Astronomical Observatory
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 dur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spanish Navy
The Spanish Navy or officially, the Armada, is the Navy, maritime branch of the Spanish Armed Forces and one of the oldest active naval forces in the world. The Spanish Navy was responsible for a number of major historic achievements in navigation, the most famous being the voyages of Christopher Columbus, discovery of America and the Magellan's circumnavigation, first global circumnavigation by Juan Sebastián Elcano, Elcano. For several centuries, it played a crucial logistical role in the expansion and consolidation of the Spanish Empire, and defended a vast trade network across the Atlantic Ocean between the Spanish treasure fleet, Americas and Europe, and the Manila Galleon across the Pacific Ocean between the Spanish East Indies, Philippines and the Americas. The Spanish Navy was the most powerful maritime force in the world from the late 15th century to the early 18th century. In the early 19th century, with the Spanish American wars of independence, loss of most of its e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Fernando, Cádiz
San Fernando (, "Saint Ferdinand") is a town in the province of Cádiz, Spain. It is home to more than 97,500 inhabitants. The city also uses the name "''La Isla''" (The Island). The people from San Fernando are locally known as "''Cañaíllas''" or "''Isleños''". History In history, the city played a paramount role when in 1810 during the French occupation led by Napoleon, San Fernando and Cádiz were the only parts of Spain which did not surrender to the French. The deputies elected to the Cortes of Cádiz met in the Teatro Cómico, and started preparation of the first liberal constitution of Spain, which was approved in the neighbouring city of Cádiz in 1812. Flamenco singer Camarón de la Isla was born in San Fernando. It holds the Panteón de Marinos Ilustres.

Royal Observatory Of Madrid
The Royal Observatory of Madrid is a historic observatory situated on a small hill next to the Buen Retiro Park in Madrid, Spain. It was completed in 1790 and took over some of the work previously done by the naval observatory on the south coast. It is the seat of the Spanish National Astronomical Observatory and the Observatorio Geofísico Central, both administered by the National Geographic Institute (via its department of ''Astronomía, Geofísica y Aplicaciones Espaciales''). Architecture The observatory was designed by Juan de Villanueva, architect to Charles III of Spain, It represents one of the highlights of Spanish neoclassical architecture. Its domed lantern was conceived as a classical circular temple. Equipment Shortly after construction, the observatory was equipped with a 25-foot reflecting telescope by William Herschel. The instrument was dismantled in the Peninsular War and only partially survived. It has been reconstructed in recent years. Current use Madri ...

Light Pollution
Light pollution is the presence of unwanted, inappropriate, or excessive use of artificial lighting. In a descriptive sense, the term ''light pollution'' refers to the effects of any poorly implemented lighting, during the day or night. Light pollution can be understood not only as a phenomenon resulting from a specific source or kind of pollution, but also as a contributor to the wider, collective impact of various sources of pollution. Although this type of pollution can exist throughout the day, its effects are magnified during the night with the contrast of darkness. It has been estimated that 83 percent of the world's people live under light-polluted skies and that 23 percent of the world's land area is affected by skyglow. The area affected by artificial illumination continues to increase. A major side-effect of urbanization, light pollution is blamed for compromising health, disrupting ecosystems, and spoiling aesthetic environments. Globally, it has increased by at least ...

Space Junk
Space debris (also known as space junk, space pollution, space waste, space trash, or space garbage) are defunct human-made objects in space—principally in Earth orbit—which no longer serve a useful function. These include derelict spacecraft—nonfunctional spacecraft and abandoned launch vehicle stages—mission-related debris, and particularly numerous in Earth orbit, fragmentation debris from the breakup of derelict rocket bodies and spacecraft. In addition to derelict human-made objects left in orbit, other examples of space debris include fragments from their disintegration, erosion and collisions or even paint flecks, solidified liquids expelled from spacecraft, and unburned particles from solid rocket motors. Space debris represents a risk to spacecraft. Space debris is typically a negative externality—it creates an external cost on others from the initial action to launch or use a spacecraft in near-Earth orbit—a cost that is typically not taken into accoun ...

Time Ball
A time ball or timeball is a time-signalling device. It consists of a large, painted wooden or metal ball that is dropped at a predetermined time, principally to enable navigators aboard ships offshore to verify the setting of their marine chronometers. Accurate timekeeping is essential to the determination of longitude at sea. Although time balls have since been replaced by electronic time signals, some time balls have remained operational as historical tourist attractions. History The fall of a little ball was in antiquity a way to show to people the time. Ancient Greek clocks had this system in the main square of a city, as in the city of Gaza in the post-Alexander era, and as described by Procopius in his book on Edifices. Time ball stations set their clocks according to transit observations of the positions of the sun and stars. Originally they either had to be stationed at the observatory, or had to keep a very accurate clock at the station which was set manually to observ ...

ROA Time
ROA Time is the official time of Spain. It is established by ROA, the Royal Institute and Observatory of the ''Armada'' (Armada being the name of the Spanish Navy in Spanish), at San Fernando, Cádiz. Broadcasting methods ROA broadcasts the official time in Spain using the following methods: # Transmission of time signals in HF in two daily intervals of 25 minutes. From 10:00 UTC to 10:25 UTC on 15.006 MHz and from 10:30 UTC to 10:55 UTC on 4.998 MHz. The station is a Harris RF-130 with 1kW of power broadcasting from San Fernando (Cádiz). This is the only radio broadcast of official time in Spain as there is no longwave station broadcasting time signals such as DCF77 from Germany or MSF60 (also known as NPL) from the United Kingdom. # Via hotline (Phone number: +34 956 59 94 29), using a time information broadcasting protocol widely used in Europe (European Telephone Code Standard). Access is limited to two minutes per call and admits international calls. # NTP Pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomical Observatories In Spain
Astronomy () is a natural science that studies celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and evolution. Objects of interest include planets, moons, stars, nebulae, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonians, Greeks, Indians, Egyptians, Chinese, Maya, and many ancient indigenous peoples of the Americas. In the past, astronomy included disciplines as diverse as astrometry, celestial navigation, observational astronomy, and the making of calendars. Nowad ...
