Forskere har fundet beviser for, at der findes flydende vand p\u00e5 Mars.<\/p>\n

En ny artikel med titlen Radar viser, at der er flydende vand under isen p\u00e5 Mars<\/a>\u00a0blev offentliggjort p\u00e5 Science. Artiklen antyder, at der kan v\u00e6re flydende vand under et lag af is p\u00e5 Mars' sydpol.<\/p>\n

\"Vand anses for at v\u00e6re en af de grundl\u00e6ggende foruds\u00e6tninger for liv. Dette er den f\u00f8rste stabile m\u00e6ngde flydende vand, der nogensinde er fundet p\u00e5 Mars, og det kunne betragtes som et potentielt levested,\" forklarer Roberto Orosei, en ledende forsker ved Institute of Radioastronomy i Italien, som analyserede dataene.<\/p>\n

Denne opdagelse er is\u00e6r fantastisk, fordi der findes underjordiske s\u00f8er som denne n\u00e6r Jordens poler, hovedsageligt i Gr\u00f8nland og Antarktis. En af disse s\u00f8er, den subglaciale Lake Whillans i Antarktis, har ikke v\u00e6ret p\u00e5 jordens overflade i millioner af \u00e5r. Og for nylig fandt forskere bakterier, der stadig lever der i fuldst\u00e6ndig isolation.<\/p>\n

Vostok-s\u00f8en, der ligger under kilometervis af is, har v\u00e6ret isd\u00e6kket i mindst 15 millioner \u00e5r. Analyser af livsformerne antyder, at Vostok-s\u00f8en kan rumme et unikt \u00f8kosystem baseret p\u00e5 kemikalier i klipper i stedet for sollys, der har levet isoleret i hundredtusinder af \u00e5r.<\/p>\n

Flydende vand menes at v\u00e6re tusinder af \u00e5r om at passere gennem s\u00f8en, som er p\u00e5 st\u00f8rrelse med Lake Ontario i Nordamerika.

Forskere har ogs\u00e5 fundet mikroorganismer under jorden i miner. Disse mikroorganismer er relateret til gamle arter, der engang levede i vandige milj\u00f8er. S\u00e5danne vandringer rejser muligheden for, at det samme skete p\u00e5 Mars - da vandet trak sig tilbage, flyttede livet dybere ned under jorden.<\/p>\n

De bedste billeder af vand p\u00e5 Mars<\/strong><\/h2>\n

 <\/p>\n

Du ved, at vi mener, at videnskab skal v\u00e6re visuel. Hvis du vil vise detaljer og f\u00e5 l\u00e6seren til at v\u00e6re opm\u00e6rksom i dit arbejde, er visuelle ressourcer et godt v\u00e6rkt\u00f8j.<\/p>\n

Derfor har jeg udvalgt de bedste billeder af denne nylige opdagelse.<\/p>\n

\"F\u00f8lg vandet\"<\/a> har v\u00e6ret et af de vigtigste m\u00e5l for NASA's Mars-program. Vand er i \u00f8jeblikket drivkraften bag NASA's udforskning af det ydre solsystem. Hvor havverdener - som Jupiters m\u00e5ne Europa - har potentiale til at underst\u00f8tte liv. Selv protoplaneter som Ceres kan forklare, hvordan vand opbevares i stenede \"spande\", der transporterer vand p\u00e5 tv\u00e6rs af solsystemet.<\/p>","protected":false},"excerpt":{"rendered":"
