<prompt> I-Eclipse: Izixuku zezinkanyezi eziyindilinga zingabalwa phakathi kwezinto ezindala kunazo zonke eMilky Way, okwenza kube nomkhawulo ophansi eminyakeni yabo ye-Milky Way. Iminyaka yezinkanyezi ngazinye eMilky Way ingalinganiswa ngokulinganisa ubuningi bezinto ezinemisebe ezisebenza isikhathi eside njenge-thorium-232 ne-uranium-238, bese kuqhathaniswa imiphumela nokulinganiswa kwenani lazo lokuqala, inqubo ebizwa nge-nucleocosmochronology. Le miphumela iveza amanani eminyaka ayizigidi eziyizinkulungwane eziyi-12.5 3 ye-CS 31082-001 kanye ne-13.8 4 iminyaka ye-BD 17 3248. Uma i-white star isakhiwe, iqala ukupholisa ngemisebe futhi izinga lokushisa elingaphezulu lihlala liwela. Ngokulinganisa amazinga okushisa alezi zinkanyezi ezipholile kunazo zonke ezimhlophe futhi uziqhathanise nobudala bazo obulindelekile, kungalinganiswa izinga lokuqala lokushisa. Ngale ndlela yokuthola izinkanyezi eziyindilinga eMilky Way kungalinganiswa ngeminyaka em  <response>: Iminyaka eyizigidi eziyizinkulungwane ezingu-13.2
