New Concept: [technosignatures] #290

Closed astrowright closed 4 years ago

Technosignatures

Describe the concept Best description is here: https://arxiv.org/abs/1809.06857 From that work: Any sign of technology that is not also a biosignature (i.e. that is not also a sign or byproduct of metabolism in common with non-technological species). Notes: By analogy with biosignature, technosignature refers to signs or signals, which, if observed, would allow us to infer the existence of technological life elsewhere in the universe; this tracks the natural meaning of the word and the intent of its original coinage (see Tarter (2007) Highlights of Astronomy 14, 14). In some cases, the line between biosignatures and technosignatures may be unclear, and technology need not be of biological origin, as in the case of “postbiological evolution.”

Describe where the concept fits within the existing hierarchy It could be considered a subset of astrobiology. Others would consider it distinct.

Provide 1-3 supporting articles List bibcodes or other identifiers for articles that support the need for this new concept in the literature. 2018arXiv180906857W 2018arXiv181208681T 2007HiA....14...14T

Please include any additional comments/feedback Heavy overlap if not outright synonymy with the old keyword "extraterrestrial intelligence."
