TRAPPIST-North
The Transiting Planets and Planetesimals Small Telescope (TRAPPIST) is the corporate name for a pair of Belgian optic robotic telescopes. TRAPPIST–South, which is situated high in the Chilean mountains at the European Southern Observatory's La Silla Observatory, came online in 2010, and TRAPPIST–North situated at the Oukaïmeden Observatory in the Atlas Mountains in Morocco, came online in 2016. Description TRAPPIST is controlled from Liège, Belgium, with some autonomous features. It consists of two reflecting robotic telescopes located at the ESO La Silla Observatory (housed in the dome of the retired Swiss T70 telescope) in Chile and at Oukaïmeden Observatory in Morocco. The 60 cm f/8 Ritchey–Chrétien design telescopes and New Technology Mount NTM-500 were built by ASTELCO Systems, a company in Germany.

University Of Liège
The University of Liège (), or ULiège, is a major public university of the French Community of Belgium founded in 1817 and based in Liège, Wallonia, Belgium. Its official language is French (language), French. History The university was founded in 1817 by William I of the Netherlands, then King of the United Kingdom of the Netherlands, and by his Minister of Education, Anton Reinhard Falck. The foundation of the university was the result of a long intellectual tradition which dates back to the origins of the Prince-Bishopric of Liège. Beginning in the eleventh century, the influence of the principality attracted students and prominent scientists and philosophers, such as Petrarch, to study in its libraries. The reputation of its medieval schools gave the city the reputation as Athens#Cities nicknamed "Athens", a new Athens. A 17 March 1808 decree by Napoleon I of France, Napoleon I concerning the organization of an imperial university indicated Liège as the site of a new ac ...

Robotic Telescope
A robotic telescope is an astronomical telescope and detector system that makes observations without the intervention of a human. In astronomical disciplines, a telescope qualifies as robotic if it makes those observations without being operated by a human, even if a human has to initiate the observations at the beginning of the night or end them in the morning. It may have software agents using artificial intelligence that assist in various ways such as automatic scheduling. A robotic telescope is distinct from a remote telescope, though an instrument can be both robotic and remote. By 2004, robotic observations accounted for an overwhelming percentage of the published scientific information on asteroid orbits and discoveries, variable star studies, supernova light curves and discoveries, comet orbits and gravitational microlensing observations. All early phase gamma ray burst observations were carried by robotic telescopes. Design Robotic telescopes are complex systems tha ...

Eris (dwarf Planet)
Eris (minor-planet designation: 136199 Eris) is the most massive and second-largest known dwarf planet in the Solar System. It is a trans-Neptunian object (TNO) in the scattered disc, scattered disk and has a high-Orbital eccentricity, eccentricity orbit. Eris was discovered in January 2005 by a Palomar Observatory–based team led by Michael E. Brown, Mike Brown and verified later that year. It was named in September 2006 after the GrecoRoman Eris (mythology), goddess of strife and discord. Eris is the List of Solar System objects by size, ninth-most massive known object orbiting the Sun and the sixteenth-most massive overall in the Solar System (counting natural satellite, moons). It is also the largest known object in the Solar System that has not been visited by a spacecraft. Eris has been measured at in diameter; its mass is 0.28% that of the Earth mass, Earth and 27% greater than that of Pluto, although Pluto is slightly larger by volume. Both Eris and Pluto have a sur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
First Light (astronomy)
In astronomy, first light is the first use of a telescope (or, in general, a new instrument) to take an astronomical image after it has been constructed. This is often not the first viewing using the telescope; optical tests will probably have been performed to adjust the components. Characteristics The first light image is normally of little scientific interest and is of poor quality, since the various telescope elements are yet to be adjusted for optimum efficiency. Despite this, a first light is always a moment of great excitement, both for the people who design and build the telescope and for the astronomical community, who may have anticipated the moment for many years while the telescope was under construction. A well-known and spectacular astronomical object An astronomical object, celestial object, stellar object or heavenly body is a naturally occurring physical entity, association, or structure that exists within the observable universe.

Comet ISON
Comet ISON, formally known as C/2012 S1, was a sungrazing comet from the Oort cloud which was discovered on 21 September 2012 by Vitaly Nevsky (Віталь Неўскі, Vitebsk, Belarus) and Artyom Novichonok (Артём Новичонок, Kondopoga, Russia). History The discovery was made using the reflecting telescope, reflector of the International Scientific Optical Network (ISON) near Kislovodsk, Russia. Data processing was carried out by automated asteroid-discovery program CoLiTec. Precovery images by the Mount Lemmon Survey from 28 December 2011 and by Pan-STARRS from 28 January 2012 were quickly located. Follow-up observations were made on 22 September 2012 by a team from Remanzacco Observatory in Italy using the iTelescope network. The discovery was announced by the Minor Planet Center on 24 September. Observations by Swift Gamma-Ray Burst Mission, Swift in January 2013 suggested that Comet ISON's comet nucleus, nucleus was around in diameter. Later estimates wer ...

