Arecibo Observatory Facts and Features

In 1958, Bill Gordon proposed building a large telescope in Puerto Rico, which the Pentagon approved. The observatory, located near the equator, offers a clear view of the solar system. It features a massive reflector made of adjustable aluminum panels and is operated by Cornell University and the National Science Foundation. Researchers study pulsars, planets, and search for extraterrestrial life. The facility is accessible via an aerial tramway, providing a unique scientific environment.
