Forskare har funnit bevis f\u00f6r att det finns flytande vatten p\u00e5 Mars.<\/p>\n

En ny uppsats med titeln Radarbevis f\u00f6r flytande vatten under glaci\u00e4ren p\u00e5 Mars<\/a>\u00a0publicerades p\u00e5 Science. Artikeln tyder p\u00e5 att flytande vatten kan finnas under ett lager av is vid Mars sydpol.<\/p>\n

\"Vatten anses vara en av de grundl\u00e4ggande f\u00f6ruts\u00e4ttningarna f\u00f6r liv. Det h\u00e4r \u00e4r den f\u00f6rsta stabila kroppen med flytande vatten som n\u00e5gonsin hittats p\u00e5 Mars, och den skulle kunna betraktas som en potentiell livsmilj\u00f6\", f\u00f6rklarar Roberto Orosei, en ledande forskare vid Institute of Radioastronomy i Italien som analyserade data.<\/p>\n

Denna uppt\u00e4ckt \u00e4r s\u00e4rskilt fantastisk eftersom det finns underjordiska sj\u00f6ar som denna n\u00e4ra jordens poler, fr\u00e4mst p\u00e5 Gr\u00f6nland och Antarktis. En av dessa sj\u00f6ar, den subglaciala sj\u00f6n Whillans i Antarktis, har inte funnits p\u00e5 jordytan p\u00e5 miljontals \u00e5r. Och nyligen hittade forskare bakterier som fortfarande lever d\u00e4r i fullst\u00e4ndig isolering.<\/p>\n

Vostoksj\u00f6n, som ligger under kilometervis av is, har varit ist\u00e4ckt i minst 15 miljoner \u00e5r. Analyser av livsformerna tyder p\u00e5 att Vostoksj\u00f6n kan hysa ett unikt ekosystem som bygger p\u00e5 kemikalier i stenar ist\u00e4llet f\u00f6r solljus och som har levt isolerat i hundratusentals \u00e5r.<\/p>\n

Forskare har ocks\u00e5 hittat mikroorganismer under jord i gruvor. Dessa mikroorganismer \u00e4r sl\u00e4kt med ur\u00e5ldriga arter som en g\u00e5ng levde i vattenrika milj\u00f6er. S\u00e5dana migrationer \u00f6kar m\u00f6jligheten att samma sak h\u00e4nder p\u00e5 Mars - n\u00e4r vattnet drar sig tillbaka flyttar livet djupare ner under jorden.<\/p>\n

\"F\u00f6lj vattnet\"<\/a> har varit ett av de viktigaste m\u00e5len f\u00f6r NASA:s Marsprogram. Vatten \u00e4r f\u00f6r n\u00e4rvarande drivkraften bakom NASA:s utforskning av det yttre solsystemet. D\u00e4r oceanv\u00e4rldar - som Jupiters m\u00e5ne Europa - har potential att st\u00f6dja liv. \u00c4ven protoplaneter som Ceres kan f\u00f6rklara hur vatten lagras i steniga \"hinkar\" som transporterar vatten \u00f6ver hela solsystemet.<\/p>","protected":false},"excerpt":{"rendered":"
