Xenoarchaeology, a branch of xenology dealing with extraterrestrial cultures, is a hypothetical form of archaeology that exists mainly in works of science fiction. The field is concerned with the study of the material remains to reconstruct and interpret past life-ways of alien civilizations.
Archaeology, Anthropology, and Interstellar Communication is subdivided into four sections, each with several essays. "Historical Perspectives on SETI" is a historiography of NASA's SETI (search for extraterrestrial intelligence) program, which ran for much of the late twentieth century before being dissolved due to lack of funding, and its humanities and social sciences representation.
[5] A Daily Kos book reviewer writes that Interstellar "provides a realistic and practical blueprint for how a [human and alien life] interaction might actually occur, resetting our cultural understanding and expectation of what it means to identify an extraterrestrial object. ... [the author] also lays out the profound implications of becoming ...
Extraterrestrial intelligence (ETI) refers to hypothetical intelligent extraterrestrial life. No such life has ever been verifiably observed to exist. [ 1 ] The question of whether other inhabited worlds might exist has been debated since ancient times. [ 2 ]
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.
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]
Such meetings have generally led to the destruction of the civilization receiving contact (as opposed to the "contactor", which initiates contact), and therefore destruction of human civilization is a possible outcome. [2] Extraterrestrial contact is also analogous to the numerous encounters between non-human native and invasive species ...
A question is whether the dark, alien oceans of the outer Solar System could be habitable for simple life forms, and if so, what their biochemistry might be. [ 16 ] The goals of the Ocean Worlds Exploration Program are to "identify ocean worlds, characterize their oceans, evaluate their habitability, search for life, and ultimately understand ...
