The famous Arecibo radio telescope in Puerto Rico, which has provided an invaluable service to scientists for 57 years as well as establishing itself in popular culture, will be dismantled after it incurred irreparable damage in recent months.

The enormous observatory was completed in 1963 and immediately established itself as a powerful tool for astronomers and atmospheric scientists around the world. The enormous instrument boasted a larger size and different architecture than anything before it, opening up new possibilities for monitoring the universe (and transmitting to it, not something every array can do).
