Messaging To Extra-Terrestrial Intelligence
Active SETI (Active Search for Extra-Terrestrial Intelligence) is the attempt to send messages to intelligent extraterrestrial life. Active SETI messages are predominantly sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message. Active SETI is also known as METI (Messaging to Extra-Terrestrial Intelligence). The term METI was coined by Russian scientist Alexander Zaitsev, who proposed a subtle distinction between Active SETI and METI: In 2010, Douglas A. Vakoch from SETI Institute, addressed concerns about the validity of Active SETI alone as an experimental science by proposing the integration of Active SETI and Passive SETI programs to engage in a clearly articulated, ongoing, and evolving set of experiments to test various versions of the Zoo Hypothesis, including specific dates at which a first response to messages sent to particular stars could be expected. On 13 February 2015, scientists (includi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arecibo Message Bw
Arecibo (; ) is a city and municipality on the northern coast of Puerto Rico, on the shores of the Atlantic Ocean, located north of Utuado and Ciales; east of Hatillo; and west of Barceloneta and Florida. It is about west of San Juan, the capital city. Arecibo is the largest municipality in Puerto Rico by area, and it is the core city of the Arecibo Metropolitan Statistical Area and part of the greater San Juan Combined Statistical Area.

A Simple Response To An Elemental Message
A Simple Response to an Elemental Message (ASREM) was an Interstellar Radio Message (IRM) consisting primarily of 3775 worldwide responses to this initiative's posed question; "''How will our present, environmental interactions shape the future?''" This transmission also features a smaller 'Honorary Mention' text archive and a series of images of Earth. This interstellar "message in a bottle" was transmitted on 10 October 2016, at 20:00 UTC by the European Space Agency Cebreros (DSA2) deep-space tracking station towards Polaris; the Pole Star which is approximately 434 light years (133 parsecs) from Earth. The IRM consisted of a single 27,653,733 byte, 866 second transmission. As of , the signal has traveled approximately . Concept and plan overview The non-for-profit ASREM initiative was devised and produced by artist Paul Quast in collaboration with the UK Astronomy Technology Centre, European Space Agency and the University of Edinburgh along with researchers working at the ...

Wow! Signal
The Wow! signal was a strong narrowband radio signal detected on August 15, 1977, by Ohio State University's Big Ear radio telescope in the United States, then used to support the search for extraterrestrial intelligence. The signal appeared to come from the direction of the constellation Sagittarius and bore the expected hallmarks of extraterrestrial origin. Astronomer Jerry R. Ehman discovered the anomaly a few days later while reviewing the recorded data. He was so impressed by the result that he circled on the computer printout the reading of the signal's intensity, "6EQUJ5", and wrote the comment "Wow!" beside it, leading to the event's widely used name. The entire signal sequence lasted for the full 72-second window during which Big Ear was able to observe it, but has not been detected since, despite several subsequent attempts by Ehman and others. Many hypotheses have been advanced on the origin of the emission, including natural and human-made sources, but none of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Across The Universe (message)
Across the Universe is an interstellar radio message (IRM) consisting of the song "Across the Universe" by the Beatles that was transmitted on 4 February 2008, at 00:00 UTC by NASA in the direction of the star Polaris. This transmission was made using a 70-meter dish in the NASA Deep Space Network's (DSN) Madrid Deep Space Communication Complex, located in Robledo, near Madrid, Spain. This action was done in order to celebrate the 40th anniversary of the song's recording, the 45th anniversary of the DSN, and the 50th anniversary of NASA. The idea was hatched by Beatles historian Martin Lewis, who encouraged all Beatles fans to play the track as it was beamed towards the distant star. The event marked the second time a song had ever been intentionally transmitted into deep space (the first being Russia's Teen Age Message in 2001), and was approved by Paul McCartney, Yoko Ono, and Apple Records.

Teen Age Message
The Teen Age Message (TAM) was a series of interstellar radio transmissions sent from the Yevpatoria Planetary Radar to six solar-type stars during August–September 2001. The structure of the TAM was suggested by Alexander Zaitsev, Chief Scientist at Russia's Institute of Radio-engineering and Electronics. The message's content and target stars were selected by a group of teens from four Russian cities, who collaborated in person and via the Internet. Each transmission comprised three sections: a sounding, a live theremin concert, and digital data including images and text. TAM was humanity's fourth Active SETI broadcast and the first musical interstellar radio message. Overview Zaitsev's proposal for a musical message – the "First Theremin Concert for Extraterrestrials" – was submitted to the Arecibo Observatory in July 2000. It was rejected amid concerns over the dangers posed by advertising the presence of humanity to unknown and possibly highly advanced civilizations. ...

