Les exoplanètes, c’est-à-dire les planètes situées en dehors de notre Système solaire, sont extrêmement difficiles à photographier directement en raison de leur éloignement de la Terre et de leur proximité avec des étoiles brillantes.\u003cbr\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTélescope spatial Hubble : découvertes \u0026amp; héritage\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eEn 2000, Hubble a étudié HD 209458 b – la première exoplanète connue pour effectuer un transit, c’est-à-dire passer devant son étoile. Hubble a également été le \u003cstrong\u003epremier télescope à détecter directement l’atmosphère d’une exoplanète\u003c\/strong\u003e, en observant la lumière de l’étoile qui la traversait. Grâce à cette méthode de « spectroscopie de transit », Hubble a observé les signatures du sodium dans l’atmosphère de la planète.\u003cbr\u003e\u003cbr\u003eEn 2018, Hubble a étudié le \u003cstrong\u003esystème planétaire TRAPPIST-1\u003c\/strong\u003e.
