by The Search for Extraterrestrial Intelligence (Seti) constitutes a branch of astronomy dedicated to finding extraterrestrial life by searching for unusual signals, dubbed technosignatures.
The identification of a technosignature wouldn’t just signify the existence of life, but specifically point to the presence of intelligent life using advanced technology.
Seti makes the assumption that extraterrestrial civilisations might rely on technology in a similar way to people on Earth, such as using cell phones, satellites or radar.
Since a significant portion of such technology generates signals that are prominently detectable in radio frequencies, focusing on these wavelengths serves as a logical starting point in the quest for potential extraterrestrial intelligence.
