Dramatic video from captures the moment when a 816-tonne platform came crashing down on the Arecibo Observatory, shattering one of the world’s largest telescopes and striking a crushing blow to the global scientific community. The catastrophic collapse happened on Dec. 1, less than two weeks after the U.S. National Science Foundation (NSF) warned that such a disaster was imminent. The NSF had already shuttered operations at the facility after a suspension cable snapped and slashed a hole in the dish last month. The telescope was the largest of its kind when it opened in 1963, and it has contributed to all manner of astronomical discoveries over the years, from asteroids to planets to mysterious radio signals in space. It also won a place in pop culture as the set for such films as Contact and GoldenEye, the first James Bond movie starring Pierce Brosnan.
