P\u0103m\u00e2ntul este singurul loc pe care \u00eel cunoa\u0219tem care sus\u021bine via\u021ba. Ce \u00eel face at\u00e2t de special? Un factor cheie este prezen\u021ba apei \u00een stare lichid\u0103. Via\u021ba pe P\u0103m\u00e2nt pare s\u0103 fi luat na\u0219tere \u00een b\u0103l\u021bi sau m\u0103ri. Nicio form\u0103 de via\u021b\u0103 de pe planeta noastr\u0103 nu poate supravie\u021bui f\u0103r\u0103 ap\u0103.<\/p>\n<\/div>\n

P\u0103m\u00e2ntul este singurul loc din Sistemul nostru Solar care are oceane \u00eentinse la suprafa\u021b\u0103. Acest lucru se datoreaz\u0103 faptului c\u0103 se afl\u0103 \u00een zona \u2018Goldilocks\u2019.<\/p>\n

Venus este prea aproape de Soare \u0219i prea fierbinte. Marte este prea departe \u0219i prea rece. P\u0103m\u00e2ntul se afl\u0103 la distan\u021ba potrivit\u0103 \u0219i are temperatura potrivit\u0103.<\/p>\n

Ar putea exista \u2018P\u0103m\u00e2nturi\u2019 care orbiteaz\u0103 \u00een jurul altor stele? Cum le-am putea recunoa\u0219te? Primul lucru pe care trebuie s\u0103-l facem este s\u0103 m\u0103sur\u0103m c\u00e2t de cald\u0103 sau de rece este o planet\u0103. De asemenea, ar trebui s\u0103 existe dovezi c\u0103 apa este prezent\u0103 \u00een cantit\u0103\u021bi mari.<\/p>\n

Atunci trebuie s\u0103 c\u0103ut\u0103m gaze precum oxigenul \u0219i metanul. Aceste gaze sunt eliberate \u00een aer de c\u0103tre fiin\u021bele vii.<\/p>\n

Misiunile viitoare vor c\u0103uta ace\u0219ti \u2018biomarkeri\u2019 \u00een mii de sisteme stelare. De\u0219i nu vor detecta oxigenul \u00een mod direct, vor \u2018vedea\u2019 ozonul, o form\u0103 a oxigenului. De asemenea, vor detecta dioxidul de carbon, apa \u0219i, \u00een anumite cazuri, metanul.<\/p>","protected":false},"excerpt":{"rendered":"
