Hubble-rumteleskopet (HST) er det mest ber\u00f8mte \u2013 og sandsynligvis mest succesrige \u2013 rumobservatorium, der nogensinde er sendt ud i rummet. Det 11 ton tunge teleskop blev i april 1990 bragt i en bane 570 km over Jorden af rumf\u00e6rgen. HST kredser om vores planet hvert 96. minut og har indtil videre tilbagelagt omkring 5 milliarder km.<\/p>\n<\/div>\n

Hubble har sendt en enorm m\u00e6ngde videnskabelige data og utroligt detaljerede billeder af alle former for himmellegemer tilbage. Indtil efter\u00e5ret 2009 havde teleskopet foretaget n\u00e6sten 900.000 observationer og taget over 570.000 billeder af mere end 29.000 himmellegemer.<\/p>\n

HST er opkaldt efter Edwin Hubble (1889\u20131953), en af de store pionerer inden for moderne astronomi. Kernen i teleskopet udg\u00f8res af et 2,4 m stort hovedspejl og fem videnskabelige instrumenter, der unders\u00f8ger universet i infrar\u00f8dt, synligt eller ultraviolet lys. Lyset, der opfanges af hovedspejlet, reflekteres over p\u00e5 et mindre spejl og sendes derefter videre til instrumenterne. Dataene sendes derefter til Jorden via en rel\u00e6satellit.<\/p>\n

Observatoriet forsynes med str\u00f8m fra to store solcellepaneler (2,6 \u00d7 7,1 m). Der anvendes finstyringssensorer til at l\u00e5se fast p\u00e5 ledestjerner. Dette sikrer den ekstremt h\u00f8je pegepr\u00e6cision, der er n\u00f8dvendig for at kunne foretage meget n\u00f8jagtige observationer.<\/p>\n

Hubble er det eneste teleskop, der nogensinde er konstrueret med henblik p\u00e5 at blive vedligeholdt i rummet af astronauter, s\u00e5 gamle instrumenter kan udskiftes. Dette viste sig at v\u00e6re af uvurderlig betydning, da de f\u00f8rste billeder var sl\u00f8rede, og der i 1993 m\u00e5tte installeres et specielt optisk system for at afhj\u00e6lpe problemet. Der har v\u00e6ret fem vedligeholdelsesmissioner, hvoraf den sidste fandt sted i maj 2009. Teleskopet forventes at forts\u00e6tte driften indtil 2014.<\/p>","protected":false},"excerpt":{"rendered":"
