To start with, a very short history of radio astronomy would be helpful. Radio astronomy was born in the early 1930s when Karl Jansky, working for Bell Laboratories, was trying to determine the origin of a source of noise that was showing up in receivers operating in the 20 MHz region of the radio spectrum.
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. The observatory is the sole facility of the National Astronomy and Ionosphere Center, which refers to 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-foot (305-metre) radio telescope was the largest single-aperture telescope from its completion in 1963 until July 2016 when the Five hundred meter Aperture Spherical Telescope (FAST) in China was completed.
