Le champ de recherche des exoplan\u00e8tes recouvre 3 r\u00e9volutions : Jusque 1995, nous n\u2019avions pas de preuve de leur existence. D\u00e8s les premi\u00e8res d\u00e9couvertes de ces autres syst\u00e8mes, leur diversit\u00e9 a suscit\u00e9 un grand \u00e9tonnement : le syst\u00e8me solaire serait-il un cas sp\u00e9cifique? Enfin, les \u00a0principales missions spatiales de traque des exoplan\u00e8tes ont aujourd\u2019hui aboutit \u00e0 une conclusion : la plupart des \u00e9toiles sont entour\u00e9es de plan\u00e8tes rocheuses, semblables \u00e0 la Terre\u2026 Mais jusqu\u2019o\u00f9?<\/p>\n<\/div>\n<\/div>\n<\/div>\n

La Terre sous le d\u00e9luge des exoplan\u00e8tes<\/strong><\/span>
par Alice Mounissamy
<\/span>
Depuis plus de 20 ans, nous savons que les exoplan\u00e8tes existent. Imagin\u00e9es d\u00e8s l\u2019antiquit\u00e9 grecque, les m\u00e9thodes pour les d\u00e9tecter n\u2019ont \u00e9t\u00e9 th\u00e9oris\u00e9es qu\u2019en 1952 par l\u2019astronome am\u00e9ricano-russe Otto Struve. Il faudra encore attendre 1995, \u00e0 l\u2019observatoire de Haute Provence, pour que les astrophysiciens Didier Queloz et Jacques Mayor en discernent les premi\u00e8res \u00e9clipses. Ces autres mondes peuplant notre galaxie, d\u00e9sormais \u00e0 port\u00e9e de t\u00e9lescope, ouvrirent alors de nouvelles perspectives pour comprendre ce qu\u2019\u00e9tait la Terre. Cette r\u00e9volution profonde tant dans le champ de l\u2019astrophysique comme dans notre mani\u00e8re d\u2019imaginer notre place au sein de l\u2019Univers est encore aujourd\u2019hui jalonn\u00e9e de surprise !<\/span><\/p>\n