The Morse Message (1962)
The Morse Message was a series of brief radio messages in Morse code that were transmitted from the Evpatoria Planetary Radar (EPR) complex and directed to the planet Venus in 1962. The message consisted of three words, all encoded in Morse code: the word “Mir” (russian: “Мир”, meaning both “peace” and “world”) was transmitted from the EPR on November 19, 1962, and the words “Lenin” (russian: “Ленин”) and “USSR” (russian: “СССР”, the abbreviation for the Soviet Union — russian: Сою́з Сове́тских Социалисти́ческих Респу́блик, ''Soyúz Soviétskikh Sotsialistícheskikh Respúblik'') were transmitted on November 24, 1962. In Russian, the Morse Message is referred to as the Radio Message “MIR, LENIN, USSR”. The message was the first radio broadcast intended for extraterrestrial civilizations in the history of mankind. It was also used to test the radar station (though not for measuring the dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Globular Cluster M13
Messier 13 or M13, also designated NGC 6205 and sometimes called the Great Globular Cluster in Hercules or the Hercules Globular Cluster, is a globular cluster of several hundred thousand stars in the constellation of Hercules. Discovery and visibility M13 was discovered by Edmond Halley in 1714, and cataloged by Charles Messier on June 1, 1764, into his list of objects not to mistake for comets; Messier's list, including Messier 13, eventually became known as the Messier Catalog. About one third of the way from Vega to Arcturus, four bright stars in Herculēs form the Keystone asterism, the broad torso of the hero. M13 can be seen in this asterism of the way north ( by west) from Zeta to Eta Herculis. Although only telescopes with great light-gathering capability fully resolve the stars of the cluster, M13 may be visible to the naked eye depending on circumstances. With a low-power telescope, Messier 13 looks like a comet or fuzzy patch. The cluster is visible throughout the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arecibo Message
The Arecibo message is an interstellar radio message carrying basic information about humanity and Earth that was sent to the globular cluster Messier 13 in 1974. It was meant as a demonstration of human technological achievement, rather than a real attempt to enter into a conversation with extraterrestrials. It has been noted that the low resolution of the image makes it infeasible for any extraterrestrial recipients to attach the intended meaning to most of its elements. The message was Broadcasting, broadcast into space a single time via frequency modulation, frequency modulated radio waves at a ceremony to mark the remodeling of the Arecibo Telescope in Puerto Rico on 16 November 1974. The message was aimed at the current location of M13, about 25,000 light years from Earth, because M13 was a large and relatively close collection of stars that was available in the sky at the time and place of the ceremony. When correctly translated into graphics, characters, and spaces, the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frequency-shift Keying
Frequency-shift keying (FSK) is a frequency modulation scheme in which digital information is transmitted through discrete frequency changes of a carrier signal. The technology is used for communication systems such as telemetry, weather balloon radiosondes, caller ID, garage door openers, and low frequency radio transmission in the VLF and ELF bands. The simplest FSK is binary FSK (BFSK). BFSK uses a pair of discrete frequencies to transmit binary (0s and 1s) information. With this scheme, the 1 is called the mark frequency and the 0 is called the space frequency. Modulating and demodulating Reference implementations of FSK modems exist and are documented in detail. The demodulation of a binary FSK signal can be done using the Goertzel algorithm very efficiently, even on low-power microcontrollers. Variations Multiple frequency-shift keying Continuous-phase frequency-shift keying In principle FSK can be implemented by using completely independent free-running oscillat ...

Arecibo Observatory
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). The observatory's main instrument was the Arecibo Telescope, a spherical reflector dish built into a natural sinkhole, with a cable-mount steerable receiver and several radar transmitters for emitting signals mounted above the dish. Completed in 1963, it was the world's largest single-aperture telescope for 53 years, surpassed in July 2016 by the Five-hundred-meter Aperture Spherical Telescope (FAST) in China. Following two breaks in cables supporting the receiver platform in mid-2020, the NSF decommissioned the telescope. A partial collapse of the telescope occurred on December 1, 2020, before controlled demolition could be conducted. In 2022, the NSF announced the telescope will not be rebuilt, with an educational fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
