Leta 2008 je vesoljski teleskop Hubble, ki ga upravljata NASA in ESA, odkril ogljikov dioksid v atmosferi planeta velikosti Jupitra, ki kro\u017ei okoli druge zvezde. To je veljalo za pomemben korak v iskanju dokazov o \u017eivljenju na drugih svetovih.<\/p>\n<\/div>\n

Doslej je bilo odkritih okoli 300 planetov, ki kro\u017eijo okoli oddaljenih zvezd. Na \u017ealost so ti zunajson\u010dni planeti tako \u0161ibki in tako dale\u010d, da jih je izredno te\u017eko preu\u010devati. Vendar pa znanstveniki s pomo\u010djo sodobnih instrumentov postopoma za\u010denjajo izvedeti ve\u010d o teh tujih svetovih in plinih, iz katerih so sestavljene njihove atmosfere.<\/p>\n

Ogljikov dioksid je plin, ki ga rastline izlo\u010dajo pono\u010di in ga uporabljajo za rast. \u017divali in ljudje ga izdihujejo vsakih nekaj sekund. Kot eden od glavnih toplogrednih plinov zadr\u017euje toploto in prispeva k segrevanju planeta. Ogljik je tudi osnova tako imenovanih organskih spojin, ki sodijo med gradnike \u017eivljenja. Zdaj je teleskop Hubble pokazal, da lahko na oddaljenih planetih zaznamo ogljikov dioksid in ocenimo, koliko ga je prisotnega. To je velik napredek v dolgoro\u010dnih prizadevanjih za ugotavljanje, iz \u010desa so sestavljeni ti svetovi in ali bi lahko podpirali \u017eivljenje.<\/p>\n

Planet, imenovan HD 189733b, je preve\u010d vro\u010d za \u017eivljenje. Kljub temu je primeren za opazovanje, saj se enkrat na 2,2 dneva skrije za svojo spremljevalno zvezdo. Z raziskovanjem rednih sprememb svetlobe, ki dose\u017ee Zemljo, lahko znanstveniki analizirajo planetovo atmosfero. \u017de so odkrili vodno paro in metan. Nove opazovanja s teleskopom Hubble dokazujejo, da je mogo\u010de na planetih, ki kro\u017eijo okoli drugih zvezd, izmeriti osnovne kemijske sestavine, potrebne za \u017eivljenje.<\/p>","protected":false},"excerpt":{"rendered":"
