The search for radio signals from beings on other worlds reaches its half century this April.
SETI
SETI is an acronym for the Search for ExtraTerrestrial Intelligence.
SETI is still no trivial task. Our Galaxy is 100,000 light-years across, and contains 100,000 thousand million stars. Searching the entire sky for some faraway and faint signal is an exhausting exercise.
Search for Extraterrestrial Intelligence (SETI)
An exploratory science that searches for evidence of life in the universe.

SETI
The Search for Extraterrestrial Intelligence. This is a "passive" search in that we are listening for signals. This does not presently involve the "active" means of transmitting, be it in the microwave or optical regime.
SETI
The Search for Extraterrestrial Intelligence, by using radiotelescopes to listen for signals transmitted by intelligent alien beings.

SETI is an acronym for "Search for ExtraTerrestrial Intelligence." It is an ongoing project in which are searching the sky for signs of intelligent life elsewhere in our galaxy.
Recently, SETI institute astronomer, Peter Jenniskens, has suggested that the Quadrantids are tied to the near-Earth asteroid 2003EH1. Dr Jenniskens believes this object is actually an extinct comet, possibly once seen by the Chinese in 1490.
Also, the SETI ("Search for ExtraTerrestrial Intelligence") institute has some pages which may be useful:

For example, SETI, the search for extraterrestrial intelligence, got its start in Green Bank. Here, in 1960, Dr. Frank Drake, a young radio astronomer, pointed an 85-foot telescope at two nearby, Sun-like stars: Tau Ceti and Epsilon Eridani.
As with other SETI methods, they rely on the assumption that aliens would use Earth-like technologies.
Several decades of SETI analysis have not revealed any main sequence stars with unusually bright, or meaningfully repetitive radio emissions, although there have been several candidate signals: on August 15 1977 the "Wow! ...

Projects such as SETI are conducting an astronomical search for radio activity that would confirm the presence of intelligent life.

There are Search for Extra Terrestrial Intelligence (SETI) projects active at the privately funded SETI-Institute/Project Phoenix2 in California, as well as at Harvard and Berkley universities.
SETI, (the search for extra terrestrial intelligence), represents a relatively tiny portion of radio astronomy.
The SETI (Search for Extraterrestrial Intelligence) Institute, a privately-funded, non-profit organization that had been working on the HRMS, took over part of the effort aimed at discovering exterrestrial signals.
This telescope will be built in California's Cascade Mountains and will be a joint effort between the SETI (Search for Extraterrestrial Intelligence) Institute and the University of California, Berkeley.
Harnessing the Power of the Sun SETI - April 20, 2007
Science, even by reputable practitioners, proceeds in fits, starts, and frequent excursions down blind alleys.
An array of up to 350 radio telescopes (previously known as the One Hectare Telescope), which will be used extensively for SETI in parallel with other astronomy.

SETI and CETI advocates do generally not claim that extraterrestrials exist, although most consider the possibility likely (see Drake equation).
If you are looking for someone to talk to, then SETI (Search for Extraterrestrial Intelligence) is for you. You can join the SETI@home project and help us look for signs of intelligent radio signals! ...
It is also the closest Sun-like star to Earth that is not a component of a binary or multiple star system. Astronomers Margaret Turnbull and Jill Tarter of the SETI (Search for Extra-Terrestrial Intelligence) Institute called [6198] delta Pavonis ...

Hubble sees moons and rings in 2005. The distant planet continues to surprise astronomers. Using NASA's Hubble Space Telescope in 2005, they uncovered a pair of giant rings girdling the planet.
Refers to a signal with an apparent time rate of change in its typical frequency. All signals drift to some extent. In a SETI system, the dominant drift should be largely the result of only the time rate of change in the Doppler shift (q.v.).
Sagan also showed that the universe has many organic (carbon-based) chemicals and that life is likely to exist throughout the cosmos. He was a great popularizer of astronomy, was also involved in many NASA flights and SETI, ...
and it would take millennia to image every star for planets, and even longer if scientists tried to send a radio signal to every planet in every extrasolar system. So by assuming that extraterrestrial life is carbon-based, scientists who are in SETI ...
"The new discoveries dramatically demonstrate that Uranus has a youthful and dynamic system of rings and moons," remarked Mark Showalter of the SETI Institute. "Until now, nobody had a clue the rings were there, we had no right to expect them." ...
Tau Ceti achieved its true fame in 1960, when Frank Drake initiated "Project Ozma," an attempt to detect intelligent signals from space and the opening salvo in modern SETI, the Search for Extraterrestrial Intelligence.
