Solar Submillimeter Telescope
The Solar Submillimeter Telescope (SST) is a solar dedicated instrument with the aim to study the radiation produced by high-energy particles during solar flares. Observing at 212 and 405 GHz with a focal array since 2001, it is a unique instrument that has produced a wealth of new information. ''Some of its discoveries are still unexplained by current theories''. SST construction started in 1995, and it saw the ''first light'' in April 1999; since April 2001 it operates on a daily basis. It is installed at Complejo Astronomico El Leoncito (San Juan Province, Argentina) under agreement between the Argentinian National Scientific and Technical Research Council National may refer to: Common uses * Nation or country ** Nationality – a ''national'' is a person who is subject to a nation, regardless of whether the person has full rights as a citizen Places in the United States * National, Maryland, c ...

Solar Flare
A solar flare is an intense localized eruption of electromagnetic radiation in the Sun's atmosphere. Flares occur in active regions and are often, but not always, accompanied by coronal mass ejections, solar particle events, and other solar phenomena. The occurrence of solar flares varies with the 11-year solar cycle. Solar flares are thought to occur when stored magnetic energy in the Sun's atmosphere accelerates charged particles in the surrounding plasma. This results in the emission of electromagnetic radiation across the electromagnetic spectrum. High-energy electromagnetic radiation from solar flares is absorbed by the daylight side of Earth's upper atmosphere, in particular the ionosphere, and does not reach the surface. This absorption can temporarily increase the ionization of the ionosphere which may interfere with short-wave radio communication. The prediction of solar flares is an active area of research. Flares also occur on other stars, where the term ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Astronomy And Astrophysics Review
''The Astronomy and Astrophysics Review'' is a peer-reviewed scientific journal that is published quarterly by Springer-Verlag GmbH Germany, part of Springer_Nature. The editor-in-chief is Francesca Matteucci. The first issue was published in April 1989. Scope The journal publishes invited reviews on all areas of astronomy and astrophysics, including cosmic ray physics, studies in the solar system, astrobiology, developments in laboratory or particle physics directly relevant to astronomy, instrumentation Instrumentation a collective term for measuring instruments that are used for indicating, measuring and recording physical quantities. The term has its origins in the art and science of scientific instrument-making. Instrumentation can refer to ..., computational or statistical methods with specific astronomical applications, and other subjects relevant to astronomy and astrophysics.

Complejo Astronomico El Leoncito
The El Leoncito Astronomical Complex (Spanish: Complejo Astronómico El Leoncito - CASLEO) is an astronomical observatory in the San Juan Province of Argentina. CASLEO is one of two observatories located within El Leoncito National Park, which is in a part of the country which rarely sees cloud cover. The other facility in the park is the Carlos U. Cesco Astronomical Station of the Félix Aguilar Observatory. CASLEO was established in 1983 by an agreement between National Scientific and Technical Research Council (CONICET) of Argentina, the Ministry of Science, Technology and Innovation (MINCYT) of Argentina, the National University of San Juan (UNSJ), the National University of La Plata (UNLP), and the National University of Córdoba (UNC). The facility was dedicated in 1986 and regular observations began in 1987. CASLEO's telescopes are located in two separate areas within the El Leoncito Park. The Jorge Sahade and Submillimeter telescopes are at the main site on the edge o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Juan Province, Argentina
San Juan Province () is a province of Argentina, located in the western part of the country. Neighbouring provinces are, moving clockwise from the north, La Rioja, San Luis and Mendoza. It borders with Chile to the west. The province has an area of 89,651 km2, covering a mountainous region with scarce vegetation, fertile oases and turbulent rivers. Throughout the entire province there are an important number of paleontological sites. Similar to other regions in Argentina, agriculture is one of the most important economic activities, highlighting wine production and olive oil. Additionally, a variety of fruits and vegetables are produced in the fertile valleys irrigated by artificial channels in the western part, close to the Andes mountain range. This is the second province in volume of wine production at the national level and in South America, and possesses outstanding varietal wines. It is also an important center of mining and oil production. History Before the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Universidade Presbiteriana Mackenzie
Mackenzie Presbyterian University ( Portuguese: ''Universidade Presbiteriana Mackenzie'') is a private university in São Paulo, Brazil. The Mackenzie Presbyterian University is an institution of higher learning that has strong tradition and history in Brazil. It has campuses for undergraduate and postgraduate studies in São Paulo (Campus Higienópolis), Campinas, Barueri (Campus Alphaville), Brasilia, Curitiba and Rio de Janeiro Founded in 1870 as the American School, Mackenzie is one of the oldest institutions of higher education in Brazil. The university is regarded nationally and internationally as a center of excellence having graduated numerous important names in Brazilian history. History In 1870, the American Presbyterian missionary Rev. George Whitehill Chamberlain and his wife Mary Annesley founded a private grammar school inside their home. The classes were held in their living room and, a few years later, the "American School" was established as a center of excell ...

Radio Telescopes
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 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
