Archeops

Archeops bụ ngwá ọrụ balloon a raara nye ịtụle Cosmic microwave background (CMB) okpomọkụ anisotropies. Nnyocha nke radieshon a dị mkpa iji nweta ozi ziri ezi banyere evolushọn nke Eluigwe na Ala: njupụta, Hubble constant, afọ nke eluigwe na ala, wdg. Iji mezuo ebumnuche a, a na-eji ngwaọrụ ndị jụrụ oyi na 100mK okpomọkụ etinye na anya nke onyokomita na-ekpo ọkụ. Iji zere nsogbu ikuku, a na-etinye ngwaọrụ ahụ dum na gondola n'okpuru balloon helium nke ruru kilomita 40 n'ịdị elu. 

Archeops nwere bands anọ na mpaghara millimeter (143, 217, 353 na 545 GHz) na mkpebi dị elu (ihe dị ka 15 arcminutes) iji gbochie obere anisotropy scales, yana nnukwu igwe mkpuchi (30%) iji belata ọdịiche dị na mbara igwe.
