The largest example of which astronomical instrument is based in arecibo puerto rico?
Its the radio telescope. At 305 meters or 1000 feet, it will be the world's largest until China completes the construction of a 500 meter or 1500 feet diameter one. See the related links for information.
San Juan is the Capital City of Puerto Rico followed by Ponce which is the cultural center on the South side of the island. Mayaguez follows in importance and Arecibo is the fourth largest city on the island. There are 78 municipalities and of these most still retain their Taino names. such as: Mayaguez, Aguada, Arecibo, Jajuya, Humacao, Utuado, Loiza, Caquas, Maunabo etc.
The Search for Extra-Terrestrial Intelligence (SETI) has been going on for many years, primarily with the Arecibo Radio Telescope in Arecibo, Puerto Rico, which began its participation in the programme back in 1999. The dish is 1000 feet across (305 metres) and is the largest single aperture telescope in the world. It took three and a half years to build, beginning in June 1960.
If you are talking about musical instruments, then it is the pipe organ in the Macy's store in Center City Philadelphia. That is the largest functioning musical instrument. The actual largest musical instrument is the pipe organ in the Atlantic City Convention Hall in Atlantic City, NJ. it is much bigger, but only about 10% functioning.
Telescopes can be made to see in almost any part of the electromagnetic spectrum: visible light, infrared light, ultraviolet light, X-rays, or radio waves. The largest telescopes are those for radio waves - in Arecibo there is one with a diameter of 300 meters. I am not sure whether it is the largest, though.
The largest individual radio telescope dish is the Arecibo Radio Telescope at Arecibo in Puerto Rico. It is 305 m in diameter. Most radio telescopes however are made up from arrays of dishes which when used together act as a single detector of large size. The VLA (very Large Array) consists of 27 separate dishes on 3 Y shaped arms 21 km in length. That however is dwarfed by the VLBA (very large baseline array)…
