Lunar Eclipse
A lunar eclipse occurs when the Moon moves into the Earth's shadow. Such alignment occurs during an eclipse season, approximately every six months, during the full moon phase, when the Moon's orbital plane is closest to the plane of the Earth's orbit. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy) with Earth between the other two, which can happen only on the night of a full moon when the Moon is near either lunar node. The type and length of a lunar eclipse depend on the Moon's proximity to the lunar node. When the moon is totally eclipsed by the Earth, it takes on a reddish color that is caused by the planet when it completely blocks direct sunlight from reaching the Moon surface, as only the light reflected from the lunar surface has been refracted by Earth's atmosphere. This light appears reddish due to the Rayleigh scattering of blue light, the same reason sunrise and sunsets are more orange than during the day. Un ...

Saros Cycle
The saros () is a period of exactly 223 synodic months, approximately 6585.3211 days, or 18 years, 10, 11, or 12 days (depending on the number of leap years), and 8 hours, that can be used to predict eclipses of the Sun and Moon. One saros period after an eclipse, the Sun, Earth, and Moon return to approximately the same relative geometry, a near straight line, and a nearly identical eclipse will occur, in what is referred to as an eclipse cycle. A sar is one half of a saros. A series of eclipses that are separated by one saros is called a ''saros series''. It corresponds to: *6,585.321347 solar days *18.029 years *223 synodic months *241.999 draconic months *18.999 eclipse years (38 eclipse seasons) *238.992 anomalistic months The 19 eclipse years means that if there is a solar eclipse (or lunar eclipse), then after one saros a new moon will take place at the same node of the orbit of the Moon, and under these circumstances another eclipse can occur.

Iptar-Sin
Iptar-Sin or IB.TAR.SînmIB.TAR-d30. (reading uncertain), was the 51st Assyrian king according to the ''Assyrian King List''.''Ḫorsābād King List'' ii 18. He reigned for 12 years some time during the 17th century BC. Biography The ''Assyrian King List'' provides a sequence of five kings with short reigns purported to be father-son successions, leading Landsberger to suggest that Libaya, Sharma-Adad I and Iptar-Sin may have been brothers of Belu-bani rather than his descendants. The list reports Iptar-Sin as the son of Sharma-Adad I. He is omitted from the list on another fragment.KAV 14.

King Of Assyria
The king of Assyria (Akkadian: ''Išši'ak Aššur'', later ''šar māt Aššur'') was the ruler of the ancient Mesopotamian kingdom of Assyria, which was founded in the late 21st century BC and fell in the late 7th century BC. For much of its early history, Assyria was little more than a city-state, centered on the city Assur, but from the 14th century BC onwards, Assyria rose under a series of warrior kings to become one of the major political powers of the Ancient Near East, and in its last few centuries it dominated the region as the largest empire the world had seen thus far. Ancient Assyrian history is typically divided into the Old, Middle and Neo-Assyrian periods, all marked by ages of ascendancy and decline. The ancient Assyrians did not believe that their king was divine himself, but saw their ruler as the vicar of their principal deity, Ashur, and as his chief representative on Earth. In their worldview, Assyria represented a place of order while lands not governed by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arpachshad
Arpachshad ( he, אַרְפַּכְשַׁד – ''ʾArpaḵšaḏ'', in pausa – ''ʾArpaḵšāḏ''; gr, Ἀρφαξάδ – ''Arphaxád''), alternatively spelled Arphaxad or Arphacsad, is one of the postdiluvian men in the ShemTerah genealogy. The name is recorded in the Book of Genesis in the Hebrew Bible (or Old Testament of Christian Bible) and subsequently copied in different biblical books, including the Gospel of Luke in the New Testament. Biblical accounts According to the Book of Genesis he was one of the five sons of Shem (the son of Noah). He is the twelfth name of the Genesis genealogy that traces Abrahams ancestry from Adam to Terah (cf. ). Beginning with Adam, nine Antediluvian names are given that predate Noah and the Flood, and nine postdiluvian, beginning with Noah's eldest son Shem and ending with Terah. According to the text, Arpachshad's brothers were Elam, Asshur, Lud and Aram. Arpachshad's son is called Selah, except in the Septuagint, whe ...

