The Arecibo Observatory is a radio telescope in the municipality of Arecibo, Puerto Rico. This observatory is operated by University of Central Florida, Yang Enterprises and UMET, under cooperative agreement with the National Science Foundation (NSF).[1][2] The observatory is the sole facility of the National Astronomy and Ionosphere Center (NAIC), which is the formal name of the observatory.[3] From its construction in the 1960s until 2011, the observatory was managed by Cornell University.

The observatory's 305-m radio telescope is the largest single-aperture telescope (cf. multiple aperture telescope) ever constructed.

Arecibo message Edit

In 1974, the Arecibo message, an attempt to communicate with potential extraterrestrial life, was transmitted from the radio telescope toward the globular cluster Messier 13, about 25,000 light-years away.[4] The 1,679 bit pattern of 1s and 0s defined a 23 by 73 pixel bitmap image that included numbers, stick figures, chemical formulas and a crude image of the telescope.[5]
