Yebes
Yebes is a municipality located in the Guadalajara (province), province of Guadalajara, Castilla–La Mancha, Spain. According to the 2004 census (Instituto Nacional de Estadística (Spain), INE), the municipality had a population of 235 inhabitants. The Yebes Observatory with its Yebes Observatory RT40m, RT40m radio telescope is located in Yebes. Ciudad Valdeluz A new town called Ciudad Valdeluz is being developed within the boundaries of Yebes some 10 kilometres from the village. The project was intended to take advantage of the new high-speed railway between Madrid and Barcelona, but it has been adversely affected by the Spanish property bubble. The project to make the new town was approved in September 2002 by the provincial planning commission. The construction began in 2004 for a time estimated to complete in 7 years more and the first residents arrived in 2006. The developer Construcciones Reyal S.A. had invested more than 1.1 billion of Euros in the construction of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Instituto Geográfico Nacional (Spain)
The ''Instituto Geográfico Nacional'' (''IGN''), or National Geographic Institute is a Spanish government agency, dependent on the Spanish Ministry of Public Works. It is the national mapping agency for Spain, together with the Centro Nacional de Información Geográfica (CNIG). Since 2015, most of its products (including ''MTN50'' and ''MTN25'' topographic maps, and ''PNOA'' aerial photographies) are freely available online, and licensed under a CC-BY-4.0-like license, as ''FOM/2807/2015'' decree requires its products must be released under a free license. Roles The IGN is responsible for: # Astronomic observations and research # Observation and maintenance of the national geodetic networks # Making and updating the cartography for the country (including official National Topographic Maps, called MTN50 (1:50,000 scale) and MTN25 (1:25,000 scale)) # Making and maintaining the IDEE or Infraestructura de Datos Espaciales de España, the Spanish Spatial Data Infrastructure # ...

Radio Telescope
A radio telescope is a specialized antenna and radio receiver used to detect radio waves from astronomical radio sources in the sky. Radio telescopes are the main observing instrument used in radio astronomy, which studies the radio frequency portion of the electromagnetic spectrum emitted by astronomical objects, just as optical telescopes are the main observing instrument used in traditional optical astronomy which studies the light wave portion of the spectrum coming from astronomical objects. Unlike optical telescopes, radio telescopes can be used in the daytime as well as at night. Since astronomical radio sources such as planets, stars, nebulas and galaxies are very far away, the radio waves coming from them are extremely weak, so radio telescopes require very large antennas to collect enough radio energy to study them, and extremely sensitive receiving equipment. Radio telescopes are typically large parabolic ("dish") antennas similar to those employed in tracking an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Solar Tower (astronomy)
A solar tower, in the context of astronomy, is a structure used to support equipment for studying the Sun, and is typically part of solar telescope designs. Generically, the term solar tower has many more uses especially for a type of power production using Earth's Sun. Solar tower observatories are also called vacuum tower telescopes. Solar towers are used to raise the observation equipment above atmospheric turbulence caused by solar heating of the ground and the radiation of the heat into the atmosphere. Traditional observatories do not have to be placed high above ground level, as they do most of their observation at night, when ground radiation is at a minimum. The horizontal Snow solar observatory was built on Mount Wilson in 1904. It was soon found that heat radiation was disrupting observations. Almost as soon as the Snow Observatory opened, plans were started for a tower that opened in 1908 followed by a tower in 1912. The tower is currently used to study helio ...

Astrograph
An astrograph (or astrographic camera) is a telescope designed for the sole purpose of astrophotography. Astrographs are mostly used in wide-field astronomical surveys of the sky and for detection of objects such as asteroids, meteors, and comets. Improvements in photography in the middle 19th century led to designs dedicated to astrophotography, and they were also popular in the 20th century. As in other photography, chemicals were used that respond to light, recorded on a glass photographic plate or sometimes on photographic film. Many observatories of this period used an astrograph, beside instruments like the transit telescope, great refractors, and chronometers, or instruments for observing the Sun. Astrographs were often used to make surveys of the night sky, and one of the famous projects was Carte du Ciel. Discoveries using an astrograph include then-planet Pluto. Rather than looking through the telescope, it was discovered by using a blink comparator with im ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gravimeter
Gravimetry is the measurement of the strength of a gravitational field. Gravimetry may be used when either the magnitude of a gravitational field or the properties of matter responsible for its creation are of interest. Units of measurement Gravity is usually measured in units of acceleration. In the SI system of units, the standard unit of acceleration is 1 metre per second squared (abbreviated as m/s2). Other units include the cgs gal (sometimes known as a ''galileo'', in either case with symbol Gal), which equals 1 centimetre per second squared, and the '' g'' (''g''n), equal to 9.80665 m/s2. The value of the ''g''n is defined approximately equal to the acceleration due to gravity at the Earth's surface (although the value of ''g'' varies by location). Gravimeters An instrument used to measure gravity is known as a gravimeter. For a small body, general relativity predicts gravitational effects indistinguishable from the effects of acceleration by the equivalence pri ...

Yebes Observatory RT40m
The Yebes Observatory RT40m, or ARIESXXI, is a radio telescope which is part of the observatory at Yebes, Spain. It is a 40-metre Cassegrain–Nasmyth telescope. Location The telescope is located at Yebes Observatory (Spanish: ''Centro Astronómico de Yebes (CAY)''). Yebes Observatory is the main scientific and technical facility of the National Geographic Institute of Spain. The observatory is located around to the North-East of Madrid in the province of Guadalajara in the autonomous community of Castilla-La Mancha. It is located at an altitude of 931 meters above sea level and benefits from exceptional observing conditions throughout the year. The precipitable water vapor (PWV) level remains below 6 mm, dropping to a minimum of 2 mm during winter. The wind velocity is generally below 5 m/s for most of the year, and the occurrence of rainy or snowy days is less than one week annually. The Technological Development Centre (CDT) facilities include two radio telescopes, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Observatories In Spain
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, p ...
