The Arecibo Observatory, also known as the National Astronomy and Ionosphere Center (NAIC) and formerly known as the Arecibo Ionosphere Observatory, is an observatory in Barrio Esperanza, Arecibo, Puerto Rico owned by the US National Science Foundation (NSF).[1]
In November 16, 1974 SETI sent out a transmission to space detailing human DNA, location and other information in hopes of reaching alien civilization from Arecibo. In January 1993 they received a message back. First message was for a superior catalyst for methane, the second one for DNA combining.[2]
