Arecibo Observatory

Arecibo Observatory Review

Hidden among pine-covered hills, the Arecibo Observatory is home to the world's largest radar-radio telescope. Operated by the National Astronomy and Ionosphere Center of Cornell University, the 20-acre dish lies in a 563-foot-deep sinkhole in the karst landscape. If the 600-ton platform hovering eerily over the dish looks familiar, it may be because it was featured in the movie Contact. You can walk around the viewing platform and explore two levels of interactive exhibits on planetary systems, meteors and weather phenomena in the visitor center. There's also a gift shop. Note that the trail leading up to the observatory is extremely steep. For those who have difficulty walking or have a medical condition, ask a staff member at the gate about a van that provides courtesy shuttle service to the observatory entrance.
