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.

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.

SETI @ home was released to the public on May 17, 1999, making it the second large-scale use of distributed computing over the Internet for research purposes, as Distributed. net was launched in 1997.

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.

Later, it began the world's first continuous SETI program, called the Ohio State University SETI program.

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 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.

In 1992, the U. S. government funded an operational SETI program, in the form of the NASA Microwave Observing Program ( MOP ).

SETI advocates continued without government funding, and in 1995 the nonprofit SETI Institute of Mountain View, California resurrected the MOP program under the name of Project " Phoenix ", backed by private sources of funding.

Founded in 1994 in response to the US Congress cancellation of the NASA SETI program, The SETI League, Inc. is a membership-supported nonprofit organization with 1, 500 members in 62 countries.

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 ).

The SETI program began with Paul Horowitz ’ s Suitcase SETI and has grown to encompass searches in radio and optical wavelengths from the northern and southern hemispheres of the Earth.

Anybody with an at least intermittently Internet-connected computer can participate in SETI @ home by running a free program that downloads and analyzes radio telescope data.

These activities provide approximately 40 hours of space journeys and astronomical lessons, to include extensive tours of the Celestia universe, the complete life cycle of stars, the solar system, the human space program, the Search for Extraterrestrial Intelligence ( SETI ), and depictions of astronomical events such as the formation of our moon billions of years ago, and the possible terraforming of Mars in the future.

The 21 cm hydrogen line is considered a favorable frequency by the SETI program in their search for signals from potential extraterrestrial civilizations.

According to George Basalla, the paper by Cocconi and Morrison " provided a reasonable theoretical basis " for the then nascent SETI program.

Einstein @ Home runs through the same software platform as SETI @ home, the Berkeley Open Infrastructure for Network Computing ( BOINC ).

* 1977 – The Big Ear, a radio telescope operated by Ohio State University as part of the SETI project, receives a radio signal from deep space ; the event is named the " Wow!

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.

The current protocol for SETI Institute is to first internally investigate the signal, seeking independent verification and confirmation.

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.

SETI @ home has denied media reports of a likely extraterrestrial intelligence signal.

* Project Phoenix ( SETI ) or Phoenix Project, a search for extraterrestrial intelligence in radio signal patterns

signal was a strong narrowband radio signal detected by Jerry R. Ehman on August 15, 1977, while working on a SETI project at the Big Ear radio telescope of The Ohio State University then located at Ohio Wesleyan University's Perkins Observatory, Delaware, Ohio.

The frequency 1420 MHz is significant for SETI searchers because, it is reasoned, hydrogen is the most common element in the universe, and hydrogen resonates at about 1420 MHz, thus extraterrestrials might use that frequency on which to transmit a strong signal.

In a July 1995 test of signal detection software to be used in its upcoming Project Argus search, SETI League executive director H. Paul Shuch made several drift-scan observations of the ' Wow!

* Quasar CTA-102, which was believed by Dr. Nikolai S. Kardashev to have an extraterrestrial signal encoded in it before further examination proved it to be a quasar, the first widely reported work of SETI activity.

It was here that a part The Arrival ( 1996 ) movie was film, being it the place where Zane Zaminsky ( Charlie Sheen ) and Calvin ( Richard Schiff ) work for SETI and discover the alien signal, later in the movie one of the Radio Antennas is destroyed by a BHB ( Black Hole Bomb ) to prevent Zane from escaping a tape containing the proof of the aliens terraforming the earth and the assassinations of Calvin and Ilana Green ( Lindsay Crouse ).
