Question: Where was the CETI created by Frank Drake and Carl Sagan in 1974 sent?
Context: Cosmos: A Spacetime Odyssey is a 2014 American science documentary television series.  The show is a follow-up to the 1980 television series "", which was presented by Carl Sagan on the Public Broadcasting Service and is considered a milestone for scientific documentaries.  This series was developed to bring back the foundation of science to network television at the height of other scientific-based television series and films.  The show is presented by astrophysicist Neil deGrasse Tyson, who, as a young high school student, was inspired by Sagan.  Among the executive producers are Seth MacFarlane, whose financial investment was instrumental in bringing the show to broadcast television, and Ann Druyan, a co-author and co-creator of the original television series and Sagan's wife.  The show is produced by Brannon Braga, and Alan Silvestri composed the backing score. Cosmos is a 1980 popular science book by astronomer and Pulitzer Prize-winning author Carl Sagan.  Its 13 illustrated chapters, corresponding to the 13 episodes of the , which the book was co-developed with and intended to complement, explore the mutual development of science and civilization.  One of Sagan's main purposes for the book and television series was to explain complex scientific ideas to anyone interested in learning.  Sagan also believed the television was one of the greatest teaching tools ever invented, so he wished to capitalize on his chance to educate the world.  Spurred in part by the popularity of the TV series, "Cosmos" spent 50 weeks on the "Publishers Weekly" best-sellers list and 70 weeks on the "New York Times" Best Seller list to become the best-selling science book ever published at the time.  In 1981, it received the Hugo Award for Best Non-Fiction Book.  The book's unprecedented success ushered in a dramatic increase in visibility for science-themed literature.  The success of the book also jumpstarted Sagan's literary career.  The sequel to "Cosmos" is "Pale Blue Dot: A Vision of the Human Future in Space" (1994). 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). "Visions of the 21st Century" is a speech delivered by Carl Sagan at the fiftieth anniversary celebration of the United Nations on October 24, 1995 (United Nations Day) in New York in the Cathedral of St. John the Divine.  In the introduction, Sagan discusses the human unity that is present in the world despite its vast human diversity.  He points out that we as humans are all cousins that can be traced back through human ancestry in east Africa.  The theme of Sagan's speech promoted the importance of fostering a Global Community.  This theme of Visions of the 21st Century represents the overarching theme of the U.N.'s fiftieth anniversary celebration which was "We The Peoples of the United Nations...United for a Better World".  He stresses the importance of maintaining a healthy Global Environment, as changes in the global environment are a common threat to all of humanity.  The change in the Global Environment he focuses on is climate change.  He also elaborates on the great power that modern technology allows each to nation to possess.  He praises the advances in medical technology of the world particularly.  Yet, Sagan warns that the mix of technological power and ignorance has the potential to lead to disaster.  Thus, this enormous power must be guarded against misuse.  To do this, Sagan suggests that widespread knowledge of science and technology is beneficial.  Sagan discusses the minuscule presence of the Earth within the vast scale of the cosmos, and how it is a delusion to believe we as humans are somehow elite in the universe.  Sagan implores humanity to protect and cherish this earth that we know, as it is solely the responsibility of humanity alone. Contact is a 1985 hard science fiction novel by American scientist Carl Sagan.  It deals with the theme of contact between humanity and a more technologically advanced, extraterrestrial life form.  It ranked No. 7 on the 1985 U.S. bestseller list.  The novel originated as a screenplay by Sagan and Ann Druyan (whom he later married) in 1979; when development of the film stalled, Sagan decided to convert the stalled film into a novel.  The film concept was subsequently revived and eventually released in 1997 as the film "Contact" starring Jodie Foster. Steven W. Squyres (born January 9, 1956) is the James A. Weeks Professor of Physical Sciences at Cornell University in Ithaca, New York.  His research area is in planetary sciences, with a focus on large solid bodies in the Solar System such as the terrestrial planets and the moons of the Jovian planets.  Squyres is principal investigator of the Mars Exploration Rover Mission (MER).  He is the recipient of the 2004 Carl Sagan Memorial Award and the 2009 Carl Sagan Medal for Excellence in Communication in Planetary Science.  On October 28, 2010, Dr. Squyres received the 2010 Mines Medal for his achievements as a researcher and professor.  He is the brother of Academy Award-nominated film editor Tim Squyres. The Cosmic Connection: An Extraterrestrial Perspective is a book by Carl Sagan, produced by Jerome Agel.  It was originally published in 1973; an expanded edition with contributions from Freeman Dyson, David Morrison, and Ann Druyan was published in 2000 under the title "Carl Sagan's Cosmic Connection".  The book contains artwork by Jon Lomberg and other artists. The Carl Sagan Memorial Award is an award presented jointly by the American Astronautical Society and The Planetary Society to an individual or group "who has demonstrated leadership in research or policies advancing exploration of the Cosmos."  The annual award, first presented in 1997, was created in honor of American astronomer, astrobiologist and science popularizer, Carl Sagan (1934–1996). The Voyager Golden Record contains 115 images plus a calibration image and a variety of natural sounds, such as those made by surf, wind, and thunder, and animal sounds, including the songs of birds and whales.  The record additionally features musical selections from different cultures and eras, spoken greetings in fifty-nine languages, other human sounds, like footsteps and laughter (Carl Sagan's ), and printed messages from President Jimmy Carter and U.N. Secretary-General Kurt Waldheim.  The items were selected for NASA by a committee chaired by Carl Sagan of Cornell University. 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.
Answer: sent to globular star cluster M13
