Completed in 1963 and stewarded by U.S. National Science Foundation since the 1970s, Arecibo Observatory has contributed to many important scientific discoveries, including the demonstration of gravitational waves from a binary pulsar, the first discovery of an extrasolar planet, composition of the ionosphere, and the characterization of the properties and orbits of a number of potentially hazardous asteroids.
