Technosignatures represent any signs of technology that we can use to infer the existence of intelligent life in other parts of the universe, including familiar search engines for extraterrestrial intelligence, such as narrow-band radio signals or pulsed lasers. The term SETI (search for extraterrestrial intelligence) is often used synonymously with searching for technology signatures. Unlike biosignatures, many proposed techno-signatures are self-luminous or involve manipulation of energy from bright natural sources. Furthermore, since the technological life scattered throughout the galaxy can be immense, technological signatures can be found far away in both space and time from their point of abiogenesis. Compared to biological signatures, technology signatures can therefore be more ubiquitous, more obvious, more unambiguous, and detectable at much greater (even extragalactic) distances. The term «techno-signatures», a contraction of «technology firms» or «technology firms», appears for the first time in the scientific literature in an article written in 2007 by Jill Tarter (2007), who wrote: technological firms, as evidence of some technology that is capable of modifying its environment in a detectable way, then we can infer the existence, at least at some point, of intelligent technologies ”(Report from the NASA Technosignatures Workshop - November 28 - 2018 pg. EXTRATERRANOVAS studies "apparent" graphics on the lunar and martian surface and the so-called crop circles; Likewise, it analyzes sound emissions from space and contributes to theorizing about expolitics, exosociology, exobiology and ethnoastronomy; it also develops computer programs for the advancement of space exploration.
