Star Catalog
A star catalogue is an astronomical catalogue that lists stars. In astronomy, many stars are referred to simply by catalogue numbers. There are a great many different star catalogues which have been produced for different purposes over the years, and this article covers only some of the more frequently quoted ones. Star catalogues were compiled by many different ancient people, including the Babylonians, Greeks, Chinese, Persians, and Arabs. They were sometimes accompanied by a star chart for illustration. Most modern catalogues are available in electronic format and can be freely downloaded from space agencies' data centres. The largest is being compiled from the spacecraft Gaia and thus far has over a billion stars. Completeness and accuracy are described by the faintest limiting magnitude V (largest number) and the accuracy of the positions.

Perseus Hevelius 2
In Greek mythology, Perseus ( /ˈpɜːrsiəs, -sjuːs/; Greek: Περσεύς, translit. Perseús) is the legendary founder of Mycenae and of the Perseid dynasty. He was, alongside Cadmus and Bellerophon, the greatest Greek hero and slayer of monsters before the days of Heracles. He beheaded the Gorgon Medusa for Polydectes and saved Andromeda from the sea monster Cetus. He was the son of Zeus and the mortal Danaë, as well as the half-brother and great-grandfather of Heracles (as they were both children of Zeus, and Heracles' mother was descended from Perseus). Etymology Because of the obscurity of the name "Perseus" and the legendary character of its bearer, most etymologists presume that it might be pre-Greek; however, the name of Perseus's native city was Greek and so were the names of his wife and relatives. There is some idea that it descended into Greek from the Proto-Indo-European language. In that regard Robert Graves has proposed the only Greek derivation avai ...

Star Clock
A star is an astronomical object comprising a luminous spheroid of plasma held together by its gravity. The nearest star to Earth is the Sun. Many other stars are visible to the naked eye at night, but their immense distances from Earth make them appear as fixed points of light. The most prominent stars have been categorised into constellations and asterisms, and many of the brightest stars have proper names. Astronomers have assembled star catalogues that identify the known stars and provide standardized stellar designations. The observable universe contains an estimated to stars. Only about 4,000 of these stars are visible to the naked eye, all within the Milky Way galaxy. A star's life begins with the gravitational collapse of a gaseous nebula of material composed primarily of hydrogen, along with helium and trace amounts of heavier elements. Its total mass is the main factor determining its evolution and eventual fate. A star shines for most of its active life d ...

Neo-Babylonian Empire
The Neo-Babylonian Empire or Second Babylonian Empire, historically known as the Chaldean Empire, was the last polity ruled by monarchs native to Mesopotamia. Beginning with the coronation of Nabopolassar as the King of Babylon in 626 BC and being firmly established through the fall of the Neo-Assyrian Empire in 612 BC, the Neo-Babylonian Empire was conquered by the Achaemenid Persian Empire in 539 BC, marking the collapse of the Chaldean dynasty less than a century after its founding. The defeat of the Neo-Assyrian Empire and subsequent transfer of power to Babylon marked the first time that the city, and southern Mesopotamia in general, had risen to dominate the ancient Near East since the collapse of the Old Babylonian Empire (under Hammurabi) nearly a thousand years earlier. The period of Neo-Babylonian rule thus saw unprecedented economic and population growth throughout Babylonia, as well as a renaissance of culture and artwork as Neo-Babylonian kings conducted mass ...

Enlil
Enlil, , "Lord f theWind" later known as Elil, is an ancient Mesopotamian god associated with wind, air, earth, and storms. He is first attested as the chief deity of the Sumerian pantheon, but he was later worshipped by the Akkadians, Babylonians, Assyrians, and Hurrians. Enlil's primary center of worship was the Ekur temple in the city of Nippur, which was believed to have been built by Enlil himself and was regarded as the "mooring-rope" of heaven and earth. He is also sometimes referred to in Sumerian texts as Nunamnir. According to one Sumerian hymn, Enlil himself was so holy that not even the other gods could look upon him. Enlil rose to prominence during the twenty-fourth century BC with the rise of Nippur. His cult fell into decline after Nippur was sacked by the Elamites in 1230 BC and he was eventually supplanted as the chief god of the Mesopotamian pantheon by the Babylonian national god Marduk. Enlil plays a vital role in the Sumerian creation myth; he se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Celestial Equator
The celestial equator is the great circle of the imaginary celestial sphere on the same plane as the equator of Earth. This plane of reference bases the equatorial coordinate system. In other words, the celestial equator is an abstract projection of the terrestrial equator into outer space. Due to Earth's axial tilt, the celestial equator is currently inclined by about 23.44° with respect to the ecliptic (the plane of Earth's orbit), but has varied from about 22.0° to 24.5° over the past 5 million years due to perturbation from other planets. An observer standing on Earth's equator visualizes the celestial equator as a semicircle passing through the zenith, the point directly overhead. As the observer moves north (or south), the celestial equator tilts towards the opposite horizon. The celestial equator is defined to be infinitely distant (since it is on the celestial sphere); thus, the ends of the semicircle always intersect the horizon due east and due west, re ...

