Jean-Philippe Loys De Cheseaux
Jean-Philippe Loys de Cheseaux (; 4 May 1718 – 30 November 1751) was a Swiss astronomer. Biography Loys de Cheseaux was born on 4 May 1718 in Lausanne, Vaud, to Paul-Etienne Loys de Cheseaux, a banneret, and Estienne-Judith de Crousaz. His brother was Charles-Louis Loys de Cheseaux. He was educated by his maternal grandfather, the mathematician and philosopher Jean-Pierre de Crousaz, and wrote his first essays, under the title ''Essais de Physique'', in 1735, aged 17. In 1736, Loys de Cheseaux installed an observatory in his father's lands in Cheseaux-sur-Lausanne. He acquired a reputation in Europe as an astronomer with the publication of his ''Traité de la Comète'', in 1744, a treatise on his observations of the comet C/1743 X1 in which he also became one of the first to state, in its modern form, what would later be known as Olbers' paradox (that, if the universe is infinite, the night sky should be bright). After his discovery of C/1743 (along with Dirk Klinkenberg ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dirk Klinkenberg
Dirk Klinkenberg (15 November 1709, Haarlem – 3 March 1799, The Hague) was secretary of the Dutch government for 40 years. He was also known as a mathematician and amateur astronomer. Jan de Munck, Dirk Klinkenberg, and Jean-Philippe de Cheseaux each independently discovered the Great Comet of 1744 (aka C/1743 X1). Klinkenberg would later also discover comets C/1748 K1 and C/1762 K1. Asteroid 10427 Klinkenberg, named after him, was discovered on September 24, 1960 by husband and wife team Cornelis Johannes van Houten and Ingrid van Houten-Groeneveld Ingrid van Houten-Groeneveld (; 21 October 1921 – 30 March 2015) was a Dutch astronomer.

Jerusalem
Jerusalem (; he, יְרוּשָׁלַיִם ; ar, القُدس ) (combining the Biblical and common usage Arabic names); grc, Ἱερουσαλήμ/Ἰεροσόλυμα, Hierousalḗm/Hierosóluma; hy, Երուսաղեմ, Erusałēm. is a city in Western Asia. Situated on a plateau in the Judaean Mountains between the Mediterranean Sea, Mediterranean and the Dead Sea, it is one of the List of oldest continuously inhabited cities, oldest cities in the world and is considered to be a holy city for the three major Abrahamic religions: Judaism, Christianity, and Islam. Both Israelis and Palestinians claim Jerusalem as their Capital city, capital, as Israel maintains its primary governmental institutions there and the State of Palestine ultimately foresees it as its seat of power. Because of this dispute, Status of Jerusalem, neither claim is widely recognized internationally. Throughout History of Jerusalem, its long history, Jerusalem has been destroyed at least twice, Sie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Equinoxes
A solar equinox is a moment in time when the Sun crosses the Earth's equator, which is to say, appears directly above the equator, rather than north or south of the equator. On the day of the equinox, the Sun appears to rise "due east" and set "due west". This occurs twice each year, around 20 March and 23 September. More precisely, an equinox is traditionally defined as the time when the plane of Earth's equator passes through the geometric center of the Sun's disk. Equivalently, this is the moment when Earth's rotation axis is directly perpendicular to the Sun-Earth line, tilting neither toward nor away from the Sun. In modern times, since the Moon (and to a lesser extent the planets) causes Earth's orbit to vary slightly from a perfect ellipse, the equinox is officially defined by the Sun's more regular ecliptic longitude rather than by its declination. The instants of the equinoxes are currently defined to be when the apparent geocentric longitude of the Sun is 0° and 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solstices
A solstice is an event that occurs when the Sun appears to reach its most northerly or southerly excursion relative to the celestial equator on the celestial sphere. Two solstices occur annually, around June 21 and December 21. In many countries, the seasons of the year are determined by the solstices and the equinoxes. The term ''solstice'' can also be used in a broader sense, as the day when this occurs. The day of a solstice in either hemisphere has either the most sunlight of the year (summer solstice) or the least sunlight of the year (winter solstice) for any place other than the Equator. Alternative terms, with no ambiguity as to which hemisphere is the context, are "June solstice" and "December solstice", referring to the months in which they take place every year. The word ''solstice'' is derived from the Latin ''sol'' ("sun") and ''sistere'' ("to stand still"), because at the solstices, the Sun's declination appears to "stand still"; that is, the seasonal movement of ...

