UGiada uyisiqoqo senkanyezi esiseduze esiseduze nathi. Kuyiminyaka eyi-153 elula, ekumemezelweni kweTaurus, ukuze izinkanyezi eziningana eziqhakazile zibonakale esweni elinqunu kuzo zombili izitho zangasese zomhlaba. Ngokusho kososayensi, iGiada yakha eminyakeni engaphezu kwezigidi ezingama-600 eyedlule futhi yathola inqwaba yokonga okungaba ngu-400. Le clas yawela i-lens ye-European Space Prove Gaia - Idivaysi eholayo yokubukwa kwezinkanyezi nokulandela izikhundla ezinembile nokukhanya kwesethi yezinkanyezi.
Leli thuluzi libhekwe eGiada cishe amakhandlela ayikhulu, ahlala isikhala cishe iminyaka engama-60 kububanzi, futhi ngaphezu kwezinkanyezi esele zishiye isifunda esisenkabeni yeqoqo. Ukwahlulela ngokunyakaza kwabo, uGiada uyafa, abhubhisa ngaphansi kwesenzo somuntu omkhulu, kodwa manje umakhelwane ongaziwa. Mayelana nalolu Jereza JeraBkova (Tereza Jerabkova) nozakwabo babikwe ku-athikili entsha eshicilelwe kumagazini we-Astronomy & Astrophysics. Ukutholwa kubuye kuchaze ukukhishwa kwabezindaba, i-ESA ejwayelekile.
AmaCluster wenkanyezi akude kakhulu. Ukusebenzisana okuyinkimbinkimbi kwamandla akwa-Graverational emavesini anjalo izinkanyezi kuphonsa abanye babo eduze nasemaphethelweni, futhi ngaphansi kwesenzo samandla omthala engxenyeni yomthala, bashiya phambili. Ukugeleza okude nokuncane kwe- "Tidal Tailings" kudonswa ngaphandle kokuqongelela. Lapho eselandele izinkanyezi eziseduzane nase-Ayad, iGaia Telescope yasiza ukwaba labo abahamba kanye nokuqongelela, ngakho-ke, kuvela kuyo kuyo.
Ukuhlonza ngisho nalezo zinkanyezi eziye zashiya i-giada futhi zazingakwazi ukungena ohlwini oluphelele ngenxa yebanga elide noma umehluko ngejubane lokunyakaza, ososayensi baqhuba ukumbumbuluzwa kwekhompyutha. Lokhu kwenze kwaba nokwenzeka ukubikezela ukuthi izinkanyezi kufanele zifunwe kuphi kwimininingwane ye-telescope, futhi zikhombe izinkulungwane zamaLumidies angelokuhlanganiswa kwalo. Namuhla bakhipha imisila emibili emide kunesikhathi seminyaka engama-2,600.
Ngasikhathi sinye, inani lezinkanyezi kwelinye lama-tailings alizange lilingane nezibikezelo zamamodeli. Lokhu, ngokusho kososayensi, kubonisa ubukhona behlobo oluthile lwento enkulu, ukuheha okubhubhisa kakhulu uGiada. Izibalo zikhombisa ukuthi inqwaba yayo kufanele ifinyelele ezigidini eziyi-10. Kodwa-ke, bekungenzeki ukuthola into yababhuli bezazi zezinkanyezi. Kungaba ifu legesi, kepha akukho lutho olufanele endaweni oyifunayo. Mhlawumbe sisebenzelana nento emnyama nge-clot, engazivezi nganoma iyiphi indlela, ngaphezu kokuheha kwabo.
