Ziemia jest jedynym znanym nam miejscem, w kt\u00f3rym istnieje \u017cycie. Co sprawia, \u017ce jest ona tak wyj\u0105tkowa? Jednym z kluczowych czynnik\u00f3w jest obecno\u015b\u0107 wody w stanie ciek\u0142ym. Wydaje si\u0119, \u017ce \u017cycie na Ziemi powsta\u0142o w ka\u0142u\u017cach lub morzach. \u017badna forma \u017cycia na naszej planecie nie mo\u017ce przetrwa\u0107 bez wody.<\/p>\n<\/div>\n

Ziemia jest jedynym miejscem w naszym Uk\u0142adzie S\u0142onecznym, na kt\u00f3rego powierzchni znajduj\u0105 si\u0119 rozleg\u0142e oceany. Wynika to z faktu, \u017ce znajduje si\u0119 ona w strefie \u2018Goldilocks\u2019.<\/p>\n

Wenus znajduje si\u0119 zbyt blisko S\u0142o\u0144ca i jest zbyt gor\u0105ca. Mars jest zbyt daleko i zbyt zimny. Ziemia znajduje si\u0119 w idealnej odleg\u0142o\u015bci i ma odpowiedni\u0105 temperatur\u0119.<\/p>\n

Czy mog\u0105 istnie\u0107 \u2018Ziemie\u2019 kr\u0105\u017c\u0105ce wok\u00f3\u0142 innych gwiazd? Jak mogliby\u015bmy je rozpozna\u0107? Pierwsz\u0105 rzecz\u0105, kt\u00f3r\u0105 nale\u017cy zrobi\u0107, jest zmierzenie, jak gor\u0105ca lub zimna jest dana planeta. Powinny te\u017c istnie\u0107 dowody na to, \u017ce wyst\u0119puje tam woda w du\u017cych ilo\u015bciach.<\/p>\n

Nast\u0119pnie musimy poszuka\u0107 gaz\u00f3w, takich jak tlen i metan. Gazy te s\u0105 uwalniane do powietrza przez organizmy \u017cywe.<\/p>\n

W ramach przysz\u0142ych misji b\u0119dzie prowadzone poszukiwanie tych \u2018biomarker\u00f3w\u2019 w tysi\u0105cach uk\u0142ad\u00f3w gwiezdno-planetarnych. Chocia\u017c misje te nie b\u0119d\u0105 bezpo\u015brednio wykrywa\u0107 tlenu, b\u0119d\u0105 \u2018widzie\u0107\u2019 ozon, kt\u00f3ry jest jedn\u0105 z form tlenu. B\u0119d\u0105 r\u00f3wnie\u017c wykrywa\u0107 dwutlenek w\u0119gla, wod\u0119, a w niekt\u00f3rych przypadkach \u2013 metan.<\/p>","protected":false},"excerpt":{"rendered":"
