SETI SETI The Allen Telescope Array (ATA), formerly known as the One Hectare Telescope (1hT), is a joint effort by the SETI Institute and the Radio Astronomy Laboratory at the University of California, Berkeley to construct a radio interferometer that will be dedicated to astronomical and simultaneous search for extra-terrestrial intelligence observations. It is being constructed at the Hat Creek Radio Observatory, 290 miles northeast of San Francisco, California and will be composed of 350 antennas at completion. ...more on Wikipedia about "Allen Telescope Array"
Are We Alone? is the SETI Institute's weekly science radio program, hosted by Senior Astronomer Seth Shostak. The show covers a broad range of topics in the sciences, especially as they relate to our understanding of what life elsewhere in the universe might be like. Each week's show focuses on a particular topic and allows and scientists on the cutting-edge of research to share their latest findings; speculate on the implications for SETI and society in general, and answer questions from curious or puzzled callers. ...more on Wikipedia about "Are We Alone?"
The Arecibo message is a radio message that was beamed into space at a ceremony to mark the remodeling of the Arecibo radio telescope in 1974. It was aimed at the globular star cluster M13 some 25,000 light years away and consisted of 1679 binary digits. The number 1679 was chosen because it is the product of two prime numbers and therefore can only be broken down into 23 rows and 73 columns, or 73 rows and 23 columns. This assumes that those who read it will choose to arrange it as a quadrilateral. The information arranged the first way (23 rows, 73 columns) produces white noise, but if arranged the second way (73 rows, 23 columns) it forms the image shown on the right, which is assumed to be recognizable as data. Reading from right to left, it shows the numbers one through ten, the atomic numbers of hydrogen, carbon, nitrogen, oxygen, and phosphorus, the formulas for the sugars and bases in the nucleotides of DNA, the number of nucleotides in DNA, the double helix structure of DNA, a figure of a human being and its height, the population of Earth, our solar system, and an image of the Arecibo telescope with its diameter. ...more on Wikipedia about "Arecibo message"
The Arecibo Observatory is located approximately 12 miles south-southwest from Arecibo, Puerto Rico (near the extreme southwestern corner of Arecibo municipio). It is operated by Cornell University under cooperative agreement with the National Science Foundation. The observatory works as the National Astronomy and Ionosphere Center (NAIC) although both names are officially used to refer to it. ...more on Wikipedia about "Arecibo Observatory"
Sir Arthur Charles Clarke (born December 16 1917) is a British author and inventor, most famous for his science-fiction novel 2001: A Space Odyssey, and for collaborating with director Stanley Kubrick on the film of the same name. Clarke is considered one of the Big Three of science fiction, along with Robert A. Heinlein and Isaac Asimov. ...more on Wikipedia about "Arthur C. Clarke"
Astrosociobiology (also referred to as exosociobiology and xenosociology) is the speculative scientific study of extraterrestrial civilizations and their possible social characteristics and developmental tendencies. The field involves the convergence of astrobiology, sociobiology and evolutionary biology. Hypothesized comparisons between human civilizations and those of extraterrestrials are frequently posited, placing the human situation in the same context as other extraterrestrial intelligences. Whenever possible, astrosociobiologists describe only those social characteristics that are thought to be common (or highly probable) to all civilizations. Thus far, it is entirely theoretical. ...more on Wikipedia about "Astrosociobiology"
A Bracewell probe is a hypothetical concept for an autonomous interstellar space probe dispatched for the express purpose of communication with one or more alien civilizations. It was proposed by Ronald N. Bracewell in a 1960 paper, as an alternative to interstellar radio communication between widely separated civilizations. ...more on Wikipedia about "Bracewell probe"
CETI (Communication with Extraterrestrial Intelligence, or more correctly METI, Messaging to Extraterrestrial Intelligence) is a branch of SETI research that focuses on composing and deciphering messages that could theoretically be understood by another technological civilization. The best known CETI experiment was the 1974 Arecibo message composed by Frank Drake and Carl Sagan. ...more on Wikipedia about "Communication with Extraterrestrial Intelligence"
CosmicOS is a self-contained message designed to be understood primarily by treating it as a computer program and executing it. It is inspired by Hans Freudenthal's Lincos. ...more on Wikipedia about "CosmicOS"
David P. Anderson is currently a Research Scientist at the Space Sciences Laboratory, at the University of California, Berkeley. Dr. Anderson leads the SETI@home and BOINC projects. SETI@home is a large distributed computing project, and BOINC is an open-source software system for creating such projects. ...more on Wikipedia about "David P. Anderson"
The Drake equation (also known as the Green Bank equation or the Sagan equation) is a famous result in the speculative fields of xenobiology, astrosociobiology and the search for extraterrestrial intelligence. ...more on Wikipedia about "Drake equation"
A Dyson sphere (or "shell" as it appeared in the original paper) is a hypothetical megastructure. It was originally described as a system of orbiting solar power satellites meant to completely englobe a star and capture its entire energy output, although other variants on this idea have been proposed — most notedly the solid shell concept pictured at right. The Dyson sphere concept was first mentioned in the novel Star Maker, by Olaf Stapledon, and formally described by physicist Freeman Dyson in his 1959 paper "Search for Artificial Stellar Sources of Infra-Red Radiation", published in the journal Science. While building a Dyson sphere is far beyond present-day industrial capabilities, some proposed design variants of the sphere do not require technology much in advance of our own. ...more on Wikipedia about "Dyson sphere"

Dr. Laurance R. Doyle is a scientist who received his PhD from the Ruprecht Karl University of Heidelberg. He has worked for SETI since 1987 and is a principle investigator for them. His main area of study has been the formation and detection of extrasolar planets ** , but he has also worked on communications theory. In particular he has written on how patterns in animal communication relate to humans with an emphasis on cetaceans. ...more on Wikipedia about "Laurance Doyle"

SETI is an acronym for the Search for Extra-Terrestrial Intelligence. Support for the original SETI@home client (known as SETI Classic) was ended on December 15, 2005. SETI@home continues with the newer client on the BOINC platform. ...more on Wikipedia about "SETI@home"
The Wow! signal was a strong narrowband radio signal detected by the astrophysicist Jerry R. Ehman on August 15, 1977 while working on a SETI project at the Big Ear radio telescope of Ohio State University. The signal bore expected earmarks of potential non- terrestrial and non- solar system origin. It lasted for 72 seconds and has not been detected thereafter. All subsequent searches for a signal in the same location have been unsuccessful, both by J. R. Ehman and others. The nature of the signal is therefore unknown and only a few possibilities can be considered. ...more on Wikipedia about "Wow! signal"
