Ali obstaja \u017eivljenje na Marsu? Seveda nih\u010de ne pri\u010dakuje, da bi na\u0161li inteligentne Mar\u010dane, kakr\u0161ne smo videli v filmu \u2018Vojna svetov\u2019. Vendar pa rezultati sonda Mars Express agencije ESA in opazovalnic na Zemlji ka\u017eejo, da bi se na rde\u010dem planetu pod zemljo lahko skrivale preproste oblike \u017eivljenja.<\/p>\n<\/div>\n

Klju\u010d do razre\u0161itve te uganke je metan, plin, ki se na Zemlji uporablja za kuhanje in ogrevanje. Ve\u010dino metana v na\u0161i atmosferi izpu\u0161\u010dajo vi\u0161je oblike \u017eivljenja, na primer govedo med prebavo hrane. Vendar pa obstajajo tudi drugi na\u010dini nastajanja metana, na primer vulkanska dejavnost.<\/p>\n

Metan je bil na Marsu odkrit leta 2003. Ker se ta plin zlahka razgradi, so pri\u010dakovali, da bo njegova \u017eivljenjska doba v marsovski atmosferi zna\u0161ala okoli 300 let. Natan\u010dnej\u0161a analiza je pokazala, da se je metan dejansko koncentriral v treh regijah. To je nakazovalo, da se je spro\u0161\u010dal prav v tem trenutku, mi pa smo ga zaznavali, \u0161e preden se je uspel raz\u0161iriti po planetu.<\/p>\n

Nato je Mars pripravil \u0161e eno presene\u010denje. Namesto da bi metan izginil v 300 letih, se je do za\u010detka leta 2006 skoraj v celoti izgubil. Nekaj ga je iz atmosfere odstranjevalo 600-krat hitreje, kot je bilo pri\u010dakovano. Znanstveniki iz ESA sumijo, da je za to morda kriva povr\u0161ina planeta. Metan se bodisi zadr\u017euje v prahu bodisi ga uni\u010dujejo visoko reaktivne kemikalije, kot je vodikov peroksid. To bi lahko pomenilo, da je povr\u0161ina veliko bolj neprimerna za \u017eivljenje, kot so sprva menili. \u010ce je tako, bodo morali prihodnji raziskovalci vrtati globoko pod zemljo, da bi poiskali znake preteklega ali sedanjega \u017eivljenja.<\/p>","protected":false},"excerpt":{"rendered":"