Shem
Shem (; he, שֵׁם ''Šēm''; ar, سَام, Sām) ''Sḗm''; Ge'ez: ሴም, ''Sēm'' was one of the sons of Noah in the book of Genesis and in the book of Chronicles, and the Quran. The children of Shem were Elam, Ashur, Arphaxad, Lud and Aram, in addition to unnamed daughters. Abraham, the patriarch of Jews, Christians, and Muslims, was one of the descendants of Arphaxad. Islamic literature describes Shem as one of the believing sons of Noah. Some sources even identify Shem as a prophet in his own right and that he was the next prophet after his father. Shem is mentioned several times in Genesis 5-11 as well as 1 Chronicles 1:4. In the Bible Genesis 10 Genesis 10:21 refers to relative ages of Shem and his brother Japheth, but with sufficient ambiguity to have yielded different English translations. The verse is translated in the King James Version as: "Unto Shem also, the father of all the children of Eber, the brother of Japheth the elder, even to him wer ...

Hebrew Calendar
The Hebrew calendar ( he, הַלּוּחַ הָעִבְרִי, translit=HaLuah HaIvri), also called the Jewish calendar, is a lunisolar calendar used today for Jewish religious observance, and as an official calendar of the state of Israel. It determines the dates for Jewish holidays and the appropriate Torah reading, public reading of Weekly Torah portion, Torah portions, ''yahrzeits'' (dates to commemorate the death of a relative), and daily Psalm readings, among many ceremonial uses. In Israel, it is used for religious purposes, provides a time frame for agriculture, and is an official calendar for civil holidays, alongside the Gregorian calendar. The present Hebrew calendar is the result of a process of development, including a Babylonian calendar, Babylonian influence. Until the Tannaitic period (approximately 10–220 Common Era, CE), the calendar employed a new lunar phase, crescent moon, with an Intercalation (timekeeping), additional month normally added every two or ...

Saturn
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine and a half times that of Earth. It has only one-eighth the average density of Earth; however, with its larger volume, Saturn is over 95 times more massive. Saturn's interior is most likely composed of a core of iron–nickel and rock (silicon and oxygen compounds). Its core is surrounded by a deep layer of metallic hydrogen, an intermediate layer of liquid hydrogen and liquid helium, and finally, a gaseous outer layer. Saturn has a pale yellow hue due to ammonia crystals in its upper atmosphere. An electrical current within the metallic hydrogen layer is thought to give rise to Saturn's planetary magnetic field, which is weaker than Earth's, but which has a magnetic moment 580 times that of Earth due to Saturn's larger size. Saturn's magnetic field strength is around one-twentieth of Jupiter's. The outer atmosphere is g ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2060 Chiron
2060 Chiron is a small Solar System body in the outer Solar System, orbiting the Sun between Saturn and Uranus. Discovered in 1977 by Charles Kowal, it was the first-identified member of a new class of objects now known as centaurs—bodies orbiting between the asteroid belt and the Kuiper belt.944 Hidalgo, discovered in 1920, also fits this definition, but was not identified as belonging to a distinct population. Although it was initially called an asteroid and classified only as a minor planet with the designation "2060 Chiron", in 1989 it was found to exhibit behavior typical of a comet. Today it is classified as both a minor planet and a comet, and is accordingly also known by the cometary designation 95P/Chiron. Chiron is named after the centaur Chiron in Greek mythology. History Discovery Chiron was discovered on 1 November 1977 by Charles Kowal from images taken on 18 October at Palomar Observatory. It was given the temporary designation of . It was found near aphe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
