SETI advocates did not give up, and in 1995 the nonprofit "SETI Institute" of Mountain View, California, resurrected the work under the name of Project "Phoenix", backed by private sources of funding.
While most SETI sky searches have studied the radio spectrum, some SETI researchers have considered the possibility that alien civilizations might be using powerful lasers for interstellar communications at optical wavelengths.
While many of the arguments against SETI are themselves pseudoscience of the best sort, describable, charitably, as metaphysics at best, there is a line of attack on SETI which has credibility and has yet to be adequately answered in the opinions of many scientists.

A basic assumption of SETI is the assumption of "Mediocrity"[1]: the idea that humanity is not exotic in the Cosmos but in a sense "typical" or "medium" when compared with other intelligent species.
SETI has occasionally been the target of criticism by those who suggest that it is a form of pseudoscience.
In response, SETI advocates note, among other things, that the existence of intelligent life on Earth is a plausible reason to expect it elsewhere, and that individual SETI projects have clearly defined "stop" conditions.

 SETI@home - Wikipedia, the free encyclopedia
SETI@home ("SETI at home") is a grid computing (distributed computing in the project's own terminology) project using Internet-connected computers, hosted by the Space Sciences Laboratory, at the University of California, Berkeley, in the United States.
Seth Shostak (2004), a prominent SETI figure, has stated that he expects to get a conclusive signal and proof of alien contact between 2020 and 2025, based on the Drake equation.
Other users collected large quantities of equipment together at home to create "SETI farms", which typically consist of a number of computers consisting of only a motherboard, CPU, RAM and power supply that are arranged on shelves as diskless workstations running either Linux or Windows 98 SE "headless" (without a video card).

Some SETI observations have been conducted using the 305m radio telescope at the Arecibo Observatory in Puerto Rico.
The generic approach of SETI projects is to survey the sky to detect the existence of transmissions from a civilization on a distant planet.
Concerning the latter argument, it should be noted that the justification for SETI projects doesn't necessarily require an acceptance of the Drake equation.

 OS: Preface
SETI consists entirely of a simple search for electromagnetic signals of a certain type that the SETI scientists expect to be used by extraterrestrial intelligence (ETI).
SETI scientists explain that the signals they seek will be very difficult to find, if they exist at all, and that it is necessary to be steadfast and continue the search, indefinitely, almost as a permanent fixture of society.
It should be understood that SETI, the program, is a response to a need that is as transcendental as any human quest can be, for it is intimately concerned with the cosmological setting in which the human race had its origins.

 SETI and the Amateur Radio Astronomer
SETI hypothesizes that other technological civilizations are similarly surrounded by a detectable sphere of microwave radiation, the radius of which will be limited only by the length of time such civilizations have possessed sufficiently advanced radio technology.
SETI League members have developed a variety of shareware FFT programs to sort this audio output into bins, and display the results on the computer monitor as histograms, waterfall displays, or any number of alternative formats.
A major concern of SETI professionals is whether amateur radio astronomers have the training and discipline to separate the electromagnetic wheat from the cosmic chaff.

 The Search for Extraterrestrial Intelligence   (Site not responding. Last check: 2007-11-01)
SETI (Search for Extraterrestrial Intelligence) is an attempt to detect technological civilizations elsewhere in the universe, particularly in our galaxy.
Since the H and OH lines are visible throughout the universe, in the quietest part of the radio spectrum, it would be a logical band for other civilizations to choose to send out a signal.
The SETI Institute and the University of California, Berkeley, recently signed a memorandum of understanding that could result in the construction of a world-class telescope array that would be an order of magnitude less expensive than comparably sized, contemporary instruments.

 SETI: Interesting Thing of the Day
SETI is a cooperative effort by a great many astronomers, engineers, mathematicians, and other scientists to find evidence of the existence of intelligent life in outer space.
So what SETI is really listening for right now is signals far more powerful than we ourselves could generate—or, and this is a long shot to say the least, a directional signal aimed straight at Earth.
If SETI operated for centuries, it would only be able to listen to the tiniest portion of the observable universe, and even then, a lack of evidence would not be the same as proof of the nonexistence of intelligent life beyond our planet.

