<prompt> Fingqa isihloko: Uma ubheka inani likaphethiloli wokukhula kwezinkanyezi endaweni yonke, uma liqhathaniswa nenani lezinkanyezi, uzophawula okuthile okungajwayelekile - kufanele kube nezinkanyezi eziphindwe izikhathi eziyishumi kunalezo ezikhona. Kuyinkinga eye yadida ososayensi, kodwa manje ucwaningo luthi lunempendulo, luthi ukushisa kwamafu akhiqiza izinkanyezi kungase kuphazamise ukwakheka kwezinkanyezi. Bathi izinga lokushisa cishe lishisa kakhulu ukuba kuvunyelwe ukwakheka kwezinkanyezi ezilinganiselwe, okuholela enanini eliphansi lezinkanyezi esizibonayo emkhathini namuhla. Abacwaningi eMassachusetts Institute of Technology naseMichigan State University baye basikisela inkolelo-mbono entsha yokuntuleka kwezinkanyezi. Ngokusekelwe enanini likaphethiloli wezinkanyezi kufanele kube nenani eliphindwe izikhathi eziyishumi. Kodwa isizathu siwukuthi amazinga okushisa awenza angakwazi ukwakheka. Isithombe seHubble Ultra Deep Field sikhonjiswa lapha. Ukuze kwakheke inkanyezi, kunesidingo sokuba ifu legesi liphole ngokwanele ukuze likwazi ukuqoqa isisindo esikhulu esidingekayo ukuze kwakheke inkanyezi. Ikakhulukazi, igesi engaphakathi kwesixuku - eseduze nesikhungo sesixuku semithala - ngokuvamile iyisifunda esiyinhloko sokwakheka kwezinkanyezi. Kodwa kunenqwaba yezinkanyezi ezizalwa unyaka ngamunye kwezinye izinkanyezi, naphezu kokuningi kwaleli gesi, ngakho kumelwe ukuba kunokuthile okuvimbela igesi ukuba iphole futhi yakhe izinkanyezi. Ngenyanga edlule izazi zezinkanyezi zathola izinkanyezi ezakheka esifundeni esikude seMilky Way ezazingacatshangwa ngaphambili. Lezi zinkanyezi zabonakala esithombeni segesi yamangqamuzana esiyiminyaka - kukhanya engu - 16 000 ngaphansi kwediski eyisicaba yomthala wethu - kude kakhulu kunanoma iyiphi enye eyake yabonwa. Futhi uma kungakhiwa amaplanethi azungeze lezinkanyezi, izakhamuzi zaziyobona inkazimulo ephelele yomthala oyisiyingi ongaphezu kwazo esibhakabhakeni sasebusuku. Lokhu okutholakele okumangalisayo - okwaholwa uDkt. Denilso Camargo waseFederal University of Rio Grande do Sul ePorto Alegre, eBrazil - kuwukuphela kwesikhathi lapho kutholakala khona izinkanyezi ezakha izinkanyezi eziyingxenye yeMilky Way kude kangaka nomthala wethu. Lesi yisikhathi sokuqala izazi zezinkanyezi zithole izinkanyezi ezizalwa endaweni ekude kangaka, kusho yena...  <response>: Abacwaningi baseMassachusetts Institute of Technology naseMichigan State University baye basikisela inkolelo entsha yokuntuleka kwezinkanyezi.

Kwezinye izinqwaba zemithala izinga lokushisa liphakeme kakhulu ukuba kwakheke izinkanyezi. Futhi izimbobo ezimnyama zilawula amazinga okushisa ukuze zingapholi kakhulu.
