Akari (satellite)
Akari (ASTRO-F) was an infrared astronomy satellite developed by Japan Aerospace Exploration Agency, in cooperation with institutes of Europe and Korea. It was launched on 21 February 2006, at 21:28 UTC (06:28, 22 February JST) by M-V rocket into Earth sun-synchronous orbit. After its launch it was named ''Akari'' (明かり), which means ''light'' in Japanese. Earlier on, the project was known as IRIS (InfraRed Imaging Surveyor). Its primary mission was to survey the entire sky in near-, mid- and far-infrared, through its aperture telescope. Technical design Its designed lifespan, of far- and mid-infrared sensors, was 550 days, limited by its liquid helium coolant. Its telescope mirror was made of silicon carbide to save weight. The budget for the satellite was ¥13,4 billion (~). History By mid-August 2006, Akari finished around 50 percent of the all sky survey. By early November 2006, first (phase-1) all-sky survey finished. Second (phase-2) all-sky survey started ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrodome
The NRG Astrodome, also known as the Houston Astrodome or simply the Astrodome, is the world's first multi-purpose, domed sports stadium, located in Houston, Texas. It was financed and assisted in development by Roy Hofheinz, mayor of Houston and known for pioneering modern stadiums. Construction on the stadium began in 1962, and it officially opened in 1965. It served as home to the Houston Astros of Major League Baseball (MLB) from its opening until 1999, and the home to the Houston Oilers of the National Football League (NFL) from 1968 until 1996, and also the part-time home of the Houston Rockets of the National Basketball Association (NBA) from 1971 until 1975. Additionally, the Astrodome was the primary venue of the Houston Livestock Show and Rodeo from 1966 until 2002. When opened, it was named the Harris County Domed Stadium and was nicknamed the "Eighth Wonder of the World". After the original natural grass playing surface died, the Astrodome became the first major sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astro Convention
Astro is a contract bridge bidding convention used to intervene over an opponent's one notrump (1NT) opening bid. The name is derived from the initials of the surnames of its inventors - Paul Allinger, Roger Stern and Lawrence Rosler. Astro employs a 2-level overcall in a minor suit when holds an unbalanced hand with at least nine cards in two suits, at least one of which is a major; hand strength should be unsuitable for, or not strong enough for a penalty double, typically no more than 15 points. The minor suit overcalls are artificial and carry the following meanings: :*2 shows at least 5-4 or 4-5 length in hearts and a minor suit, and :*2 shows at least 5-4 or 4-5 length in spades and another suit. When playing Astro but not holding the prescribed two-suited hand, the following calls are available over the 1NT opening by the opponents: :*an overcall of 2 or 2 is natural showing a single-suited hand :*Double is for penalties Subsequent bidding For purposes of subsequent b ...

Astropy
Astropy is a collection of software packages written in the Python programming language and designed for use in astronomy. The software is a single, free, core package for astronomical utilities due to the increasingly widespread usage of Python by astronomers, and to foster interoperability between various extant Python astronomy packages. Astropy is included in several large Python distributions; it is part of package managers for Linux and macOS, the Anaconda Python Distribution, Enthought Canopy and Ureka. Development Around the turn of the millennium the Space Telescope Science Institute (STScI) started development of Python-based utilities to extend or substitute existing astronomical data analysis tools on a modern, object-oriented platform. Among the first projects were a replacement of the command language for the Image Reduction and Analysis Facility ( IRAF) with a Python frontend, and the PyFITS interface to the Flexible Image Transport System.

Astrophysics
Astrophysics is a science that employs the methods and principles of physics and chemistry in the study of astronomical objects and phenomena. As one of the founders of the discipline said, Astrophysics "seeks to ascertain the nature of the heavenly bodies, rather than their positions or motions in space–''what'' they are, rather than ''where'' they are." Among the subjects studied are the Sun, other stars, galaxies, extrasolar planets, the interstellar medium and the cosmic microwave background. Emissions from these objects are examined across all parts of the electromagnetic spectrum, and the properties examined include luminosity, density, temperature, and chemical composition. Because astrophysics is a very broad subject, ''astrophysicists'' apply concepts and methods from many disciplines of physics, including classical mechanics, electromagnetism, statistical mechanics, thermodynamics, quantum mechanics, relativity, nuclear and particle physics, and atomic and m ...

