Space, the final frontier: In the scientific pursuit of extraterrestrial life away from Earth

For decades we have been searching for an answer to the knotty question, “do aliens exist?.” Other questions in line are: “where are they?,” “are they like us, sophisticated intelligent beings?” or “do they exist in the form of simpler lifeforms?,” “Have they ever visited us?,” “Why haven’t we encountered them yet?,” “or have we?” To satiate this curiosity, astrophysicists and astronomers have come up with innumerable theories and ideas, engaged in building facilities and institutes and come up with a planet-wide effort for the search of extraterrestrial intelligence — SETI@home. This article will take a ride through time, from the first documented idea to look for extraterrestrial beings to the current exploration of this field.

 

Depuis des décennies, nous cherchons une réponse à la question délicate : « Les extraterrestres existent-ils ? » D’autres interrogations se posent également: "Où sont-ils ?", "Sont-ils comme nous, des êtres intelligents et sophistiqués ?" ou  "Existent-ils en tant que formes de vie plus simples ?", "Nous ont-ils déjà rendu visite ?", "Pourquoi ne les avons-nous pas encore rencontrés ?", "Ou les avons-nous rencontrés ?" Pour satisfaire cette curiosité, les astrophysiciens et les astronomes ont élaboré d’innombrables théories et idées, et ont construit des équipements et des instituts. Ils ont également lancé un effort planétaire pour la recherche d’une intelligence extraterrestre — SETI@home. Cet article va vous faire voyager à travers le temps, de la première idée documentée de recherche d’êtres extraterrestres à l’exploration actuelle de ce domaine.
