Arecibo Observatory, Radio astronomy research center in Arecibo, Puerto Rico.
The Arecibo Observatory contains a 305-meter telescope built inside a natural sinkhole, with research facilities and educational exhibits surrounding the main structure.
The facility, constructed in 1963 as part of the U.S. Department of Defense missile program, operated as the world's largest single-dish radio telescope until 2016.
The observatory educated thousands of students in astronomy and engineering, establishing itself as a central institution for scientific advancement in Puerto Rico.
Following the 2020 telescope collapse, visitors can explore the educational center and learn about space research through interactive displays and guided tours.
Scientists used this facility to transmit the first intentional radio message to potential extraterrestrial civilizations in 1974.
