Jupiter, solsystemets st\u00f8rste planet, best\u00e5r hovedsageligt af gasserne brint og helium. Der er fundet sm\u00e5 m\u00e6ngder vand i planetens \u00f8vre atmosf\u00e6re, men indtil nu har ingen v\u00e6ret sikker p\u00e5, hvor dette vand stammer fra. Svaret p\u00e5 dette mange\u00e5rige mysterium er blevet leveret af ESA\u2019s rumobservatorium Herschel, det mest f\u00f8lsomme infrar\u00f8de teleskop, der nogensinde er sendt op. Herschel har fundet afg\u00f8rende beviser for, at vandet blev bragt til planeten ved flere kometnedslag i juli 1994!<\/p>\n

Kollisioner med indkommende kosmisk affald udg\u00f8r en konstant trussel mod planeterne i solsystemet, herunder Jorden. Imidlertid har forskerne kun observeret f\u00e5 s\u00e5danne nedslag. Den f\u00f8rste direkte observation af en s\u00e5dan begivenhed fandt sted ved Jupiter for 19 \u00e5r siden. Astronomerne s\u00e5 forbl\u00f8ffet til, da 21 stykker af kometen Shoemaker-Levy 9 styrtede ned i planetens \u00f8vre atmosf\u00e6re og eksploderede.<\/p>\n

Vand i Jupiters atmosf\u00e6re<\/figcaption><\/figure>\n

ESA\u2019s infrar\u00f8de rumobservatorium, der blev opsendt i 1995, var det f\u00f8rste til at p\u00e5vise og unders\u00f8ge vand i Jupiters \u00f8vre atmosf\u00e6re. Forskerne kunne udelukke en intern kilde, s\u00e5som vand, der steg op fra dybere lag. Men hvis vandet kom udefra, hvor stammede det s\u00e5 fra?<\/p>\n

Der var bred enighed om, at kometen Shoemaker-Levy 9 muligvis var kilden til dette vand, men der manglede direkte beviser. Nu har Herschels f\u00f8lsomme infrar\u00f8de \u00f8jne l\u00f8st mysteriet. Rumobservatoriet har fundet 2-3 gange mere vand p\u00e5 Jupiters sydlige halvkugle end p\u00e5 den nordlige. Sporene af vand findes kun i store h\u00f8jder, og det meste er koncentreret omkring de steder, hvor kometen ramte i 1994.<\/p>\n

ESA\u2019s JUICE-mission, som efter planen skal sendes af sted mod den gigantiske planet i 2022, vil foretage endnu mere detaljerede observationer af de gasser, der udg\u00f8r Jupiters enorme atmosf\u00e6re.<\/p>","protected":false},"excerpt":{"rendered":"
