Kas Marsil on elu? Kindlasti ei oota keegi, et sealt leitaks arukaid marslasi, nagu neid n\u00e4idati filmis \u2018Maailmade s\u00f5da\u2019. Siiski viitavad ESA Mars Expressi orbitaalaparaadi ja maapealsete observatooriumide tulemused sellele, et punasel planeedil v\u00f5ivad maa all peituda lihtsad eluvormid.<\/p>\n<\/div>\n

Selle m\u00f5istatuse lahenduseks on metaan \u2013 gaas, mida Maal kasutatakse toiduvalmistamiseks ja k\u00fctmiseks. Suure osa meie atmosf\u00e4\u00e4ris leiduvast metaanist eraldavad arenenud eluvormid, n\u00e4iteks toitu seedivad veised. Siiski on ka teisi viise metaani tekkeks, n\u00e4iteks vulkaaniline tegevus.<\/p>\n

Metaan avastati Marsil 2003. aastal. Kuna see gaas laguneb kergesti, eeldati, et selle p\u00fcsivusaeg Marsi atmosf\u00e4\u00e4ris on umbes 300 aastat. T\u00e4psem anal\u00fc\u00fcs n\u00e4itas, et metaan oli tegelikult kontsentreerunud kolmes piirkonnas. See n\u00e4itas, et gaasi vabanes just sel hetkel ning me tuvastasime selle enne, kui see oli j\u00f5udnud \u00fcle kogu planeedi levida.<\/p>\n

Siis pakkus Mars veel \u00fche \u00fcllatuse. Selle asemel, et kaduda 300 aasta jooksul, oli metaan 2006. aasta alguseks peaaegu t\u00e4ielikult kadunud. Midagi eemaldas seda atmosf\u00e4\u00e4rist 600 korda kiiremini kui oodatud. ESA teadlased kahtlustavad, et s\u00fc\u00fcdi v\u00f5ib olla planeedi pind. Kas metaan j\u00e4\u00e4b tolmu sisse kinni v\u00f5i h\u00e4vitavad seda v\u00e4ga reaktiivsed kemikaalid, nagu vesinikperoksiid. See v\u00f5ib t\u00e4hendada, et planeedi pind on elule palju vaenulikum kui varem arvatud. Kui see on nii, peavad tulevased uurijad puurima s\u00fcgavale maa alla, et otsida m\u00e4rke minevikust v\u00f5i praegusest elust.<\/p>","protected":false},"excerpt":{"rendered":"
