Arecibo Observatory, Astronomical observatory in Puerto Rico
The main structure consisted of a radio telescope featuring a metal dish measuring 305 meters across, set within a natural limestone sinkhole.
Cornell University managed the facility from its inauguration in 1963 until 2011, conducting research in atmospheric science and radio astronomy.
Multiple scientific discoveries made at the observatory included the first binary pulsar, leading to research that confirmed Einsteins theory of gravity.
Before its collapse, researchers used the telescope to study planets, asteroids, and distant galaxies through radio waves and radar technology.
The platform containing the receiver equipment fell into the dish on December 1, 2020, ending the operational life of this research facility.
