Term: Search for extraterrestrial intelligence

The scientific attempt to detect intelligent extraterrestrial life by surveying the sky to find the existence of transmissions, especially radio waves or light, from a civilization on a distant planet. The SETI Institute, that carries out the project, is a private non-profit center founded in 1984. There are many methods that SETI scientific teams use to search for extraterrestrial intelligence. Many of these search billions of radio frequencies that reach Earth from all over the Universe, looking for an intelligent radio signal. Other SETI teams search by looking for signals in pulses of light emanating from the stars.
