Where was the CETI created by Frank Drake and Carl Sagan in 1974 sent?
Arecibo message The Arecibo message is a 1974 interstellar radio message carrying basic information about humanity and Earth sent to globular star cluster M13 in the hope that extraterrestrial intelligence might receive and decipher it. The message was broadcast into space a single time via frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo radio telescope in Puerto Rico on 16 November 1974. The message was aimed at the current location of M13 some 25,000 light years away because M13 was a large and close collection of stars that was available in the sky at the time and place of the ceremony. The message consisted of 1,679 binary digits, approximately 210 bytes, transmitted at a frequency of 2,380 MHz and modulated by shifting the frequency by 10 Hz, with a power of 1,000 kW. The "ones" and "zeros" were transmitted by frequency shifting at the rate of 10 bits per second. The total broadcast was less than three minutes.
Imperial Earth Imperial Earth is a science fiction novel by British writer Arthur C. Clarke, published in time for the U.S. bicentennial in 1976 by Ballantine Books. The plot follows the protagonist, Duncan Makenzie, on a trip to Earth from his home on Titan, ostensibly for a diplomatic visit to the U.S. for its 500th birthday, but really in order to have a clone of himself produced.
