Concepts for future missions to search for technosignatures
Acta Astronautica, 2021 New and unique opportunities now exist to look for technosignatures (TS) beyond traditional SETI radio searches, motivated by tremendous advances in exoplanet science and observing capabilities in recent years.

A Search for Technosignatures Around 11,680 Stars with the Green Bank Telescope at 1.15–1.73 GHz
The Astronomical Journal, 2023 We conducted a search for narrowband radio signals over four observing sessions in 2020–2023 with the L -band receiver (1.15–1.73 GHz) of the 100 m diameter Green Bank Telescope.

COSMIC’s Large-scale Search for Technosignatures during the VLA Sky Survey: Survey Description and First Results [PDF]
The Astronomical JournalDeveloping algorithms to search through data efficiently is a challenging part of searching for signs of technology beyond our solar system. We have built a digital signal processing system and computer cluster on the backend of the Karl G.

An Extragalactic Widefield Search for Technosignatures with the Murchison Widefield Array
Astrophysical JournalIt is common for surveys that are designed to find artificial signals generated by distant civilizations to focus on galactic sources. Recently, researchers have started focusing on searching for all other sources within the field observed, including the

A note on the Vukotić-Gordon mini-earths [PDF]
Serbian Astronomical Journal, 2023 A recent proposal for a new kind of astroengineering artifact due to Vukotić and Gordon (2022) is discussed, in particular in light of multiple benefits offered by the magnetic Penrose process.

Polycyclic Aromatic Hydrocarbons as an Extraterrestrial Atmospheric Technosignature
The Planetary Science JournalPolycyclic aromatic hydrocarbons (PAHs) are prevalent in the Universe and interstellar medium but are primarily attributed to anthropogenic sources on Earth, such as fossil fuel combustion and firewood burning.

Life detection in a universe of false positives
BioEssays, Volume 45, Issue 12, December 2023., 2023 The ultimate goal of astrobiology is to determine the distribution and diversity of life in the universe. But there's a big problem: Most of the planets in our universe are outside our reach. For these exoplanets, can we really ever be certain if they contain life or not?

Technosignatures as a Priority in Planetary Science [PDF]
Bulletin of the AAS, 2021 Are we alone? The study of technosignatures, physical manifestations of technology from extraterrestrial intelligences, is a rigorous astrobiological sub-discipline. The Planetary Science decadal should include searches for technosignatures alongside biosignatures in its recommendations for funding a robust astrobiology research portfolio.
