The remains of the telescope are being removed as NASA evaluates plans for a replacement instrument. A partial collapse of the telescope occurred on December 1, 2020, before controlled demolition could be conducted. Following two breaks in cables supporting the receiver platform in mid-2020, the NSF decommissioned the telescope.

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. ![]() At 2 a.m., she had one precious hour to focus the 305-meter dish on NGC 7469, a distant galaxy. In 1974, the most powerful broadcast ever deliberately beamed into space was made from Puerto Rico. ![]() 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). In the early morning of 10 August 2020, Sravani Vaddi, a postdoc astronomer at the Arecibo Observatory in Puerto Rico, was working from home, but her thoughts were at Arecibo's giant radio telescope. ![]()
