Hayi, uninzi lwabavumisi ngeenkwenkwezi nabo nabo nabo babesazi ukuba indlela ye-lelky yayigobile, phantse yonke le mizekeliso, le nyaniso yenziwa ngokulula okanye engabikho kwidatha echanekileyo. Nangona kunjalo, izazinzulu zaseMelika kwiYunivesithi yaseVirgin idale ububonelo olutsha ekusebenziseni imeko yemicimbi yokwenyani. Ngokutsho kwePortal yoMbutho ngoMdibaniso, lo msebenzi yinxalenye yoqwalaselo lwasezulwini lwe "Slianovysky" (SDSS). Ukubonwa kobume baqala kuboniswa kwisakhelo sentlanganiso ye-237 yoluntu lwaseMelika lwe-American Social (AAS).
Ubukho bokugoba kwindiza ye-Gilaxies yeSpiral ifunyenwe ixesha elide - ngaxeshanye noqwalaselo lokuqala olucacileyo lwezinto ezinjalo. Olona hlobo lubalulekileyo ngala maza awaziwa ngokunyaniseka. Eyona modeli ingqiqweni yendlela ebangela ifuthe lomnye umnyele welinye icala, eyayikufuphi kumgama omfutshane. Ukudibana okunjalo nokusebenzisana, iigalaxi zisuswa omnye komnye okanye zibe sesatellite, kwaye iinkwenkwezi ngaphakathi kubo zihamba kwi-trajectories etshintshileyo ixesha elide. Indlela yeMilky yafezekiswa ne-pertingbator yokuzola kwiminyaka emithathu eyadlulayo - kutshanje kwimigangatho yendalo.
Ukubona igorha elinje kumlonde wakhe, izazinzulu kwafuneka zisebenze kakuhle. Iiseti ezimbini zedatha zasetyenziswa ngaxeshanye: ukusuka kwi-Apogee Appervatory e-Apochi-Point eNew Mexico (i-USA) kunye neziphumo ze-telescope ye-telescope. Ukuboniswa okubonakalayo kweGalaxy ye-Galaxy ayisiyo ividiyo entle. Le yimveliso ethe ngqo kwiQhatshwa leQhatshwa leMildional Way, owona msebenzi unzima ukufumanisa indawo ngqo kwindawo yamakhulu amawaka eenkwenkwezi.
Njengenxalenye ye-Apogee, iteleskopu ene-2.5 -ibrike yesipili semitha phantse iminyaka elishumi ifundwe i-spectra ye-100 yamawaka eendlela ezibomvu zeMilky Way. Oku akuvunyelwe kungekuphela nje ukumisela ubume babo, kodwa nokumisela iminyaka yeenkwenkwezi, kunye neempawu ezithile zentshukumo. Emva koko le datha idityaniswe nolwazi olufunyenwe zizixhobo ze-Gaia. Enkosi kuye, i-AstronomersronomersOnoamers ikwazi ngqo ukusuka kumgama ukusuka emhlabeni ukuya kwizigidi zeenkwenkwezi. Ngenxa yothelekiso, bekunokwenzeka ukuba yenze imephu yendawo yesikhundla se-luminaire kwaye ubone ukuba bathandabuza njani, ngokungathi ngamaza kangangesiko.