Astrometry
Astrometry is a branch of astronomy that involves precise measurements of the positions and movements of stars and other celestial bodies. It provides the kinematics and physical origin of the Solar System and this galaxy, the Milky Way. History 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. This can be dated back to Hipparchus, who around 190 BC used the catalogue of his predecessors Timocharis and Aristillus to discover Earth's precession. In doing so, he also developed the brightness scale still in use today. Hipparchus compiled a catalogue with at least 850 stars and their positions. Hipparchus's successor, Ptolemy, included a catalogue of 1,022 stars in his work the '' Almagest'', giving their location, coordinates, and brightness. In the 10th century, Abd al-Rahman al-Sufi carried out observations on the stars and described their positions, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astro-geodetic
Geodetic astronomy or astronomical geodesy (astro-geodesy) is the application of astronomical methods into geodetic networks and other technical projects of geodesy. Applications The most important applications are: * Establishment of geodetic datum systems (e.g. ED50) or at expeditions * apparent places of stars, and their proper motions * precise astronomical navigation * astro-geodetic geoid determination * modelling the rock densities of the topography and of geological layers in the subsurface * Monitoring of the Earth rotation and polar wandering * Contribution to the time system of physics and geosciences Measuring techniques Important measuring techniques are: * Latitude determination and longitude determination, by theodolites, tacheometers, astrolabes or zenith cameras * time and star positions by observation of star transits, e.g. by meridian circles (visual, photographic or CCD) * Azimuth determination ** for the exact orientation of geodetic networks ** for ...

Astrochemistry
Astrochemistry is the study of the abundance and reactions of molecules in the Universe, and their interaction with radiation. The discipline is an overlap of astronomy and chemistry. The word "astrochemistry" may be applied to both the Solar System and the interstellar medium. The study of the abundance of elements and isotope ratios in Solar System objects, such as meteorites, is also called cosmochemistry, while the study of interstellar atoms and molecules and their interaction with radiation is sometimes called molecular astrophysics. The formation, atomic and chemical composition, evolution and fate of molecular gas clouds is of special interest, because it is from these clouds that solar systems form. History As an offshoot of the disciplines of astronomy and chemistry, the history of astrochemistry is founded upon the shared history of the two fields. The development of advanced observational and experimental spectroscopy has allowed for the detection of an ever-increas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astrobiology
Astrobiology, and the related field of exobiology, is an interdisciplinary scientific field that studies the origins, early evolution, distribution, and future of life in the universe. Astrobiology is the multidisciplinary field that investigates the deterministic conditions and contingent events with which life arises, distributes, and evolves in the universe. Astrobiology makes use of molecular biology, biophysics, biochemistry, chemistry, astronomy, physical cosmology, exoplanetology, geology, paleontology, and ichnology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth. The origin and early evolution of life is an inseparable part of the discipline of astrobiology. Astrobiology concerns itself with interpretation of existing scientific data, and although speculation is entertained to give context, astrobiology concerns itself primarily with hypotheses that fit firmly into existing scientific ...

Polar Environment Atmospheric Research Laboratory
The Polar Environment Atmospheric Research Laboratory (PEARL) is an atmospheric research facility in the Canadian High Arctic, located on Ellesmere Island, Nunavut. Considered one of the most important Arctic research labs in the world, it was the subject of international media attention when it almost closed due to funding cuts by the Canadian Federal Government in 2012. History PEARL is located on Ellesmere Island, about 15 km from the Eureka Weather Station in Eureka, Nunavut and about 1,100 km from the North Pole. It consists of 3 facilities: the Ridge Lab building, originally built by the Meteorological Service of Canada in 1992 to hold the Arctic Stratospheric Ozone Observatory (AStrO), the Zero (0) Altitude PEARL Auxiliary Laboratory (0PAL) and the Surface Atmospheric Flux and IRradiation Extension (SAFIRE). Full time AStrO operations ended in 2001 due to government budget cuts. After hearing that the Ridge Lab was in danger of being demolished, Canadian Netwo ...
