The Green Bank Telescope is one of the radio telescopes used by the Breakthrough Listen project to search for alien communications. Although most searches are focused on the biology of extraterrestrial life, an extraterrestrial intelligence capable enough to develop a civilization may be detectable by other means as well.
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.
Space colonization has been in a broad sense referred to as space settlement, space humanization or space habitation. [16] Space colonization in a narrow sense refers to space settlements, as envisioned by Gerard K. O'Neill. [17] It is characterized by elements such as: settlement and exploitation, [18] as well as territorial claim. [19]
In the SETILive project, which began in 2012, human volunteers analyze data from the Allen Telescope Array to search for possible alien signals that computers might miss because of terrestrial radio interference. [15] The data for the study is obtained by observing Kepler target stars with the radio telescope. [12]
[1] [2] The project began in January 2016, and is expected to continue for 10 years. [4] It is a component of Yuri Milner's Breakthrough Initiatives program. The science program for Breakthrough Listen is based at Berkeley SETI Research Center, [5] [6] located in the Astronomy Department [7] at the University of California, Berkeley.

The extraterrestrial hypothesis is the idea that some UFOs are vehicles containing or sent by extraterrestrial beings (usually called aliens in this context). [13] As an explanation for UFOs, ETI is sometimes contrasted with EDI (extradimensional intelligence), for example by J. Allen Hynek. [24]
In its June 2022 announcement of plans to form the UAPIST, NASA named astrophysicist David Spergel as the chair of the team, and Daniel Evans, the assistant deputy associate administrator for research at NASA's Science Mission Directorate, as the official responsible for orchestrating the study. The team's objective, according to Spergel, was ...
