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.

The dish below was heavily damaged:


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