Puerto Rico’s huge radio telescope collapses

A huge radio telescope in Puerto Rico that has long played a key role in astronomical discoveries has collapsed, officials say.

The Arecibo Observatory had been closed since August after an auxiliary cable snapped and caused a 30-meter gash in the reflector.

Then a main cable broke in early November, leading the National Science Foundation to declare a few weeks later that it planned to shut down the radio telescope because the damage was too great.

Many scientists and Puerto Ricans mourned the news, with a few snags during interviews.

It is the second largest radio telescope in the world and has been in operation for more than half a century.
