Africa-Press<\/a> – Cameroun<\/a>. <\/strong><\/span>C’est une d\u00e9couverte surprenante r\u00e9v\u00e9l\u00e9e par le t\u00e9lescope spatial Hubble : une exoplan\u00e8te rocheuse disposerait d’une atmosph\u00e8re \u00ab\u00a0secondaire\u00a0\u00bb, ou r\u00e9g\u00e9n\u00e9r\u00e9e. L’\u00e9tude des images fournies par Hubble a permis de distinguer une activit\u00e9 volcanique sur cette plan\u00e8te baptis\u00e9e GJ 1132 b et situ\u00e9e \u00e0 41 ann\u00e9es lumi\u00e8res du syst\u00e8me solaire. C’est la premi\u00e8re fois qu’une atmosph\u00e8re secondaire est d\u00e9tect\u00e9e sur une plan\u00e8te hors du syst\u00e8me solaire.<\/p>\n

\u00ab\u00a0Nous avons d’abord pens\u00e9 que ces plan\u00e8tes fortement irradi\u00e9es \u00e9taient assez ‘ennuyeuses’, car nous pensions qu’elles avaient perdu leur atmosph\u00e8re\u00a0\u00bb, a d\u00e9clar\u00e9 Raissa Estrella, co-auteur de l’\u00e9tude au Jet Propulsion Laboratory de la NASA \u00e0 Pasadena (Californie), dans une note scientifique publi\u00e9e par la NASA et l’ESA, l’Agence spatiale europ\u00e9enne. \u00ab\u00a0C’est passionnant, car nous pensons que l’atmosph\u00e8re que nous voyons aujourd’hui a \u00e9t\u00e9 r\u00e9g\u00e9n\u00e9r\u00e9e.\u00a0\u00bb<\/p>\n

La combinaison d’observations directes et de mod\u00e9lisations informatiques ont permis d’\u00e9tablir que cette atmosph\u00e8re secondaire \u00e9tait constitu\u00e9e d’hydrog\u00e8ne, de cyanure d’hydrog\u00e8ne, de m\u00e9thane, d’ammoniac et d’une brume d’hydrocarbures, alors que l’atmosph\u00e8re primaire de GJ 1132 b aurait plut\u00f4t \u00e9t\u00e9 constitu\u00e9e d’hydrog\u00e8ne et d’h\u00e9lium. Les \u00e9tudes des astronomes sugg\u00e8rent que l’hydrog\u00e8ne initial pourrait avoir \u00e9t\u00e9 \u00ab\u00a0absorb\u00e9\u00a0\u00bb par le manteau de magma en fusion de l’exoplan\u00e8te. Il serait \u00e0 pr\u00e9sent lib\u00e9r\u00e9 par ph\u00e9nom\u00e8ne volcanique, formant cette nouvelle atmosph\u00e8re. L’\u00e9quipe scientifique fait l’hypoth\u00e8se que la cro\u00fbte terrestre de GJ 1132 b est tr\u00e8s fine et qu’elle serait trop fragile pour supporter un quelconque relief ressemblant \u00e0 des montagnes volcaniques. Le terrain plat pourrait \u00eatre fissur\u00e9, \u00e0 l’image d’une coquille d’\u0153uf, ce qui pourrait expliquer la lib\u00e9ration de l’hydrog\u00e8ne et autres gaz.<\/p>\n

Cette d\u00e9couverte est importante, car elle donne aux scientifiques travaillant sur les exoplan\u00e8tes un moyen de mieux comprendre la g\u00e9ologie d’une plan\u00e8te \u00e0 partir de son atmosph\u00e8re\u00a0\u00bb, explique Paul Rimmer, de l’Universit\u00e9 de Cambridge (Royaume-Uni) dans le communiqu\u00e9. \u00ab\u00a0Cette atmosph\u00e8re secondaire provient de la surface et de l’int\u00e9rieur de la plan\u00e8te, et c’est donc une fen\u00eatre qui s’ouvre sur la g\u00e9ologie d’un autre monde\u00a0\u00bb, poursuit Paul Rimmer. \u00ab\u00a0Il reste encore beaucoup de travail \u00e0 faire pour regarder \u00e0 travers, mais la d\u00e9couverte de cette fen\u00eatre est d’une grande importance.\u00a0\u00bb<\/p>\n

Lorsque les astronomes utiliseront le futur t\u00e9lescope spatial James Webb pour \u00e9tudier GJ 1132 b, il est possible qu’ils puissent observer \u00ab\u00a0non pas le spectre de l’atmosph\u00e8re, mais plut\u00f4t le spectre de la surface\u00a0\u00bb et donc une activit\u00e9 g\u00e9ologique r\u00e9elle, avance Mark Swain, chef d’\u00e9quipe au Jet Propulsion Laboratory.<\/p>\n

GJ1132 b et la Terre partagent quelques points communs : toutes deux pr\u00e9sentent une densit\u00e9, une taille et un \u00e2ge similaires et disposeraient d’une atmosph\u00e8re compos\u00e9e en grande partie d’hydrog\u00e8ne au d\u00e9but et ont \u00e9t\u00e9 chauff\u00e9es avant de refroidir. Les \u00e9tudes men\u00e9es par les astronomes sugg\u00e8rent qu’elles auraient la m\u00eame pression atmosph\u00e9rique \u00e0 la surface.<\/p>\n","protected":false},"excerpt":{"rendered":"
