Arecibo Observatory
The Arecibo Observatory is a radio telescope in the municipality of Arecibo, Puerto Rico. This observatory is operated by SRI International, USRA and UMET, under cooperative agreement with the National Science Foundation (NSF). This observatory is also called the National Astronomy and Ionosphere Center, although ""NAIC"" refers to both the observatory and the staff that operates it. From its construction in the 1960s until 2011, the observatory was managed by Cornell University.The Observatory's 1,000 ft (305 m) radio telescope is the world's largest single-aperture telescope. It is used in three major areas of research: radio astronomy, atmospheric science, and radar astronomy. Scientists who want to use the Arecibo Telescope submit proposals that are evaluated by an independent scientific board.The Radio Telescope has made appearances in motion picture and television productions, gaining more recognition in 1999 when it began to collect data for the SETI@home project. It has been listed on the American National Register of Historic Places beginning in 2008. It was the featured listing in the National Park Service's weekly list of October 3, 2008. The Center was named in IEEE Milestone in 2001. It has a visitors center that is open part time.
