The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC), operated in Barrio Esperanza, Arecibo, Puerto Rico and was owned by the US National Science Foundation. Completed in 1963, it held the position of world's largest telescope until 2016. Since the beginning of its operation, the Arecibo Observatory has been an integral piece in many scientific breakthroughs including the first discovery of a binary pulsar, the first discovery of an extrasolar planet, the composition of the ionosphere, and the characterization of the properties and orbits of a myriad of potentially hazardous asteroids.


Arecibo Observation Data

After its decommission in 2020, the Arecibo Observatory coordinated with TACC to store and preserve the valuable data that had been accrued over more than half a century of astronomical observations. TACC is now hosting this data for access by researchers.
