\u00cen 2008, Telescopul Spa\u021bial Hubble al NASA\/ESA a descoperit dioxid de carbon \u00een atmosfera unei planete de dimensiunea lui Jupiter care orbiteaz\u0103 \u00een jurul unei alte stele. Aceast\u0103 descoperire a fost considerat\u0103 un pas important \u00een c\u0103utarea dovezilor existen\u021bei vie\u021bii pe alte lumi.<\/p>\n<\/div>\n

P\u00e2n\u0103 \u00een prezent, au fost descoperite aproximativ 300 de planete care orbiteaz\u0103 \u00een jurul unor stele \u00eendep\u0103rtate. Din p\u0103cate, aceste planete extrasolare sunt at\u00e2t de slab vizibile \u0219i at\u00e2t de \u00eendep\u0103rtate, \u00eenc\u00e2t este extrem de dificil s\u0103 le studiem. Cu toate acestea, cu ajutorul instrumentelor moderne, oamenii de \u0219tiin\u021b\u0103 \u00eencep treptat s\u0103 afle mai multe despre aceste lumi str\u0103ine \u0219i despre gazele care alc\u0103tuiesc atmosferele lor.<\/p>\n

Dioxidul de carbon este gazul pe care plantele \u00eel elibereaz\u0103 \u00een timpul nop\u021bii \u0219i pe care \u00eel utilizeaz\u0103 pentru a cre\u0219te. Animalele \u0219i oamenii \u00eel expir\u0103 la fiecare c\u00e2teva secunde. Fiind unul dintre principalii gaze cu efect de ser\u0103, acesta re\u021bine c\u0103ldura \u0219i contribuie la \u00eenc\u0103lzirea planetei. Carbonul st\u0103, de asemenea, la baza a\u0219a-numi\u021bilor compu\u0219i organici, care se num\u0103r\u0103 printre elementele constitutive ale vie\u021bii. Acum, telescopul Hubble a demonstrat c\u0103 putem detecta dioxidul de carbon pe planete \u00eendep\u0103rtate \u0219i putem estima cantitatea prezent\u0103. Acesta reprezint\u0103 un progres major \u00een efortul pe termen lung de a afla din ce sunt alc\u0103tuite aceste lumi \u0219i dac\u0103 ar putea sus\u021bine via\u021ba.<\/p>\n

Planeta, denumit\u0103 HD 189733b, este prea fierbinte pentru a g\u0103zdui via\u021b\u0103. Cu toate acestea, este o planet\u0103 potrivit\u0103 pentru observare, deoarece dispare \u00een spatele stelei sale \u00eenso\u021bitoare o dat\u0103 la 2,2 zile. Studiind varia\u021biile regulate ale luminii care ajunge pe P\u0103m\u00e2nt, oamenii de \u0219tiin\u021b\u0103 pot analiza atmosfera planetei. Au fost deja detectate vapori de ap\u0103 \u0219i metan. Noile observa\u021bii realizate de telescopul Hubble demonstreaz\u0103 c\u0103 elementele chimice de baz\u0103 necesare vie\u021bii pot fi m\u0103surate pe planete care orbiteaz\u0103 \u00een jurul altor stele.<\/p>","protected":false},"excerpt":{"rendered":"
