La fascination des ailleurs: chasseurs de planètes

Description

Le 6 octobre 1995, deux astronomes genevois, Michel Mayor et Didier Queloz, annoncent la découverte de la première planète observée autour d’une étoile autre que le Soleil. L’enjeu est de taille: si d’autres planètes peuplent l’espace extrasolaire, notre globe n’est peut-être pas le seul monde habité du cosmos. Désormais, notre civilisation peut rêver à l’existence de petites ou de grandes soeurs nées en divers points de la Galaxie. A moins que, étrangement, notre espèce ne soit seule au monde… Au fil de ces pages, François Rothen retrace de façon claire et accessible le contexte historique et les circonstances de la découverte des exoplanètes, ainsi que les perspectives qu’elle ouvre dans la compréhension de l’univers lointain. Un voyage passionnant, la tête dans les étoiles, sur les traces des plus illustres esprits d’hier et d’aujourd’hui.
