Archaeoastronomy (also spelled archeoastronomy) is the study of how people in the past "have understood the phenomena in the sky, how they used these phenomena and what role the sky played in their cultures."[1] Clive Ruggles argues it is misleading to consider archaeoastronomy to be the study of ancient astronomy, as modern astronomy is a scientific discipline, while archaeoastronomy considers symbolically rich cultural interpretations of phenomena in the sky by other cultures.[2][3] It is often twinned with ethnoastronomy, the anthropological study of skywatching in contemporary societies. Archaeoastronomy is also closely associated with historical astronomy, the use of historical records of heavenly events to answer astronomical problems and the history of astronomy, which uses written records to evaluate past astronomical practice. Archaeoastronomy can be applied to all cultures and all time periods. History of archaeoastronomy[edit] ... Methodology[edit] Green archaeoastronomy[edit] Related: and pages

The Narmer Plate and the Twelve Ages of the Zodiac A new Hu for a new Zodiacal Season: Hu was resurrected in the guise of Leo. It made sense at the time but down through the millennia it was to cause utter confusion for later generations, as the original Secret of Hu became lost. (See Part 2) The Sphinx at Giza was no longer considered to be the earthly representation of Hu, God the Creator, the Celestial Sphinx. Rather, the Sphinx at Giza came to represent the Constellation of Leo, the substituted deity. Hu: Giver of Life in the Beginning.This title was usurped by Osiris. In the hieroglyphs for Hu's title "Giver of Life in the Beginning" the Lion, the Hemisphere, and the Pillar denote "the Beginning". Thoth: the Keeper of the Secrets However the Secrets of the arts, sciences, astronomy and hieroglyphics were not for the commoner to know about or understand because these were considered to be the ultimate Sacred Subjects, whose Sacred Secrets were fit only for the ears of the elite in remote Ancient Egypt.

Micro-g environment The term micro-g environment (also µg, often referred to by the term microgravity) is more or less a synonym of weightlessness and zero-G, but indicates that g-forces are not quite zero, just very small.[1] The symbol for microgravity, µg, was used on the insignias of Space Shuttle flights STS-87 and STS-107, because these flights were devoted to microgravity research in Low Earth orbit. Absence of gravity[edit] A "stationary" micro-g environment[2] would require travelling far enough into deep space so as to reduce the effect of gravity by attenuation to almost zero. This is the simplest in conception, but requires traveling an enormous distance, rendering it most impractical. From stationarity the gravity from "the rest of the Milky Way" would cause a free fall, covering a distance of 100 pm in one second, 360 nm in one minute, 1.3 mm in one hour, 70 cm in one day, 37 m in one week, 100 km in one year, and 10,000 km in 10 years (at a speed at that last location of 6 cm/s).

The Megalithic Portal and Megalith Map: Lacam de Peyrarines Ston Site Name: Lacam de Peyrarines Country: France Département: Languedoc:Gard (30) Type: Stone CircleNearest Town: Le Vigan Nearest Village: BlandasLatitude: 43.926100N Longitude: 3.530700ECondition: 5 Ambience: 5 Access: 4 Accuracy: 5 Internal Links: External Links: Lacam de Peyrarines submitted by ocdolmen It seems to be a generally held opinion that there are no "real, proper" stone circles outside the British Isles. Yet on the Causse de Blandas, in southern France, there are several, some of which are superb. The circle is about 120 metres in diameter, with still about 50 stones up to 1.8 metres tall standing in position, and has a large central menhir, standing well over 2 metres high. The stones which make up the circle are all different shapes and sizes. It is a truly wonderful place, and hardly known by anyone. IMPORTANT NOTE: Positional co-ordinates taken from a gps receiver.

Observational astronomy Galileo Galilei turned a telescope to the heavens and recorded what he saw. Since that time, observational astronomy has made steady advances with each improvement in telescope technology. A traditional division of observational astronomy is given by the region of the electromagnetic spectrum observed: Optical astronomy is the part of astronomy that uses optical components (mirrors, lenses and solid-state detectors) to observe light from near infrared to near ultraviolet wavelengths. Visible-light astronomy (using wavelengths that can be detected with the eyes, about 400 - 700 nm) falls in the middle of this range.Infrared astronomy deals with the detection and analysis of infrared radiation (this typically refers to wavelengths longer than the detection limit of silicon solid-state detectors, about 1 μm wavelength). The most common tool is the reflecting telescope but with a detector sensitive to infrared wavelengths. Sunset over Mauna Kea Observatories. Other instruments[edit]

Cham des Bondons menhir.jpg - Wikipedia, the free encyclope Planetary science Planetary science (rarely planetology) is the scientific study of planets (including Earth), moons, and planetary systems, in particular those of the Solar System and the processes that form them. It studies objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, interrelations and history. It is a strongly interdisciplinary field, originally growing from astronomy and earth science,[1] but which now incorporates many disciplines, including planetary astronomy, planetary geology (together with geochemistry and geophysics), atmospheric science, oceanography, hydrology, theoretical planetary science, glaciology, and exoplanetology.[1] Allied disciplines include space physics, when concerned with the effects of the Sun on the bodies of the Solar System, and astrobiology. There are interrelated observational and theoretical branches of planetary science. History[edit] Disciplines[edit] Planetary astronomy[edit] Geomorphology[edit]

La Cham des Bondons Un article de Wikipédia, l'encyclopédie libre. Avec ses 154 menhirs de granit, le site constitue la deuxième concentration de monuments mégalithiques en Europe après les alignements de Carnac en Bretagne. On estime que la mise en place de ces pierres doit se situer entre la fin du Néolithique et l'âge du bronze. Le site de la Cham des Bondons fait partie du parc national des Cévennes. Le site archéologique de la Cham des Bondons[modifier | modifier le code] Deux menhirs en premier plan, l'un des puechs à l'arrière Ce site est unique dans tout le sud de la France. Le premier grand inventaire de ces monolithes remonte aux années 1940 avec le docteur Morel qui en dresse deux inventaires. Parmi ces derniers, on notera au sud des hameaux de la Vaissière et de la Fare deux très grands menhirs mesurant respectivement 4,80 m et 4,50 m hors sol.

Astrometry Illustration of the use of interferometry in the optical wavelength range to determine precise positions of stars. Courtesy NASA/JPL-Caltech Astrometry is the branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. The information obtained by astrometric measurements provides information on the kinematics and physical origin of our Solar System and our galaxy, the Milky Way. History[edit] The history of astrometry is linked to the history of star catalogues, which gave astronomers reference points for objects in the sky so they could track their movements. In the 10th century, Abd al-Rahman al-Sufi carried out observations on the stars and described their positions, magnitudes and star color, and gave drawings for each constellation, in his Book of Fixed Stars. James Bradley first tried to measure stellar parallaxes in 1729. Applications[edit] Astronomers use astrometric techniques for the tracking of near-Earth objects.
