The Arecibo Observatory in Puerto Rico, the second-largest radio telescope in the world and iconic in pop culture,  is to be decommissioned after being damaged irreparably. 

The observatory opened 57 years ago and remains a focal point for solar system and geospace research. The dish probes space for everything from unexplained radio signals, to planets, to signs of alien life. The telescope's loss will be felt deeply among the global community of scientists who used its capabilities to understand our universe.
