NASA and the Search for Technosignatures: A Report from the NASA Technosignatures Workshop
, 2018 This report is the product of the NASA Technosignatures Workshop held at the Lunar and Planetary Institute in Houston, Texas, in September 2018. This workshop was convened by NASA for the organization to learn more about the current field and state of the art of searches for technosignatures, and what role NASA might play in these searches in the ...

Demography of galactic technosignatures [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Probabilistic arguments about the existence of technological life beyond Earth traditionally refer to the Drake equation to draw possible estimates of the number of technologically advanced civilizations releasing, either intentionally or not, electromagnetic emissions in the Milky Way.

A Search for Radio Technosignatures from Interstellar Object 3I/ATLAS with the Allen Telescope Array
The Astronomical JournalIn 2025 July, the third-ever interstellar object, 3I/ATLAS, was discovered on its ingress into the solar system. Similar to the NASA Voyager missions sent in 1977, science probes by extraterrestrial life (“artifact technosignatures”) could be sent to ...

A Search for Extraterrestrial Technosignatures in Archival FAST Survey Data Using a New Procedure [PDF]
The Astronomical Journal, 2023 The search for extraterrestrial intelligence (SETI) commensal surveys aim to scan the sky to find possible technosignatures from an extraterrestrial intelligence (ETI). The mitigation of radio frequency interference (RFI) is an important step, especially

The Fermi Paradox Revisited: Technosignatures and the Contact Era [PDF]
The Astrophysical Journal, 2022 Abstract A new solution to the Fermi Paradox is presented: probes or visits from putative alien civilizations have a very low probability until a civilization reaches a certain age (called the “Contact Era”) after the onset of radio communications.

Evaluation of Several Computer Vision Feature Detectors/Extractors on Ahuna Mons Region in Ceres and Its Implications for Technosignatures Search. [PDF]
Vision (Basel), 2022 Ahuna Mons is a 4 km particular geologic feature on the surface of Ceres, of possibly cryovolcanic origin. The special characteristics of Ahuna Mons are also interesting in regard of its surrounding area, especially for the big crater beside it.
