The SETI Institute named the telescope in Allen's honor. Overall, Paul Allen contributed more than $30 million to the project. The ATA is a centimeter-wave array which pioneers the Large-Number Small-Diameter concept of building radio telescopes.
The search for extraterrestrial intelligence (SETI) is a collective term for scientific searches for intelligent extraterrestrial life.Methods include monitoring electromagnetic radiation for signs of transmissions from civilizations on other planets, [1] [2] [3] optical observation, and the search for physical artifacts.
The Berkeley SETI Research Center also hosts the Breakthrough Listen program, [4] [5] [6] which is a ten-year initiative with $100 million funding begun in July 2015 to actively search for intelligent extraterrestrial communications in the universe, in a substantially expanded way, using resources that had not previously been extensively used for the purpose.
As of April 2016, the targets for the radio search with the Green Bank Radio Telescope in the Northern Hemisphere include the following: [4] All 43 stars within 5 parsec, or 16.3 light-years, or 1.03 million astronomical units, or 1.545 × 10 14 kilometres; 1000 stars of all spectral-types within 50 pc, or 163 ly, or 10.3 million au, or 1.545 ...
NASA SETI (Search for Extraterrestrial Intelligence) Microwave Observing Project sites in 1992. The communication with extraterrestrial intelligence (CETI) is a branch of the search for extraterrestrial intelligence (SETI) that focuses on composing and deciphering interstellar messages that theoretically could be understood by another technological civilization. [1]
These instruments have been deployed at a large number of telescopes including the NRAO 90m telescope at Green Bank and the Arecibo 305m telescope. SERENDIP observations have been conducted at frequencies between 400 MHz and 5 GHz , with most observations near the so-called Cosmic Water Hole (1.42 GHz (21 cm) neutral hydrogen and 1.66 GHz ...

Active SETI (Active Search for Extra-Terrestrial Intelligence) is the attempt to send messages to intelligent extraterrestrial life. Active SETI messages are predominantly sent in the form of radio signals. Physical messages like that of the Pioneer plaque may also be considered an active SETI message.