Trappist Beer
Trappist beer is brewed by Trappist monks. Thirteen Trappist monasteries—six in Belgium, two in the Netherlands, and one each in Austria, Italy, England, France, and Spain— produce beer, but the ''Authentic Trappist Product'' label is assigned by the International Trappist Association (ITA) to just ten breweries that meet their strict criteria. , Achel is no longer recognized as a Trappist brewery because it does not have any monks. History The Catholic Trappist order originated in the Cistercian monastery of La Trappe, France. Various Cistercian congregations existed for many years, and by 1664 the abbot of La Trappe felt that the Cistercians were becoming too liberal. He introduced strict new rules in the abbey and the Strict Observance was born. Since this time, many of the rules have been relaxed. However, a fundamental tenet that monasteries should be self-supporting is still maintained by these groups. Monastery brewhouses, from different religious orders, have existed ...

Backronym
A backronym is an acronym formed from an already existing word by expanding its letters into the words of a phrase. Backronyms may be invented with either serious or humorous intent, or they may be a type of false etymology or folk etymology. The word is a portmanteau of ''back'' and ''acronym''. A normal acronym is a word derived from the initial letter(s) of the words of a phrase, such as ''radar'' from "radio detection and ranging". By contrast, a backronym is "an acronym deliberately formed from a phrase whose initial letters spell out a particular word or words, either to create a memorable name or as a fanciful explanation of a word's origin". Many list of fictional espionage organizations, fictional espionage organizations are backronyms, such as SPECTRE (special executive for counterintelligence, terrorism, revenge and extortion) from the ''James Bond'' franchise. For example, the Amber Alert missing-child program was named after Amber Hagerman, a nine-year-old girl w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SPECULOOS
Speculoos (; ; ) is a biscuit, originally manufactured in Belgium, made from wheat flour, candy syrup (from beet sugar), fat, and sometimes cinnamon. Speculoos were developed in the 20th century around the area of Verviers, as an alternative for people who could not afford Dutch speculaas. Belgian Speculoos includes fewer spices than Dutch speculaas, as the spices were much more expensive to import to Belgium than to the Netherlands. The origins of speculaas are much older. In the 2020s the names ''speculaas'' and ''speculoos'' are sometimes used interchangeably in Flanders. Brands In Europe, Lotus Speculoos is the most recognized brand. This manufacturer supplied the biscuits individually packaged to the catering industry. In the United States and the United Kingdom, the same company is branded as Lotus Biscoff, short for ''biscuit with coffee''. Company founder Jan Boone Sr. created the original recipe in 1932. In October 2020, Lotus Bakeries decided to omit the word "sp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Circumstellar Habitable Zone
In astronomy and astrobiology, the habitable zone (HZ), or more precisely the circumstellar habitable zone (CHZ), is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure.J. F. Kasting, D. P. Whitmire, R. T. Reynolds, Icarus 101, 108 (1993). The bounds of the HZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun. Due to the importance of liquid water to Earth's biosphere, the nature of the HZ and the objects within it may be instrumental in determining the scope and distribution of planets capable of supporting Earth-like extraterrestrial life and intelligence. As such, it is considered by many to be a major factor of planetary habitability, and the most likely place to find extraterrestrial liquid water and biosignatures elsewhere in the universe. The habitable zone is also called the Goldilocks zone, a metaphor, allusion and antonomasia of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transit Photometry
Methods of detecting exoplanets usually rely on indirect strategies – that is, they do not directly image the planet but deduce its existence from another signal. Any planet is an extremely faint light source compared to its parent star. For example, a star like the Sun is about a billion times as bright as the reflected light from any of the planets orbiting it. In addition to the intrinsic difficulty of detecting such a faint light source, the glare from the parent star washes it out. For those reasons, very few of the exoplanets reported have been detected directly, with even fewer being resolved from their host star. Established detection methods The following methods have proven successful at least once for discovering a new planet or detecting an already discovered planet: Radial velocity A star with a planet will move in its own small orbit in response to the planet's gravity. This leads to variations in the speed with which the star moves toward or away from Ea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
