Jupiter, den st\u00f8rste planeten i solsystemet, best\u00e5r hovedsakelig av gassene hydrogen og helium. Det er funnet sv\u00e6rt sm\u00e5 mengder vann i planetens \u00f8vre atmosf\u00e6re, men inntil n\u00e5 var ingen sikre p\u00e5 hvor dette vannet kom fra. Svaret p\u00e5 dette langvarige mysteriet er gitt av ESAs romobservatorium Herschel, det mest f\u00f8lsomme infrar\u00f8de teleskopet som noensinne er skutt opp. Herschel har funnet avgj\u00f8rende bevis for at vannet ble f\u00f8rt til planeten ved flere kometnedslag i juli 1994!<\/p>\n

Kollisjoner med innkommende kosmisk avfall utgj\u00f8r en kontinuerlig trussel mot planetene i solsystemet, inkludert Jorden. Imidlertid har forskerne faktisk kun observert f\u00e5 slike nedslag. Den f\u00f8rste direkte observasjonen av en slik hendelse fant sted ved Jupiter for 19 \u00e5r siden. Astronomene s\u00e5 forbl\u00f8ffet p\u00e5 da 21 deler av kometen Shoemaker-Levy 9 styrtet inn i planetens \u00f8vre atmosf\u00e6re og eksploderte.<\/p>\n

ESAs infrar\u00f8de romobservatorium, som ble skutt opp i 1995, var det f\u00f8rste som oppdaget og unders\u00f8kte vann i Jupiters \u00f8vre atmosf\u00e6re. Forskerne kunne utelukke en intern kilde, for eksempel vann som steg opp fra dypet. Men hvis vannet kom utenfra, hvor kom det da fra?<\/p>\n

Det var utbredt spekulasjon om at kometen Shoemaker-Levy 9 kunne ha v\u00e6rt kilden til dette vannet, men det manglet direkte bevis. N\u00e5 har Herschels f\u00f8lsomme infrar\u00f8de \u00ab\u00f8yne\u00bb l\u00f8st mysteriet. Romobservatoriet har funnet 2\u20133 ganger mer vann p\u00e5 Jupiters s\u00f8rlige halvkule enn p\u00e5 den nordlige. Sporene av vann finnes kun i store h\u00f8yder, og det meste er konsentrert rundt stedene der kometene traff i 1994.<\/p>\n

ESAs JUICE-oppdrag, som etter planen skal skytes opp mot den gigantiske planeten i 2022, vil gi enda mer detaljerte observasjoner av gassene som utgj\u00f8r Jupiters enorme atmosf\u00e6re.<\/p>","protected":false},"excerpt":{"rendered":"
