SETI (Search For Extra Terrestrial intelligence) broadcasts radio frequencies that are clear they are from intelligent life forms. So if a civilization were to pick it up they know its not random.
SETI (Search for Extra-Terrestrial Intelligence), uses scientific methods to look for electromagnetic transmissions to see if there are civilizations on any distant planets.
If you mean extraterrestrial life, so far no such discovery has been announced.
It means Search for Extra-Terrastrial Intelligence.
SETI (Search for Extra-Terrestrial Intelligence) is the name for the private program (privately funded and operated) searching for evidence of extraterrestrial life. Contrary to popular belief and assumption, NASA has nothing to do with the SETI project.
The SETI institute, is an organisation that searches for evidence of extra terrestrial life. It does this by searching for the signals off of technological civilizations. There are two separate branches of the institute which each focus on different areas. The research and development branch works to create new technology and algorithms to further their search, whilst the projects branch implements the use of this technology to search for extra terrestrial life and inspire new research.
There are no such thing as aliens
Because some people consider the question "Are we alone in the universe ?" important
Well... You could help S.E.T.I. By helping them to search for extraterrestrials (Aliens)Seti@home needs your helpWhat is SETI@home?SETI@home is a scientific experiment that uses Internet-connected computers in the Search for Extraterrestrial Intelligence (SETI). You can participate by running a free program that downloads and analyzes radio telescope data.The address is: http://setiathome.berkeley.edu
SETI: The Search for Extraterrestrial Intelligence
SETI stands for Search for Extra-Terrestrial Intelligence
There is no one SETI program. The name is a collective term for act ivies that search for intelligent extraterrestrial life. SETI stands for Search for Extraterrestrial Intelligence.
It broadcasts radio signals to the sky, so that aliens can figure out that an intelligence exists on Earth, and find us.
Search for Extraterrestrial Intelligence
The Aricibo Radio telescope in Puerto Rico was used to send a message into space in 1974 with the power of I Giga Watt in the SETI program (Search for Extra Terrestrial Intelligence)
Since 1959 scientists have been developing the SETI program. Basically, SETI is a listening exercise. Scientists using radio telescope arrays around the world listen for transmissions from extraterrestrial intelligences. Aside from the work done by NASA, RKA, JAXA, CSA, and ESA and several independent scientific space agencies, SETI is probably one of the only programs recognized as legitimate in the search for extraterrestrial life.
It means Search for Extra-Terrastrial Intelligence.
The Search for Extraterrestrial Intelligence or SETI are the not for profit organization that has a goal to search, explore, understand and explain the nature, prevalence and nature of the lives of the whole universe. This organization is founded by Frank Drake and Carl Sagan.
As such astronauts do not search for life. It is not quite as simple as looking a the window of a space station and seeing aliens going past. They can search for life by taking rock samples of planets and searching for bacteria but most of the search for life is done using telescopes to find radio waves being sent out by intelligent lifeforms. You could help this by joining the SETI program.
No, the SETI program (Search for Extra-Terrestrial Intelligence) program pre-dates Sagan, but he was a fervent promoter of it. If any one person could be said to have "invented" SETI, it would have been Frank Drake.
