Projections of Earth’s Technosphere: Strategies for Observing Technosignatures on Terrestrial Exoplanets

The Astrophysical Journal Letters
The search for technosignatures—remotely detectable evidence of extraterrestrial technology—draws upon examples from the recent history of Earth as well as projections of Earth’s technosphere.

The NASA SETI sky survey: Recent developments [PDF]

NASA's Search for Extraterrestrial Intelligence (SETI) project utilizes two complementary search strategies: a sky survey and a targeted search. The SETI team at the Jet Propulsion Laboratory (JPL) in Pasadena, California, has primary responsibility to ...

Starry Messages: Searching for Signatures of Interstellar Archaeology

, 2009
Searching for signatures of cosmic-scale archaeological artifacts such as Dyson spheres or Kardashev civilizations is an interesting alternative to conventional SETI.

Searching the SN 1987A SETI Ellipsoid with TESS

The Astronomical Journal
The SETI Ellipsoid is a strategy for technosignature candidate selection that assumes that extraterrestrial civilizations who have observed a galactic-scale event—such as supernova 1987A—may use it as a Schelling point to broadcast synchronized signals ...

Anomaly Detection and Radio-frequency Interference Classification with Unsupervised Learning in Narrowband Radio Technosignature Searches

The Astronomical Journal
The search for radio technosignatures is an anomaly detection problem: Candidate signals represent needles of interest in the proverbial haystack of radio-frequency interference (RFI). Current search frameworks find an enormity of false-positive signals,
