Arecibo Observatory:

The Arecibo Observatory was a radio telescope in Arecibo, Puerto Rico.

The observatory consisted of a 305 m (1,000 ft) spherical reflector dish built into a natural sinkhole, a cable-mount steerable receiver mounted 150 m (492 ft) above the dish, and several radar transmitters for emitting signals. For more than 50 years, the Arecibo Observatory was the world's largest single-aperture telescope.

The observatory was damaged by Hurricane Maria in 2017 and was affected by earthquakes in 2019 and 2020. After cables broke the support structure for the suspended platform crashed down into the dish. The site is likely to be decommissioned.

Arecibo was primarily used for research in radio astronomy, atmospheric science, and radar astronomy, as well as for programs that search for extraterrestrial intelligence (SETI).

With regards to Einstein@Home, more than 20 pulsars have been found in Arecibo data.

The observatory is a familiar site; it has had several appearances in film, gaming and television productions, such as for the climactic fight scene in the James Bond film GoldenEye.