Enuma Anu Enlil
Enuma Anu Enlil ( ,'' The Assyrian Dictionary'', volume 7 (I/J) – ''inūma'', The Oriental Institute, Chicago 1960, s. 160. ''When he godsAnu and Enlil'' .., abbreviated EAE, is a major series of 68 or 70 tablets (depending on the recension) dealing with Babylonian astrology. The bulk of the work is a substantial collection of omens, estimated to number between 6500 and 7000, which interpret a wide variety of celestial and atmospheric phenomena in terms relevant to the king and state. Overview Enuma Anu Enlil is the principal source of omens used in the regular astrological reports that were sent to the Neo-Assyrian king by his entourage of scholars. There are well over 500 such reports published in volume 8 of the State Archives of Assyria. A majority of these reports simply list the relevant omens that best describe recent celestial events and many add brief explanatory comments concerning the interpretation of the omens for the benefit of the king. A typical report deal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neo-Assyrian Empire
The Neo-Assyrian Empire was the fourth and penultimate stage of ancient Assyrian history and the final and greatest phase of Assyria as an independent state. Beginning with the accession of Adad-nirari II in 911 BC, the Neo-Assyrian Empire grew to dominate the ancient Near East throughout much of the 8th and 7th centuries BC, becoming the largest empire in history up to that point. Because of its geopolitical dominance and ideology based in world domination, the Neo-Assyrian Empire is by many researchers regarded to have been the first world empire in history. At its height, the empire was the strongest military power in the world and ruled over all of Mesopotamia, the Levant and Egypt, as well as portions of Anatolia, Arabia and modern-day Iran and Armenia. The early Neo-Assyrian kings were chiefly concerned with restoring Assyrian control over much of northern Mesopotamia and Syria, since significant portions of the preceding Middle Assyrian Empire had been lost during ...

Kassites
The Kassites () were people of the ancient Near East, who controlled Babylonia after the fall of the Old Babylonian Empire c. 1531 BC and until c. 1155 BC (short chronology). They gained control of Babylonia after the Hittite sack of Babylon in 1531 BC, and established a dynasty generally assumed to have been based first in that city, after a hiatus. Later rule shifted to the new city of Dur-Kurigalzu. By the time of Babylon's fall, the Kassites had already been part of the region for a century and a half, acting sometimes with the Babylon's interests and sometimes against. There are records of Kassite and Babylonian interactions, in the context of military employment, during the reigns of Babylonian kings Samsu-iluna (1686 to 1648 BC), Abī-ešuh, and Ammī-ditāna. The origin and classification of the Kassite language, like the Sumerian language and Hurrian language, is uncertain, and, also like the two latter languages, has generated a wide array of speculation over th ...

Mesopotamia
Mesopotamia ''Mesopotamíā''; ar, بِلَاد ٱلرَّافِدَيْن or ; syc, ܐܪܡ ܢܗܪ̈ܝܢ, or , ) is a historical region of Western Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. Today, Mesopotamia occupies modern Iraq. In the broader sense, the historical region included present-day Iraq and Kuwait and parts of present-day Iran, Syria and Turkey. The Sumerians and Akkadians (including Assyrians and Babylonians) originating from different areas in present-day Iraq, dominated Mesopotamia from the beginning of written history () to the fall of Babylon in 539 BC, when it was conquered by the Achaemenid Empire. It fell to Alexander the Great in 332 BC, and after his death, it became part of the Greek Seleucid Empire. Later the Arameans dominated major parts of Mesopotamia (). Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. It has be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Babylonian Astronomy
Babylonian astronomy was the study or recording of celestial objects during the early history of Mesopotamia. Babylonian astronomy seemed to have focused on a select group of stars and constellations known as Ziqpu stars. These constellations may have been collected from various earlier sources. The earliest catalogue, ''Three Stars Each'', mentions stars of the Akkadian Empire, of Amurru, of Elam and others. A numbering system based on sixty was used, a sexagesimal system. This system simplified the calculating and recording of unusually great and small numbers. The modern practices of dividing a circle into 360 degrees, of 60 minutes each, began with the Sumerians. 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.

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 ...
