Arecibo radio telescope's massive instrument platform has collapsed

On Monday night, the enormous instrument platform that hung over the Arecibo radio telescope's big dish collapsed due to the failure of the remaining cables supporting it. The risk of this sort of failure was the key motivation behind the National Science Foundation's recent decision to shut down the observatory, as the potential for collapse made any attempt to repair the battered scope too dangerous for the people who would do the repairs.

That’s that, it seems. The radio telescope is no more. 😕
