	WTD. Arecibo Observatory
		The Arecibo Observatory is part of the National Astronomy and Ionosphere Center (NAIC), a national research center operated by Cornell University under a cooperative agreement with the National Science Foundation (NSF).
		Use of the Arecibo Observatory is available on an equal, competitive basis to all scientists from throughout the world.
		However, the assault on Arecibo comes on two fronts -- while electronic emissions encroach from the air, on the ground of this former 15 th -century Spanish colony in the Caribbean, the tropical forest forever attempts to consume the structure.

		The Arecibo telescope is one of the most famous such telescopes in the world, distinguished by its enormous size; the main collecting dish is 305 meters in diameter, constructed inside the depression left by a karst sinkhole.
		The construction of the Arecibo telescope was initiated by Professor William E. Gordon[?] of Cornell University, who originally intended to use it for the study of Earth's ionosphere.
		Arecibo was also the source of data for the SETI@home[?] distributed-computing project put forward by the SETI Institute.

	Arecibo Observatory Atmospheric Sciences Exhibit
		The Arecibo Observatory was originally built as the world's premier radar facility to study the upper part of the atmosphere called the ionosphere, where many of the harmful wavelengths of solar and cosmic radiation are filtered out.
		The Arecibo radar is able to measure ionospheric parameters, including the types and amounts of gases present, their temperatures, and the direction and speed of the winds.
		Another important instrument at Arecibo is the HF (high frequency) facility, which is an upward-pointing shortwave radio transmitter used to study plasma waves and turbulence in the ionosphere.

	Major Upgrade To Arecibo Observatory Passes Critical Milestone
		ARECIBO, Puerto Rico -- The Arecibo Observatory, home of the world's largest radio-radar telescope, has moved close to completion of a major upgrade that makes it one of the most sensitive and powerful tools ever designed for astronomical studies.
		The upgrade gives the Arecibo telescope such better sensitivity: It could be used to listen into a cellular telephone call on Venus; the radar could detect a steel golf ball at the distance of the moon.
		A spherical reflector such as the Arecibo dish does not focus radio waves to a point as does a parabolic satellite antenna, but the symmetry properties of a sphere mean that it is possible to "steer" the telescope to look in different directions by moving the focusing system rather than the entire 1,000-foot reflector.

		Arecibo is also well suited to study the chemistry of star formation.
		The Arecibo Observatory is a radio/radar telescope that uses electromagnetic radiation, or radio waves, to study phenomena that occur as close as 3km (about 2 miles) above Earth in the upper atmosphere, or exotic cosmic objects many billions of light years away, at the edge of the known universe.

	The Arecibo Observatory
		The Observatory had its origins in an idea of Professor William E. Gordon, then of Cornell University, who was interested in the study of the Ionosphere.
		Gordon's persistence culminated in the construction of the Arecibo Observatory which began in the Summer of 1960.
		The Arecibo site offered the advantage of being located in Karst terrain, with large limestone sinkholes which provided a natural geometry for the construction of the 305 meter reflector.

		Cosmic radio signals are so weak, in fact, that all the energy collected by all the radio telescopes on our planet during the 60+ year history of radio astronomy amounts to no more than the energy released when a few raindrops hit the ground.
		No. The Arecibo system operates at frequencies between 50 and 10,000 megohertz, corresponding to a range of wavelengths between 6 meters and 3 centimeters.

	More UFOs At The Arecibo Radio Observatory
		Such a remark contradicts the statements of the Arecibo Radio Observatory scientific officers and technicians in the sense that there is no such thing as the UFO phenomenon or possible alien based incidents.
		Also, as a matter of fact, there have been a series of very significant events in the zone where the Radio Observatory is located at, events that indicate that unidentified flying objects, or those those who control them, watch closely the activities and research being made there.
		They also responded to us when we asked them about it, that the scientific officers or directors of the Arecibo Radio Observatory have never prohibited them to speak out on the subject, but they also stated that as a matter of fact the UFO subject is not discussed there at all.

		The Arecibo message is a radio message that was beamed into space at a ceremony to mark the remodeling of the Arecibo radio telescope in 1974.
		It was aimed at the globular star cluster M13 some 25,000 light years away because it was a large and close collection of stars that was available in the sky at the time and place of the ceremony.
		A crop circle containing a modified form of the Arecibo message was found near Chilbolton's Observatory, depicting a grey in place of the human figure.

		The biggest telescope out there is the 305m radio telescope at Arecibo Observatory.
		The Arecibo Observatory is often used for SETI projects (among many other scientific research projects) and is also highly recognizable because it has been used in Contact by Ellie (the lead character) and as part of the villain’s evil plan in James Bond’s GoldenEye.
		The Subaru Telesctop is one of Mauna Kea’s Observatories along with the 10m Keck Telescope (which is not pictured here because the resolution is too low).
