Arecibo - Arecibo Radio Telescope Observatorio de Arecibo

The Observatorio de Arecibo (Arecibo Radio Telescope) features a 20ac/8ha dish set in a sinkhole. Here, astronomers have proved the "music of the stars" (pulsars and quasars) and examine the moon, the earth's ionosphere, and other planets. There is an ongoing Search for Extraterrestrial Intelligence (SETI) program at the site as well. Also, scenes from the Jodi Foster film Contact and others have been filmed at the observatory.

The setting is amazing and the complexity of the Observatorio de Arecibo is so impressive it is well worth the drive up the winding road that leads here.
