Huge Puerto Rico radio telescope, already damaged, collapses

·1 min read

ARECIBO, Puerto Rico — A huge, already damaged radio telescope in Puerto Rico that has played a key role in astronomical discoveries for more than half a century has now completely collapsed. The telescope’s 900-ton receiver platform fell onto the reflector dish more than 400 feet below on Tuesday. The U.S. National Science Foundation had earlier announced that the Arecibo Observatory would be closed. An auxiliary cable snapped in August, causing a 100-foot gash on the 1,000-foot-wide (305-meter-wide) reflector dish and damaged the receiver platform that hung above it. Then a main cable broke in early November.
