Jordanus (constellation)
Jordanus (the '' Jordan River'') was a constellation introduced in 1612 (or 1613) on a globe by Petrus Plancius and first shown in print by Jakob Bartsch in his book ''Usus Astronomicus Planisphaerii Stellati'' (1624). One end lay in the present-day Canes Venatici and then it flowed through the areas now occupied by Leo Minor and Lynx, ending near Camelopardalis. This constellation was not adopted in the atlases of Johann Bode and fell into disuse.

Jordan River
The Jordan River or River Jordan ( ar, نَهْر الْأُرْدُنّ, ''Nahr al-ʾUrdunn'', he, נְהַר הַיַּרְדֵּן, ''Nəhar hayYardēn''; syc, ܢܗܪܐ ܕܝܘܪܕܢܢ ''Nahrāʾ Yurdnan''), also known as ''Nahr Al-Sharieat'' ( ar, نهر الشريعة), is a river in the Middle East that flows roughly north to south through the Sea of Galilee (Hebrew: כנרת Kinneret, Arabic: Bohayrat Tabaraya, meaning Lake of Tiberias) and on to the Dead Sea. Jordan and the Golan Heights border the river to the east, while the West Bank and Israel lie to its west. Both Jordan and the West Bank take their names from the river. The river holds major significance in Judaism and Christianity. According to the Bible, the Israelites crossed it into the Promised Land and Jesus of Nazareth was baptized by John the Baptist in it. Geography The Jordan River has an upper course from its sources to the Sea of Galilee (via the Bethsaida Valley), and a lower course south of ...

Dutch Celestial Cartography In The Age Of Discovery
The history of cartography refers to the development and consequences of cartography, or mapmaking technology, throughout human history. Maps have been one of the most important human inventions for millennia, allowing humans to explain and navigate their way through the world. When and how the earliest maps were made are unknown, but maps of local terrain are believed to have been independently invented by many cultures. The earliest surviving maps include cave paintings and etchings on tusk and stone. Maps were produced extensively by ancient Babylon, Greece, Rome, China, and India. The earliest maps ignored the curvature of Earth's surface, both because the shape of the Earth was uncertain and because the curvature is not important across the small areas being mapped. However, since the age of Classical Greece, maps of large regions, and especially of the world, have used projection from a model globe in order to control how the inevitable distortion gets apportioned on the ...

Astronomy In The Dutch Republic
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowadays, professional a ...

Constellations Listed By Petrus Plancius
A constellation is an area on the celestial sphere in which a group of visible stars forms a perceived pattern or outline, typically representing an animal, mythological subject, or inanimate object. The origins of the earliest constellations likely go back to prehistory. People used them to relate stories of their beliefs, experiences, creation, or mythology. Different cultures and countries adopted their own constellations, some of which lasted into the early 20th century before today's constellations were internationally recognized. The recognition of constellations has changed significantly over time. Many changed in size or shape. Some became popular, only to drop into obscurity. Some were limited to a single culture or nation. The 48 traditional Western constellations are Greek. They are given in Aratus' work ''Phenomena'' and Ptolemy's ''Almagest'', though their origin probably predates these works by several centuries. Constellations in the far southern sky were added ...

Former Constellations
Former constellations are old historical Western constellations that for various reasons are no longer widely recognised or are not officially recognised by the International Astronomical Union (IAU). Prior to 1930, many of these defunct constellations were traditional in one or more countries or cultures. Some only lasted decades but others were referred to over many centuries. All are now recognised only for having classical or historical value. Many former constellations had complex Latinised names after objects, people, or mythological or zoological creatures. Others with unwieldy names were shortened for convenience. For example, Scutum Sobiescianum was reduced to Scutum, Mons Mensae to Mensa, and Apparatus Sculptoris to Sculptor. Some of the Northern Sky's former constellations were placed in the less populated regions between the traditional brighter constellations just to fill gaps. In the Southern Sky, new constellations were often created from about the 15th century ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydra (constellation)
Hydra is the largest of the 88 modern constellations, measuring 1303 square degrees, and also the longest at over 100 degrees. Its southern end borders Libra and Centaurus and its northern end borders Cancer. It was included among the 48 constellations listed by the 2nd century astronomer Ptolemy. Commonly represented as a water snake, it straddles the celestial equator. History and mythology Western mythology The Greek constellation of Hydra is an adaptation of a Babylonian constellation: the MUL.APIN includes a "serpent" constellation (MUL.DINGIR.MUŠ) that loosely corresponds to Hydra. It is one of two Babylonian "serpent" constellations (the other being the origin of the Greek Serpens), a mythological hybrid of serpent, lion and bird. The shape of Hydra resembles a twisting snake, and features as such in some Greek myths. One myth associates it with a water snake that a crow served Apollo in a cup when it was sent to fetch water; Apollo saw through the fraud, and angr ...

