensive sequence of images executed in charcoal and red ochre on the walls and ceilings of multiple caverns.. The authors of the first monograph (H. Alcalde del Rio, H. Breuil, L. Sierra, ''Les cavernes de la région cantabrique (Espagne)'', Monaco, 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northern Crown
Corona Borealis is a small constellation in the Northern Celestial Hemisphere. It is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Its brightest stars form a semicircular arc. Its Latin name, inspired by its shape, means "northern crown". In classical mythology Corona Borealis generally represented the crown given by the god Dionysus to the Cretan princess Ariadne and set by her in the heavens. Other cultures likened the pattern to a circle of elders, an eagle's nest, a bear's den or a smokehole. Ptolemy also listed a southern counterpart, Corona Australis, with a similar pattern. The brightest star is the apparent magnitude, magnitude 2.2 Alpha Coronae Borealis. The yellow supergiant R Coronae Borealis is the prototype of a rare class of giant stars—the R Coronae Borealis variables—that are extremely hydrogen deficient, and thought to result from the merger of two white dwarfs.