 Introduction to the COSETI Web Site
The optical approach to SETI using continuous wave laser beacons was first proposed by Schwartz and Townes in 1961, one year after the laser was invented and two years after Cocconi and Morrison proposed the microwave approach to SETI.
Unfortunately, the optical approach to SETI, for reasons that are described herein and which are largely due to the Project Cyclops Report, has suffered over 25 years of neglect, particularly in the United States.
The SETI Institute and The Planetary Society now consider Optical SETI to be a viable approach, with the major activity being directed at detecting pulsed laser beacons.

 About SETI@home
SETI (Search for Extraterrestrial Intelligence) is a scientific area whose goal is to detect intelligent life outside Earth.
Previous radio SETI projects have used special-purpose supercomputers, located at the telescope, to do the bulk of the data analysis.
In addition to SETI, he studies interstellar matter (the gas and dust that lies between the stars) using radio, optical, and space-based ultraviolet telescopes.

 Seti, Seti Project, What Is Seti at SPACE.com
The acronym SETI stands for the Search for Extra-Terrestrial Intelligence, a theme common in many fictional works of film and literature, but has recently gained more realistic applications.
Because we are not able to physically visit the 100,000 light years of space in our galaxy, SETI projects rely on searching for transmissions from the other civilizations.
SETI researchers are also unsure how to receive the messages, as the modulation these life forms might be using remains a mystery.

 Universe Today - Dr. Seth Shostak Answers Your Questions About SETI
This is rather surprising, because the history of astronomy suggests that whenever you build a new instrument, able to look at a previously unobserved bit of either space or the spectrum, you usually trip across some unexpected object or other.
This is a straightforward SETI experiment that will scrutinize lots of stars, albeit stars that are (on average) thousands of light-years away.
Well, there's no secrecy in SETI, and it's been our experience that whenever we pick up an "interesting" signal, the media are on top of the story right away.

 Life Beyond Earth - SETI
SETI is an effort to locate evidence of past or present communicative civilizations in the universe, particularly within our own galaxy.
The idea of searching for extraterrestrial life has been dreamed of through the ages, but the spark behind contemporary methodology began in 1959 when two physicists from Cornell asserted that microwave radio waves could be used for interstellar communication.
It continued until the early 1990s, when SETI funding was cut after being ridiculed on the floor of Congress as a search for "little green men." Since then, the SETI Institute, a non-profit corporation, has taken over the search, as have several other privately-funded SETI projects.

 Harvard SETI Group Searches
Suitcase SETI travelled to Arecibo in March 1982, where it searched 250 candidates (stellar and other), mostly at the second harmonic of HI, at 2.84 GHz.
Sentinel and its predecessors achieved high resolution at the expense of total frequency coverage (2 kHz for Suitcase SETI and Sentinel, 1 kHz for the earlier off-line search), which required a transmitting civilization to target our star specifically, in order to permit Doppler precompensation to the heliocentric frame.
META was the first megachannel SETI, and ran for a decade before being replaced by BETA in 1995.

There is a sense of wanting to help: the Seti project is not funded by the authorities and we would like to support it.
I believe that a very similar gut- level feeling makes us participate in the Seti project: we are contributing to human knowledge; the beneficiary is the human kind; and as such it is a morally worthy enterprise.
Hence the reason why I consider it worthwhile to reflect on the success of the Seti project, before some sociologist (or a media-specialist) ends up reducing this into a 'phenomenon' much like a successful film (or a fad).

In a nutshell, the project's goal is to allow the SETI folks at Arecibo to sweep their visible region of sky three times in the next two years, and distribute the radio signals they receive to the public (those of us running the SETI client) in 340-350KB chunks (a.k.a.
If an admin ever encounters a situation where the client needs to be stopped, he or she can simply send out "net stop seti" to the intended machine(s).
