"technosignatures"

The Galileo Project is looking for intelligent life in our universe, but not through radio or light signals, but rather physical objects:

"Rather than searching for electromagnetic signals, the Galileo Project will search for physical objects associated with extraterrestrial technological equipment, also known as technosignatures.

The project will follow three major avenues of research: obtain high-resolution images of UAP through multi-detector sensors to discover their nature, search and conduct in-depth research on 'Oumuamua-like' interstellar objects, and search for potential ETC satellites.

'It is very important that we keep in mind that the Galileo Project is not for everything, and it is not for everyone,' said Laukien. 'It has a defined scope, and it has limitations,' he added, referring to the project’s aim of only exploring known physics explanations rather than speculating on prior UAPs [unidentified aerial phenomena], alleged observations and informal reports."

It's becoming clearer by the day that the Earth would be better off without humans.  And I love the phrase "technosignature," even though it's klunky as hell.