Julius Schiller
Julius Schiller (c. 1580 – 1627) was a lawyer from Augsburg, who like his fellow citizen and colleague Johann Bayer published a star atlas in celestial cartography. In the year of his death, Schiller, with Bayer's assistance, published the star atlas '' Coelum Stellatum Christianum'' which replaced the pagan names of constellations with biblical and early Christian figures. Specifically, Schiller replaced the zodiacal constellations with the twelve apostles, the northern constellations by figures from the New Testament and the southern constellations by figures from the Old Testament. The planets, sun and moon were also replaced by biblical figures. Lucas Kilian was the artist who engraved the plates. The star atlas was considered merely a curiosity and, in contrast to Bayer's ''Uranometria'', did not gain wide acceptance. ''Harmonia Macrocosmica'' by Andreas Cellarius (1660) included star maps for Schiller's constellations after the pagan ones. External links *Schill ...

Coelum Stellatum Christianum
The coelom (or celom) is the main body cavity in most animals and is positioned inside the body to surround and contain the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as molluscs, it remains undifferentiated. In the past, and for practical purposes, coelom characteristics have been used to classify bilaterian animal phyla into informal groups. Etymology The term ''coelom'' derives from the Ancient Greek word (), meaning 'cavity'. Structure Development The coelom is the mesodermally lined cavity between the gut and the outer body wall. During the development of the embryo, coelom formation begins in the gastrulation stage. The developing digestive tube of an embryo forms as a blind pouch called the archenteron. In Protostomes, the coelom forms by a process known as schizocoely. The archenteron initially forms, and the mesoderm splits into two layers: the first attaches to the body wall or ectoderm, forming th ...

Johann Bode
Johann Elert Bode (; 19 January 1747 – 23 November 1826) was a German astronomer known for his reformulation and popularisation of the Titius–Bode law. Bode determined the orbit of Uranus and suggested the planet's name. Life and career Bode was born in Hamburg. As a youth, he suffered from a serious eye disease that particularly damaged his right eye; he continued to have trouble with his eyes throughout his life. His early promise in mathematics brought him to the attention of Johann Georg Büsch, who allowed Bode to use his own library for study. He began his career with the publication of a short work on the solar eclipse of 5 August 1766. This was followed by an elementary treatise on astronomy entitled ''Anleitung zur Kenntniss des gestirnten Himmels'' (1768, 10th ed. 1844), the success of which led to his being invited to Berlin by Johann Heinrich Lambert in 1772 for the purpose of computing ephemerides on an improved plan. There he founded, in 1774, the well-known ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Camelopardalis
Camelopardalis is a large but faint constellation of the northern sky representing a giraffe. The constellation was introduced in 1612 or 1613 by Petrus Plancius. Some older astronomy books give Camelopardalus or Camelopardus as alternative forms of the name, but the version recognized by the International Astronomical Union matches the genitive form, seen suffixed to most of its key stars. Etymology First attested in English in 1785, the word ''camelopardalis'' comes from Latin, and it is the romanization of the Greek "καμηλοπάρδαλις" meaning "giraffe", from "κάμηλος" (''kamēlos''), "camel" + "πάρδαλις" (''pardalis''), " spotted", because it has a long neck like a camel and spots. Features Stars Although Camelopardalis is the 18th largest constellation, it is not a particularly bright constellation, as the brightest stars are only of fourth magnitude. In fact, it only contains four stars brighter than magnitude 5.0. * α Cam is a blue-hued su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
