Arecibo, Puerto Rico


Arecibo is known as La Villa del Capitán Correa, in memory of a battle fought successfully on its shores by Captain Antonio de los Reyes Correa and a handful of Spanish Army soldiers to repel a British invasion by sea lead by Admiral Whelstone in August 5, 1702.

Settled in 1556, Arecibo became the third Spanish settlement. Founded sixty years later, in 1616, when the King of Spain granted that section of land and the Indians on it to Lope Conchillos, under the governorship of Captain Felipe de Beaumont y Navarra. The leader (Indian chief) of these Indians was called Jamaica Aracibo, their yucayeque was named after him and ultimately the town was called by that same name.

The town is also known as La Muy Leal Villa (very loyal).

It is also home of the world's largest single-dish radio telescope, located 16 km (10 mi) south of Arecibo. The Arecibo Observatory is an astronomical observatory, which was one of the world's most powerful radar-radio telescopes. After 6 decades of service, and recent years of neglet the site no longer serves an observatory, in October 2022, the National Science Foundation (NSF), announced that the dish will not be rebuilt. Instead, NSF plans to transform it into an educational facility. This instrument, when inaugurated in 1963, employed a 1,000-foot (300 meter) spherical reflector consisting of perforated aluminum panels that focus incoming radio waves on movable antenna structures positions about 500 feet (168 meter) above the reflector surface. The antenna was able to moved in any direction, making it possible to track a celestial object in different regions of the sky. It was collecting radio astronomy, terrestrial aeronomy, and planetary radar data for scientists around the world. The telescope was featured in the movies GoldenEye (1995) and Contact (1997).

The National Astronomy and Ionosphere Center developed the observatory and itwas operated and owned by Cornell University under a cooperative agreement with the National Science Foundation. Conceived in 1958 by William E. Gordon, a Cornell professor of electrical engineering, the radio observatory was in operations, since its completion in 1963 and until its collapse in December 2020. The Arecibo Observatory was powerful enough to receive signals transmitted by a comparable telescope located 1,000 light-years away. Scientists from all parts of the world came to this national observatory to carry out research projects. Route 625, Bo. Esperanza, (787) 878-2612.
