<prompt> Fingqa isihloko: Ngokokuqala ngqá ngemva kweminyaka eyishumi, izazi zezinkanyezi ziye zathola imithala emincane ezungeza iMilky Way - ingqikithi eyisishiyagalolunye engenakuqhathaniswa. Zisukela ebangeni eliqhele ngeminyaka yokukhanya engu-95 000 kuya kweyisigidi esingu-1,2 futhi ngayinye iqukethe izinkanyezi ezimbalwa kakhulu kunomthala wethu. Nokho, okubaluleke kakhulu, imithala emincane ingase isize ekuhloleni imibono ephathelene nendaba emnyama futhi mhlawumbe isisondeze ngokwengeziwe ekutholeni lezi zinhlayiya ezingabonakali kalula. Hambisa isilayidi ngezansi ukuze ubone isithombe sesibhakabhaka esiseningizimu ngaphambi nangemva kokungezwa kwemithala emisha emincane. Izazi zezinkanyezi ziye zathola imithala emisha engu - 9 emincane ezungeza iMilky Way. Ziyizinto zokuqala ezitholakalayo ezizungeza umbuthano wethu wesibhakabhaka eminyakeni engaphezu kweyishumi. Lesi sithombe sibonisa amafu aziwa ngaphambili aseMagellanic kanye nezinkanyezi eziyisithupha kweziyisishiyagalolunye ezisanda kutholakala ngenhla kweParanal Observatory eChile. Lolu cwaningo lwenziwa iqembu lezazi zezinkanyezi eNyuvesi yaseCambridge lisebenzisa imininingwane evela kuyiDark Energy Survey, okuwumsebenzi weminyaka emihlanu wokuthwebula izithombe zesibhakabhaka esiseningizimu ngokuningiliziwe. Le mibuthano yezinkanyezi emincane eyisishiyagalolunye yabonwa esibhakabhakeni sasebusuku engxenyeni eseningizimu yomhlaba, eduze kwe-Large and Small Magellanic Cloud, okuyimithala emincane emikhulu emzileni weMilky Way. Izazi zezinkanyezi ziye zathola ukuthi indandatho eyinqaba yezinkanyezi ezikude kungenzeka empeleni iyingxenye yomthala wethu, ewenza ube mkhulu ngamaphesenti angu-50 ngobubanzi beminyaka yokukhanya engu-150 000. Lokhu kusekelwe ekuhlaziyeni kabusha indandatho ekude ezungeze umthala wethu, izazi zezinkanyezi ezicabanga ukuthi manje empeleni iyingxenye yawo, futhi kungenzeka yaphazanyiswa eminye imithala emincane. Ithimba lososayensi abavela eRensselaer Polytechnic Institute eNew York lafunda i - Monoceros Ring, okuyi - filament ende enjengendandatho yezinkanyezi ezungeza umthala wethu kathathu. Ukutholakala kwamasathelayithi amaningi kangaka endaweni encane kangaka esibhakabhakeni kwakungalindelekile ngokuphelele, kusho uDkt Sergey Koposov waseCambridges Institute of Astronomy, umbhali oyinhloko walolu cwaningo. Angizange ngikholwe engikubonayo. Lezi zinto ezisanda kutholakala zimnyama izikhathi eziyizinkulungwane eziyinkulungwane kuneNdlela Yezulu, futhi zincane izikhathi eziyizigidi...  <response>: Izazi zezinkanyezi zaseYunivesithi yaseCambridge zithole imithala emisha eyisishiyagalolunye emincane ezungeza iMilky Way. Ziyizinto zokuqala ezitholakale zizungeza iMilky Way eminyakeni eyishumi kusukela kwatholakala eziningi ngo - 2005 nango - 2006. Kunezinkanyezi eziyisishiyagalolunye esewonke, eziqhele ngezinkulungwane ezingu-95 000 kuya kwezigidi ezingu-1,2 zeminyaka-kukhanya. Ngamunye wawo usuntekenteke izikhathi eziyizigidi eziyinkulungwane futhi unesisindo esiphansi izikhathi eziyisigidi kunomthala wethu, futhi uqukethe izinkanyezi ezimbalwa kakhulu. Kodwa kucatshangwa ukuthi zingama-99 endaba emnyama - engasiza ekuqinisekiseni imibono yokuba khona kwayo endaweni yonke.
