W 2008 roku teleskop kosmiczny Hubble\u2019a, wsp\u00f3lny projekt NASA i ESA, wykry\u0142 dwutlenek w\u0119gla w atmosferze planety wielko\u015bci Jowisza kr\u0105\u017c\u0105cej wok\u00f3\u0142 innej gwiazdy. Uznano to za wa\u017cny krok w poszukiwaniu \u015blad\u00f3w \u017cycia na innych \u015bwiatach.<\/p>\n<\/div>\n

Do tej pory odkryto oko\u0142o 300 planet kr\u0105\u017c\u0105cych wok\u00f3\u0142 odleg\u0142ych gwiazd. Niestety, te planety pozas\u0142oneczne s\u0105 tak s\u0142abo widoczne i znajduj\u0105 si\u0119 tak daleko, \u017ce niezwykle trudno jest je bada\u0107. Jednak dzi\u0119ki nowoczesnym urz\u0105dzeniom naukowcy stopniowo zaczynaj\u0105 dowiadywa\u0107 si\u0119 wi\u0119cej o tych obcych \u015bwiatach i gazach tworz\u0105cych ich atmosfery.<\/p>\n

Dwutlenek w\u0119gla to gaz, kt\u00f3ry ro\u015bliny wydzielaj\u0105 w nocy i wykorzystuj\u0105 do wzrostu. Zwierz\u0119ta i ludzie wydychaj\u0105 go co kilka sekund. Jako jeden z g\u0142\u00f3wnych gaz\u00f3w cieplarnianych zatrzymuje ciep\u0142o i przyczynia si\u0119 do ocieplania planety. W\u0119giel stanowi r\u00f3wnie\u017c podstaw\u0119 tzw. zwi\u0105zk\u00f3w organicznych, kt\u00f3re nale\u017c\u0105 do budulca \u017cycia. Teraz teleskop Hubble'a wykaza\u0142, \u017ce mo\u017cemy wykrywa\u0107 dwutlenek w\u0119gla na odleg\u0142ych planetach i oszacowa\u0107 jego ilo\u015b\u0107. Jest to znacz\u0105cy post\u0119p w d\u0142ugotrwa\u0142ych wysi\u0142kach maj\u0105cych na celu ustalenie, z czego sk\u0142adaj\u0105 si\u0119 te \u015bwiaty i czy mog\u0142yby one sprzyja\u0107 \u017cyciu.<\/p>\n

Planeta o nazwie HD 189733b jest zbyt gor\u0105ca, by mog\u0142o na niej istnie\u0107 \u017cycie. Stanowi jednak dobry obiekt do obserwacji, poniewa\u017c co 2,2 dnia znika za swoj\u0105 gwiazd\u0105 macierzyst\u0105. Badaj\u0105c regularne zmiany nat\u0119\u017cenia \u015bwiat\u0142a docieraj\u0105cego do Ziemi, naukowcy mog\u0105 analizowa\u0107 atmosfer\u0119 tej planety. Wykryto ju\u017c par\u0119 wodn\u0105 i metan. Nowe obserwacje teleskopu Hubble\u2019a dowodz\u0105, \u017ce na planetach kr\u0105\u017c\u0105cych wok\u00f3\u0142 innych gwiazd mo\u017cna zmierzy\u0107 podstawowe sk\u0142adniki chemiczne niezb\u0119dne do powstania \u017cycia.<\/p>","protected":false},"excerpt":{"rendered":"
