![]() The observatory also includes a smaller radio telescope, a LIDAR facility, and a visitor center, which remain operational after the telescope's collapse. By Ben Evans 7:30 AM The control room had this incredible view of the telescope. The remains of the telescope are being removed as NASA evaluates plans for a replacement instrument. The Sciences Remembering Arecibo Observatory, Two Years After its Collapse The enormous radio dish, which will not be rebuilt, spent nearly six decades scouring the sky for radio signals while nestled in the foothills of Puerto Rico. With its 305m (1000ft) diameter dish constructed in 1963, the Arecibo Observatory continuously provides valuable data for the scientific community and the world. A partial collapse of the telescope occurred on December 1, 2020, before controlled demolition could be conducted. Gordon's persistence culminated in the construction of the Arecibo Observatory which began in the summer of 1960. ![]() ![]() Following two breaks in cables supporting the receiver platform in mid-2020, the NSF decommissioned the telescope. Completed in 1963, it was the world's largest single-aperture telescope for 53 years, surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China. The observatory's main instrument was the Arecibo Telescope, a 305 m (1,000 ft) spherical reflector dish built into a natural sinkhole, with a cable-mount steerable receiver and several radar transmitters for emitting signals mounted 150 m (492 ft) above the dish. In December of 2020, the Arecibo telescope - one of the largest and most iconic astronomical instruments in the world - collapsed. The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Barrio Esperanza, Arecibo, Puerto Rico owned by the US National Science Foundation (NSF). Puerto Ricos Arecibo Observatory began observations in 1963 and gathered crucial data for three different types of science until December 2020, when it collapsed after two support cables.
