Selv med de st\u00f8rste teleskoper er det meget sv\u00e6rt at se mange detaljer p\u00e5 Mars. I slutningen af 1800-tallet troede nogle forskere, at de kunne se lige linjer, der krydsede planetens overflade. Disse linjer forbandt gr\u00f8nne omr\u00e5der, der s\u00e5 ud, som om de var d\u00e6kket af planter. Disse forskere mente, at de lige linjer var kanaler, som marsboerne havde bygget for at f\u00f8re vand til deres afgr\u00f8der.<\/p>\n<\/div>\n

Billeder fra rumfart\u00f8jer har vist, at disse kanaler ikke findes. Der er ingen tegn p\u00e5 liv \u2013 hverken planter eller intelligente marsboere \u2013 p\u00e5 planeten. Vi ved nu, at Mars er en meget kold og t\u00f8r planet, hvor der ikke kan findes flydende vand p\u00e5 overfladen. Der findes dog store omr\u00e5der med vandis ved polkapperne. Der er ogs\u00e5 meget is i den frosne jord \u2013 ligesom i permafrostomr\u00e5derne i det nordlige Canada og Rusland.<\/p>\n

Store, udt\u00f8rrede flodlejer vidner ogs\u00e5 om, at der engang var store m\u00e6ngder rindende vand p\u00e5 overfladen. Nylige resultater fra Mars Express og andre rumfart\u00f8jer tyder p\u00e5, at der muligvis findes flydende vand dybt under jorden. Hvis Mars engang var varmere og fugtigere, kan der have opst\u00e5et liv p\u00e5 den r\u00f8de planet. Enkle livsformer, s\u00e5som bakterier, kan stadig findes under den frosne overflade.<\/p>\n

I 1996 meddelte en gruppe forskere verden, at de havde fundet beviser p\u00e5 bakterier inde i en meteorit, der stammede fra Mars. Denne teori nyder dog ikke stor tilslutning blandt de fleste andre forskere. Hvis der i fremtiden findes liv p\u00e5 Mars, ville det v\u00e6re det f\u00f8rste bevis p\u00e5, at vi ikke er alene i universet.<\/p>","protected":false},"excerpt":{"rendered":"
