CRAAG - Bouzareah
The Algiers Observatory was built in the late 19th century in the Algiers suburb of Bouzaréah, Algeria, North Africa. It participated in the Astrographic Catalogue project, taking the zone between -2 and +4 degrees to expose 1,260 plates between the years 1891 and 1911. At the tail end of that time, the director of the installation was François Gonnessiat. It is now known as the Centre de Recherche en Astronomie Astrophysique et Géophysique (CRAAG), where it combines astronomy with work in astrophysics, and geophysical research, including the monitoring of earthquakes. Astronomers Astronomers who worked at the observatory include: * Alfred Schmitt * Benjamin Jekhowsky * Frédéric Sy * Guy Reiss * Joanny-Philippe Lagrula * Louis Boyer * Odette Bancilhon See also * List of astronomical observatories * List of astronomical societies * Lists of telescopes This is a list of lists of telescopes. * List of astronomical interferometers at visible and infrared wavelength ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ...

19th-century French Astronomers
The 19th (nineteenth) century began on 1 January 1801 (Roman numerals, MDCCCI), and ended on 31 December 1900 (Roman numerals, MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolitionism, abolished in much of Europe and the Americas. The Industrial Revolution, First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Gunpowder empires, Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost ...

Discoverers Of Asteroids
Discovery is the act of detecting something new, or something previously unrecognized as meaningful. With reference to sciences and academic disciplines, discovery is the observation of new phenomena, new actions, or new events and providing new reasoning to explain the knowledge gathered through such observations with previously acquired knowledge from abstract thought and everyday experiences. A discovery may sometimes be based on earlier discoveries, collaborations, or ideas. Some discoveries represent a radical breakthrough in knowledge or technology. New discoveries are acquired through various senses and are usually assimilated, merging with pre-existing knowledge and actions. Questioning is a major form of human thought and interpersonal communication, and plays a key role in discovery. Discoveries are often made due to questions. Some discoveries lead to the invention of objects, processes, or techniques. A discovery may sometimes be based on earlier discoveries, collab ...

1714 Sy
1714 Sy, provisional designation , is a stony asteroid from the central regions of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 25 July 1951, by French astronomer Louis Boyer at Algiers Observatory in Algeria, North Africa, and named after French astronomer and orbit computer Frédéric Sy. Orbit ''Sy'' orbits the Sun in the central main-belt at a distance of 2.2–3.0  AU once every 4 years and 1 month (1,503 days). Its orbit has an eccentricity of 0.15 and an inclination of 8 ° with respect to the ecliptic. It was first identified as at Goethe Link Observatory in 1948, extending the body's observation arc by 3 years prior to its official discovery observation at Algiers. Physical characteristics PanSTARRS large-scale survey characterized ''Sy'' as a L-type asteroid, a rare subtype which falls into the broader complex of stony S-type asteroids. Diameter and albedo According to the survey carried out by NASA's Wide-field Infra ...

Valz Prize
The Valz Prize ''(Prix Valz)'' was awarded by the French Academy of Sciences, from 1877 through 1970, to honor advances in astronomy. History The Valz Prize was established in June 1874 when the widow of astronomer Benjamin Valz, Marie Madeleine Julie Malhian, donated 10,000 francs to establish a prize in honor of her late husband. The Valz Prize was to be awarded for work of similar stature as that honored by the pre-existing Lalande Prize. The first Valz Prize was awarded in 1877 to brothers Paul and Prosper Henry, and was for the sum of 460 francs. Save for 1924, the French Academy of Sciences awarded the Valz Prize annually from 1877 to 1943. After 1943, the prize was awarded only sporadically (only once per decade from 1950 to 1970). In 1970 the Valz Prize was combined with the Lalande Prize to create the Lalande-Valz Prize, which continued to be awarded through 1996. In 1997, that prize was combined with numerous other Academy prizes to create the Grande Médaille. List of V ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

He became a well known and respected member of the academic scene of the city, where a street is named after him. From 1908 to 1931, he was director of the Algiers Observatory where one of his colleagues was Benjamin Jekhovsky. He was also director of the Quito Astronomical Observatory. The asteroid 1177 Gonnessia 1177 Gonnessia, provisional designation , is a dark background asteroid from the outer regions of the asteroid belt, approximately 99 kilometers in diameter.
