Some incredibly concerning news out of Puerto Rico today. An auxiliary cable supporting the massive 900-ton instrument platform at the iconic Arecibo Observatory has snapped, tearing a 100-foot hole through the main reflector dish beneath.



Arecibo has been an absolute titan of radio astronomy for decades, famous not just for its scientific discoveries—like finding the first exoplanets around a pulsar—but also for its appearances in popular culture. Engineers are currently assessing the damage, but the structural integrity of the entire facility is now a major concern. It is a sobering reminder of the fragility of our ageing astronomical infrastructure.
