Côte D'Azur Observatory
The Côte d'Azur Observatory (french: Observatoire de la Côte d'Azur, OCA) is a network of astronomical observatories throughout southern France. It originated in 1988 with the merger of two observatories: # Nice Observatory # Centre de recherches en géodynamique et astrométrie (CERGA) Cote d'Azure Observatory tested beam combining technology at CHARA array. Astronomers developed a theory about M-Type asteroids, that may be tested by the planned spacecraft ''Psyche''.

Astronomical Observatories
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nice Observatory
The Nice Observatory (french: Observatoire de Nice) is an astronomical observatory located in Nice, France on the summit of Mount Gros. The observatory was founded in 1879, by the banker Raphaël Bischoffsheim. The architect was Charles Garnier, and Gustave Eiffel designed the main dome. In 1886 the largest refracting (i.e., with an objective lens rather than a mirror) telescope in the World made its debut at Nice Observatory, the ''Grand Lunette.'' Description The refractor telescope made by Henry and Gautier became operational around 1886–1887, was the largest in a privately funded observatory, and the first at such high altitude ( above sea level). It was slightly bigger in aperture, several metres longer, and located at a higher altitude than the new (1895) at Pulkovo observatory in the Russian Empire, and the at Vienna Observatory (completed early 1880s). In the records for the largest refracting telescopes all three were outperformed by the refractor installed at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centre De Recherches En Géodynamique Et Astrométrie
The CERGA Observatory (french: Centre de recherches en géodynamique et astrométrie; obs. code: 010) was a scientific department and astronomical station of the Côte d'Azur Observatory in southern France, where several asteroids were discovered during 1984–1993. Description CERGA included 28 researchers and as many engineers and technicians located on the Observatory sites of Nice, Grasse and Calern (Caussols). The scientific activities covered fields as diverse as fundamental astronomy, celestial mechanics, and space geodesy. CERGA was in charge of several observing facilities of the Lunar Laser Ranging experiment, for example, the lunar-laser ranging telescope and the two satellite laser stations. By nature the scientific activity involved the acquisition of data and their processing, a dedicated instrumental development and a close relationship with the more theoretical aspects in dynamics and observation modelling. CERGA was dissolved in 2004 when the parent Côte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CHARA Array
The CHARA (Center for High Angular Resolution Astronomy) array is an optical interferometer, located on Mount Wilson, California. The array consists of six telescopes operating as an astronomical interferometer. Construction was completed in 2003. CHARA is owned by Georgia State University (GSU). Functionality CHARA’s six telescopes each have a one-meter diameter mirror to reflect light. They are spread across Mount Wilson to increase the angular resolution of the array. Each of the six telescopes provides a different image, to combine it into one image the light from each telescope is transported through vacuum tubes and fed into a single beam, where they are matched up to within one micron. This process is called interferometry, and allows the array to have the same resolving power as a telescope with a 330-meter mirror, and an angular resolution of 200 micro-arcseconds. History In 1984 CHARA was founded, and with financial support from the National Science Foundation ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M-type Asteroid
M-type (aka M-class) asteroids are a spectral class of asteroids which appear to contain higher concentrations of metal phases (e.g. iron-nickel) than other asteroid classes, and are widely thought to be the source of iron meteorites. Definition Asteroids are classified as M-type based upon their generally featureless and flat to red-sloped absorption spectra in the visible to near-infrared and their moderate optical albedo. Along with the spectrally similar E-type and P-type asteroids (both categories E and P were formerly type-M in older systems), they are included in the larger X-type asteroid group and are distinguishable only by optical albedo: : Characteristics Composition Although widely assumed to be metal-rich (the reason for use of "M" in the classification), the evidence for a high metal content in the M-type asteroids is only indirect, though highly plausible. Their spectra are similar to those of iron meteorites and enstatite chondrites, and radar observations ha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psyche (spacecraft)
''Psyche'' is a planned orbiter mission to explore the origin of planetary cores by studying the metallic asteroid of the same name. Lindy Elkins-Tanton of Arizona State University is the principal investigator who proposed this mission for NASA's Discovery Program. NASA's Jet Propulsion Laboratory (JPL) will manage the project. 16 Psyche is the heaviest known M-type asteroid, and was once thought to be the exposed iron core of a protoplanet, the remnant of a violent collision with another object that stripped off its mantle and crust. Numerous recent studies have all but ruled that out. Radar observations of the asteroid from Earth indicate an iron–nickel composition. On January 4, 2017, the ''Psyche'' mission was selected for NASA's Discovery #14 mission, and launch was scheduled for no earlier than September 20, 2022. On June 24, 2022, the Psyche launch was postponed until at least 2023. As of October 2022, Psyche is scheduled to launch no earlier than October 10 ...

List Of Astronomical Observatories
This is a list of astronomical observatories ordered by name, along with initial dates of operation (where an accurate date is available) and location. The list also includes a final year of operation for many observatories that are no longer in operation. While other sciences, such as volcanology and meteorology, also use facilities called observatories for research and observations, this list is limited to observatories that are used to observe celestial objects. Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Many modern telescopes and observatories are located in space to observe astronomical objects in wavelengths of the electromagnetic spectrum that cannot penetrate the Earth's atmosphere (such as ultraviolet radiation, X-rays, and gamma rays) and are thus impossible to observe using ground-based telescopes. Being above the atmosphere, these space observatories can also avoid the effects of atmo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