Book Of Daniel
The Book of Daniel is a 2nd-century BC biblical apocalypse with a 6th century BC setting. Ostensibly "an account of the activities and visions of Daniel, a noble Jew exiled at Babylon", it combines a prophecy of history with an eschatology (a portrayal of end times) both cosmic in scope and political in focus, and its message is that just as the God of Israel saves Daniel from his enemies, so he would save all Israel in their present oppression. The Hebrew Bible includes Daniel in the ''Ketuvim'' (writings), while Christian biblical canons group the work with the Major Prophets. It divides into two parts: a set of six court tales in chapters 1–6, written mostly in Aramaic, and four apocalyptic visions in chapters 7–12, written mostly in Hebrew; the deuterocanonical books contain three additional sections, the Prayer of Azariah and Song of the Three Holy Children, Susanna, and Bel and the Dragon. The book's influence has resonated through later ages, from the community of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biblical Chronology
The chronology of the Bible is an elaborate system of lifespans, 'generations', and other means by which the Masoretic Hebrew Bible (the text of the Bible most commonly in use today) measures the passage of events from the creation to around 164 BCE (the year of the re-dedication of the Second Temple). It was theological in intent, not historical in the modern sense, and functions as an implied prophecy whose key lies in the identification of the final event. The passage of time is measured initially by adding the ages of the Patriarchs at the birth of their firstborn sons, later through express statements, and later still by the synchronised reigns of the kings of Israel and Judah. The chronology is highly schematic, marking out a world cycle of 4,000 years. The Exodus takes place in the year Anno Mundi 2666, exactly two thirds of the way through the four thousand years; the construction of Solomon's Temple is commenced 480 years, or 12 generations of 40 years each, after t ...

Guillaume Bigourdan
Camille Guillaume Bigourdan (; 6 April 1851 – 28 February 1932) was a French astronomer. Personal life Bigourdan was born at Sistels, Tarn-et-Garonne to Pierre Bigourdan and Jeanne Carrière. When his teachers and local curate recognised his intelligence, he was transferred to a local boarding school in Valence d’Agen, where he excelled. In 1870, he received his Baccalauréat with mention of “Assez Bien.” He married Marie Mélanie Sophie Mouchez, the eldest daughter of Admiral Amédée Mouchez. Together, the two had 9 children. The entire family, including the Mouchez cousins, would frequently vacation in Sistels until the outbreak of the First World War, after which Bigourdan would vacation alone. During these vacations, he would farm his land and visit former classmates. He was fluent in Occitan, and spoke it when in Sistels. Academic and Scientific Career Bigourdan studied at the University of Toulouse from 1870, where he received a physics degree in 1874 and ...

Le Gentil
Guillaume Joseph Hyacinthe Jean-Baptiste Le Gentil de la Galaisière (, 12 September 1725 – 22 October 1792) was a French astronomer who discovered several nebulae and was appointed to the Royal Academy of Sciences. He made unsuccessful attempts to observe the 1761 and 1769 transits of Venus from India. Biography Guillaume Le Gentil was born in Coutances and first intended to enter the church before turning to astronomy. He discovered what are now known as the Messier objects M32, M36 and M38, as well as the nebulosity in M8, and he was the first to catalogue the dark nebula sometimes known as Le Gentil 3 (in the constellation Cygnus). He was part of the international collaborative project organized by Mikhail Lomonosov to measure the distance to the Sun, by observing the transit of Venus at different points on the earth. Edmond Halley had suggested the idea, but it required careful measurements from different places on earth, and the project was launched with more than ...
