Selv med de st\u00f8rste teleskopene er det sv\u00e6rt vanskelig \u00e5 se mange detaljer p\u00e5 Mars. P\u00e5 slutten av 1800-tallet trodde noen forskere at de kunne se rette linjer som krysset planetens overflate. Disse linjene forbant gr\u00f8nnaktige omr\u00e5der som s\u00e5 ut som om de var dekket av planter. Disse forskerne trodde at de rette linjene var kanaler bygget av marsboere for \u00e5 f\u00f8re vann til avlingene sine.<\/p>\n<\/div>\n

Bilder fra romfart\u00f8y har vist at disse kanalene ikke eksisterer. Det er ingen tegn til liv \u2013 verken planter eller intelligente marsboere \u2013 p\u00e5 planeten. Vi vet n\u00e5 at Mars er en sv\u00e6rt kald og t\u00f8rr planet, der flytende vann ikke kan eksistere p\u00e5 overflaten. Det finnes imidlertid store omr\u00e5der med vannis ved polkapperne. Det er ogs\u00e5 mye is i den frosne jorden \u2013 omtrent som i permafrostomr\u00e5dene i Nord-Canada og Russland.<\/p>\n

Store, utt\u00f8rkede elveleier tyder ogs\u00e5 p\u00e5 at det en gang var mye rennende vann p\u00e5 overflaten. Nye funn fra Mars Express og andre romfart\u00f8yer tyder p\u00e5 at det kan finnes flytende vann dypt under bakken. Hvis Mars en gang var varmere og fuktigere, kan det ha oppst\u00e5tt liv p\u00e5 den r\u00f8de planeten. Enkelt liv, som for eksempel bakterier, kan fortsatt finnes under den frosne overflaten.<\/p>\n

I 1996 fortalte en gruppe forskere verden at de hadde funnet bevis p\u00e5 bakterier inne i en meteoritt som stammet fra Mars. Denne teorien er imidlertid ikke s\u00e6rlig popul\u00e6r blant de fleste andre forskere. Hvis det i fremtiden blir funnet liv p\u00e5 Mars, ville det v\u00e6re det f\u00f8rste beviset p\u00e5 at vi ikke er alene i universet.<\/p>","protected":false},"excerpt":{"rendered":"
