Public Observatory
A public observatory is an astronomical observatory mainly dedicated to public and educational purposes. It is often supported by a municipality, a school or an astronomical society. The primary purpose of public observatories is to offer extensive programs for public education in astronomy. A second purpose may be to serve as a center for local hobby astronomers or for interested astro-tourists. Some sites are also engaged in special research programs (e.g., programs focused on meteors or asteroids). Public observatories are equipped with several optical telescopes that are housed within a dome or similar structure to protect the instruments from the elements. The domes have a slit in the roof that can be opened during observing and closed when the observatory is not in use. Additional equipment may include astronomical clocks, star maps, PCs, digital projectors, and educational material.

Astronomical Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysics, oceanography and volcanology are examples of disciplines for which observatories have been constructed. The term ''observatoire'' has been used in French since at least 1976 to denote any institution that compiles and presents data on a particular subject (such as public health observatory) or for a particular geographic area (European Audiovisual Observatory). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Historically, ground-based observatories were as simple as containing a mural instrument (for measuring the angle between stars) or Stonehenge (which has some alignments on astronomical phenomena). Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio ...

Public Education
A state school, public school, or government school is a primary school, primary or secondary school that educates all students without charge. They are funded in whole or in part by taxation and operated by the government of the state. State-funded schools are global with each country showcasing distinct structures and curricula. Government-funded education spans from primary to secondary levels, covering ages 4 to 18. Alternatives to this system include homeschooling, Private school, private schools, Charter school, charter schools, and other educational options. By region and country Africa South Africa In South Africa, a state school or government school refers to a school that is state-controlled. These are officially called public schools according to the South African Schools Act of 1996, but it is a term that is not used colloquially. The Act recognised two categories of schools: public and independent. Independent schools include all private schools and schools t ...

Optical Telescope
An optical telescope gathers and focus (optics), focuses light mainly from the visible spectrum, visible part of the electromagnetic spectrum, to create a magnification, magnified image for direct visual inspection, to make a photograph, or to collect data through electronic image sensors. There are three primary types of optical telescope : * ''Refracting telescopes'', which use lens (optics), lenses and less commonly also Prism (optics), prisms (dioptrics) * ''Reflecting telescopes'', which use mirrors (catoptrics) * ''Catadioptric system#Catadioptric telescopes, Catadioptric telescopes'', which combine lenses and mirrors An optical telescope's ability to resolve small details is directly related to the diameter (or aperture) of its objective (optics), objective (the primary lens or mirror that collects and focuses the light), and its light-gathering power is related to the area of the objective. The larger the objective, the more light the telescope collects and the finer det ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

List Of Observatories
This is a partial 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 ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Public Observatories
In public relations and communication science, publics are groups of individual people, and the public (a.k.a. the general public) is the totality of such groupings. This is a different concept to the sociological concept of the ''Öffentlichkeit'' or public sphere. The concept of a public has also been defined in political science, psychology, marketing, and advertising. In public relations and communication science, it is one of the more ambiguous concepts in the field. Although it has definitions in the theory of the field that have been formulated from the early 20th century onwards, and suffered more recent years from being blurred, as a result of conflation of the idea of a public with the notions of audience, market segment, community, constituency, and stakeholder. Etymology and definitions The name "public" originates with the Latin '' publicus'' (also '' poplicus''), from ''populus'', to the English word ' populace', and in general denotes some mass population ("the ...

Amateur Astronomy
Amateur astronomy is a hobby where participants enjoy observing or imaging celestial objects in the sky using the Naked eye, unaided eye, binoculars, or telescopes. Even though scientific research may not be their primary goal, some amateur astronomers make contributions in doing citizen science, such as by monitoring variable stars, double stars, sunspots, or occultations of stars by the Moon or asteroids, or by discovering transient astronomical events, such as comets, galactic novae or supernovae in other galaxy, galaxies. Amateur astronomers do not use the field of astronomy as their primary source of income or support, and usually have no professional degree in astrophysics or advanced academic training in the subject. Most amateurs are hobbyists, while others have a high degree of experience in astronomy and may often assist and work alongside professional astronomers. Many astronomers have studied the sky throughout history in an amateur framework; however, since the be ...
