Technosignatures Could be Key to Finding Alien Life on Exoplanets

Technosignatures from exoplanets could be the way forward in humankind’s search for alien life on other planets, according to a new research paper.

Atmospheric industrial pollution, satellite swarms or huge constructions in space, such as Dyson spheres – hypothetical technology designed to capture energy from stars – could all reveal the presence of intelligent life elsewhere.

Researchers from the Instituto de Astrofisica de Canarias (IAC) teamed up with experts to publish the paper in the journal Acta Astronautica.

“Some of the proposed searches look very far in space, across our galaxy and even beyond, while others aim at scanning our own solar system in search for probes that might have been sent here in a distant past,” read the paper.

“We have no idea whether intelligence is something very common in the universe or, on the contrary, whether it is extremely rare,” explained Dr Hector Socas-Navarro.

“For that reason we cannot know whether these searches have any chance of success. There is no choice but to search and see what we find, because the implications would be tremendous.”
