In 2003, Radio source SHGb02 + 14a was isolated by SETI @ home analysis, although it has largely been discounted by further study.

SETI @ home was conceived by David Gedye along with Craig Kasnoff and is a popular volunteer distributed computing project that was launched by the University of California, Berkeley in May 1999.

Any individual can become involved with SETI research by downloading the Berkeley Open Infrastructure for Network Computing ( BOINC ) software program, attaching to the SETI @ home project, and allowing the program to run as a background process that uses idle computer power.

The SETI @ home program itself runs signal analysis on a " work unit " of data recorded from the central 2. 5 MHz wide band of the SERENDIP IV instrument.

After computation on the work unit is complete, the results are then automatically reported back to SETI @ home servers at UC Berkeley.

As of June 28, 2009 the SETI @ home project has over 180, 000 active participants volunteering a total of over 290, 000 computers.

These computers give SETI @ home an average computational power of 617 teraFLOPS.

As of 2010, after 10 years of data collection, SETI @ home has listened to that one frequency at every point of over 67 percent of the sky observable from Arecibo with a least 3 scans ( out of the goal of 9 scans ), which covers about 20 percent of the full celestial sphere.

Although other volunteering projects such as Zooniverse credit users for discoveries, there is currently no crediting or early notification by SETI @ Home following the discovery of a signal.

If a virus is detected, the window turns red and the scan is stopped, and the alert is shown once you exit the screensaver ) or a distributed computing application ( such as the SETI @ home project ).

The telescope received additional recognition in 1999 when it began to collect data for the SETI @ home project.

SETI @ home, the largest distributed computing experiment on Earth, is perhaps the Society's best-known SETI project.

The main active competition is the RoboRumble @ Home, a continuous league based on distributed computation in a similar way to SETI @ Home.

SETI @ home (" SETI at home ") is an Internet-based public volunteer computing project employing the BOINC software platform, hosted by the Space Sciences Laboratory, at the University of California, Berkeley, in the United States.

The two original goals of SETI @ home were:

The current BOINC environment, a development of the original SETI @ home, is providing support for many computationally intensive projects in a wide range of disciplines.

Cyclops was not built, but the report formed the basis of much SETI work that followed.

After field tests that lasted into 1982, Suitcase SETI was put into use in 1983 with the 26-meter Harvard / Smithsonian radio telescope at Harvard, Massachusetts.

Even 131, 000 channels weren't enough to search the sky in detail at a fast rate, so Suitcase SETI was followed in 1985 by Project " META ", for " Megachannel Extra-Terrestrial Assay ".

In 1978, the NASA SETI program was heavily criticized by Senator William Proxmire, and funding for SETI research was removed from the NASA budget by Congress in 1981, however, funding was restored in 1982, after Carl Sagan talked with Proxmire and convinced him of the program's value.

Project Argus was conceived as a continuation of the all-sky survey component of the late NASA SETI program ( the targeted search having been continued by the SETI Institute's Project Phoenix ).

In the SETI context, the name has been used for radio telescopes in fiction ( Arthur C. Clarke, " Imperial Earth "; Carl Sagan, " Contact "), was the name initially used for the NASA study ultimately known as " Cyclops ," and is the name given to an omnidirectional radio telescope design being developed at the Ohio State University.

In response, SETI advocates note, among other things, that the Drake Equation was never a hypothesis, and so never intended to be testable, nor to be " solved "; it was merely a clever representation of the agenda for the world's first scientific SETI meeting in 1961, and it serves as a tool in formulating testable hypotheses.

The concern over SETI was raised by the science journal Nature in an editorial in October 2006, which commented on a recent meeting of the International Academy of Astronautics SETI study group.

The most optimistic search project to date was Project Ozma, which was intended to " search for extraterrestrial intelligence " ( SETI ) by examining selected stars for indications of artificial radio signals.

Until his death in 1996, the Society was actively led by Sagan, who used his celebrity and political clout to influence the political climate of the time, including protecting SETI in 1981 from congressional cancellation.

A new strategy in the search for extraterrestrial intelligence ( SETI ) was proposed by American space scientist William I. McLaughlin in 1977.

The SETI Institute has also publicly denied that the candidate signal Radio source SHGb02 + 14a is of extraterrestrial origin though full details of the signal, such as its exact location have never been disclosed to the public.

The SETI Institute ’ s public outreach efforts include working with teachers and students in promoting science education and the teaching of evolution, working with NASA on exploration missions such as Kepler and SOFIA, and producing a weekly science program: Are We Alone?

David Morrison, director of SETI, CSI Fellow and Senior Scientist at NASA's Astrobiology Institute at Ames Research Center, says he receives 20 to 25 emails a week about the impending arrival of Nibiru: some frightened, others angry and naming him as part of the conspiracy to keep the truth of the impending apocalypse from the public, and still others asking whether or not they should kill themselves, their children or their pets.

SETI projects use scientific methods to search for intelligent life on other planets.

The OSU SETI program gained fame on August 15, 1977 when Jerry Ehman, a project volunteer, witnessed a startlingly strong signal received by the telescope.

In 2005, the IAA established the SETI: Post-Detection Science and Technology Taskgroup ( Chairman, Professor Paul Davies ) " to act as a Standing Committee to be available to be called on at any time to advise and consult on questions stemming from the discovery of a putative signal of extraterrestrial intelligent ( ETI ) origin.

Further, they note 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.

He serves on the Board of Trustees of the SETI Institute.

He later became a co-founder of the Archaeology, Astronautics and SETI Research Association ( AAS RA ), and designed the theme park Mystery Park in Interlaken, Switzerland, that first opened on 23 May 2003.

It is similar to the SETI @ Home client, in that it uses a distributed computing client running primarily on home user's computers to correlate georeferenced biological samples with environmental models of the Earth.

With NVIDIA's assistance, some BOINC-based projects ( e. g., SETI @ home, MilkyWay @ home ) now have applications that run on NVIDIA GPUs using CUDA.

Featured guests include Nobel laureates and top researchers on the topics of string theory, time travel, black holes, gene therapy, aging, space travel, artificial intelligence, and SETI.

Distributed computing projects such as SETI @ home or NAGAR and popular applications like Google Earth rely primarily on client-side operations.

* The SETI @ home project uses a sneakernet to overcome bandwidth limitations: data recorded by the radio telescope in Arecibo, Puerto Rico is stored on magnetic tapes which are then shipped to Berkeley, California for processing.

The Mars Institute and SETI operate the Haughton-Mars Project at this site, designed to test many of the challenges of life and work on Mars.

Radio source SHGb02 + 14a is a source and a candidate in the Search for Extra-Terrestrial Intelligence ( SETI ), discovered in March 2003 by SETI @ home and announced in New Scientist on September 1, 2004.
