Last month the National Science Foundation announced plans to eventually decommission Puerto Rico’s Arecibo radio telescope in the near future due to structural weaknesses. Earlier this week the structure did indeed collapse:
The instrument platform of the 305m telescope at Arecibo Observatory in Puerto Rico fell overnight. No injuries were reported. NSF is working with stakeholders to assess the situation. Our top priority is maintaining safety. NSF will release more details when they are confirmed. pic.twitter.com/Xjbb9hPUgD

Today is a tragic day for astronomy, science and for humanity. The Arecibo telescope's platform collapsed this morning, marking the end of any hope for its repair. I wrote about the pain of decommission, but this hurts so much more. @FutureTenseNow https://t.co/LAEf0mKUIp

The NSF released some video of the collapse today:

Stunning video of the moment the Arecibo Observatory telescope platform collapsed and smashed into the dish:

From ABC News:
The telescope collapsed Tuesday morning after showing signs of extreme weakness. The radio-telescope had already suffered major damages after a cable that helped support the 900-ton platform hanging at 450 feet above the dish broke in August. Weeks later, a second cable gave in, putting the telescope at greater risk.
Initial findings show that the top of all three support towers holding the platform ripped, dropping the instrument to the 1,000-foot-wide reflector dish, according to the National Science Foundation.
The dish below was heavily damaged:

Sad day indeed, hopefully there will be efforts for a new project with improved tech. ?

Heartbreaking. I so so hope Arecibo will be rebuilt. https://t.co/36t7aan3Ew

There is now a push to rebuild the observatory, according to a report.
