Tonantzintla Observatory
Tonantzintla Observatory ( es, Observatorio de Tonantzintla, link=no) is an astronomical observatory located in the municipality of San Andrés Cholula in the Mexican state of Puebla. It consists of two adjacent facilities: the National Astrophysical Observatory of Tonantzintla ( es, Observatorio Astrofísico Nacional de Tonantzintla, link=no - OANTON), operated by the National Institute of Astrophysics, Optics and Electronics (INAOE), and the National Astronomical Observatory - Tonantzintla ( es, Observatorio Astronómico Nacional - Tonantzintla, link=no—OAN - Tonantzintla), operated by the National Autonomous University of Mexico (UNAM). OANTON is located on the INAOE campus, which includes numerous other buildings. OAN - Tonantzintla is located immediately to the east on mostly unused property. The observatory is located west of Puebla and east of Popocatépetl, eruptions of which sometimes interfere with observing. National Astrophysical Observatory of Tonantzintla O ...

National Institute Of Astrophysics, Optics And Electronics
The National Institute of Astrophysics, Optics and Electronics (in Spanish: ''Instituto Nacional de Astrofísica, Óptica y Electrónica, INAOE'') is a Mexican science research institute located in Tonantzintla, Puebla. Founded by presidential decree on November 12, 1971, it has over 100 researchers in Astrophysics, Optics, Electronics and Computing Science, with postgraduate programs in these areas. INAOE is one of 30 public research centers sponsored by the National Council of Science and Technology of Mexico (''CONACyT''). The Institute, in partnership with the University of Massachusetts Amherst, developed the Large Millimeter Telescope / Gran Telescopio Milimétrico on the Puebla-Veracruz border. The asteroid 14674 INAOE was named after this institute. Structure There are four departments with a number of research groups and laboratories: * Astrophysics (José Ramón Valdés Parra) ** Visible Astronomical Instrumentation Laboratory and of High Energies (Esperanza C ...

Valley Of Mexico
The Valley of Mexico ( es, Valle de México) is a highlands plateau in central Mexico roughly coterminous with present-day Mexico City and the eastern half of the State of Mexico. Surrounded by mountains and volcanoes, the Valley of Mexico was a centre for several pre-Columbian civilizations, including Teotihuacan, the Toltec, and the Aztec. The ancient Aztec term ('Land Between the Waters') and the phrase Basin of Mexico are both used at times to refer to the Valley of Mexico. The Basin of Mexico became a well known site that epitomized the scene of early Classic Mesoamerican cultural development as well. The Valley of Mexico is located in the Trans-Mexican Volcanic Belt. The valley contains most of the Greater Mexico City, Mexico City Metropolitan Area, as well as parts of the State of Mexico, Hidalgo (state), Hidalgo, Tlaxcala, and Puebla. The Basin of Mexico covers approximately in the NNE-SSW direction with length to width dimensions of approximately to The Valley of ...

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] |
Carte Du Ciel
The Carte du Ciel (literally, 'Map of the Sky') and the Astrographic Catalogue (or Astrographic Chart) were two distinct but connected components of a massive international astronomical project, initiated in the late 19th century, to catalogue and map the positions of millions of stars as faint as 11th or 12th magnitude. Twenty observatories from around the world participated in exposing and measuring more than 22,000 (glass) photographic plates in an enormous observing programme extending over several decades. Despite, or because of, its vast scale, the project was only ever partially successful – the Carte du Ciel component was never completed, and for almost half a century the Astrographic Catalogue part was largely ignored. However, the appearance of the Hipparcos Catalogue in 1997 has led to an important development in the use of this historical plate material. Origins and goals A vast and unprecedented international star-mapping project was initiated in 1887 by Pari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Wilson Observatory
The Mount Wilson Observatory (MWO) is an astronomical observatory in Los Angeles County, California, United States. The MWO is located on Mount Wilson, a peak in the San Gabriel Mountains near Pasadena, northeast of Los Angeles. The observatory contains two historically important telescopes: the Hooker telescope, which was the largest aperture telescope in the world from its completion in 1917 to 1949, and the 60-inch telescope which was the largest operational telescope in the world when it was completed in 1908. It also contains the Snow solar telescope completed in 1905, the 60 foot (18 m) solar tower completed in 1908, the 150 foot (46 m) solar tower completed in 1912, and the CHARA array, built by Georgia State University, which became fully operational in 2004 and was the largest optical interferometer in the world at its completion. Due to the inversion layer that traps warm air and smog over Los Angeles, Mount Wilson has steadier air than any other location in Nor ...
