Where was the CETI created by Frank Drake and Carl Sagan in 1974 sent?
Communication with extraterrestrial intelligence Communication with extraterrestrial intelligence (a.k.a CETI) is a branch of the search for extraterrestrial intelligence that focuses on composing and deciphering interstellar messages that theoretically, could be understood by another technological civilization. This field of study once was known as "exosemiotics". The best-known CETI experiment of its kind was the 1974 Arecibo message composed by Frank Drake and Carl Sagan. There are multiple independent organizations and individuals engaged in CETI research; the generic application here of abbreviations CETI and SETI (search for extraterrestrial intelligence) should not be taken as referring to any particular organization (such as the SETI Institute).
Nation of Celestial Space The Nation of Celestial Space (also known as Celestia) was a micronation created by Evergreen Park, Illinois, resident James Thomas Mangan. Celestia comprised the entirety of "outer space", which Mangan laid claim to on behalf of humanity to ensure that no one country might establish a political hegemony there. As "Founder and First Representative", he registered this acquisition with the Recorder of Deeds and Titles of Cook County on January 1, 1949. At its foundation Celestia claimed to have 19 members, among them Mangan's daughter Ruth; a decade later a booklet published by the group claimed that membership had grown to 19,057.
