Kormeerayaasha Koonfurta Yurub (ESO, European Southern Observatory) ayaa ka hadlay hirgelinta mashruuc ballaaran oo lagu abuurayo khariidadda ugu weyn uguna saxsan ee saddex-geesoodka ah ee galaxykeena taariikhda.
Khariidaddan faahfaahsan, oo daboolaysa in ka badan bilyan xiddigood oo ku jira Jidka Caano, waxa la abuuray iyada oo la adeegsanayo xogta dayax gacmeedka Gaia ee ay hawada sare u dirtay Wakaaladda Hawada Yurub (ESA) sannadkii 2013kii. In ka badan 1700 oo maqaallo saynis ah ayaa mar hore la daabacay iyadoo lagu salaynayo macluumaadka laga helay telescope-kan orbital.
Si loo gaaro saxsanaanta sare ee khariidadda xiddigta la sameeyay, waxaa aad muhiim u ah in si sax ah loo go'aamiyo booska dayax-gacmeedka marka loo eego Dhulka. Haddaba iyadoo agabka saaran Gaia ay iska baarayaan cirka, ururinta xogta βtiro-koobkaβ ee dadka xiddigaha, xiddigiyayaashu waxay la socdaan booska markabka iyagoo isticmaalaya telescopes indhaha.
Gaar ahaan, ESO VST Survey Telescope (VLT Survey Telescope) oo ku taal goobta kormeerka ee Mount Paranal waxay gacan ka geysataa la socodka booska aaladda. VST hadda waa telescope-ka sahanka indhaha ee ugu weyn aduunka. Waxay diiwaan gelisaa booska Gaia ee xiddigaha habeen kasta sanadka oo dhan.
Indho-indhaynta ay samaysay VST-da waxa adeegsada khubarada ESA ee ku takhasusay dhaq-dhaqaaqa duulimaadka, kuwaas oo la socda oo hagaajiya meeraha Gaia oo si joogto ah u hagaajiya xuduudaheeda. Tani waxay kaa caawinaysaa ururinta khariidadda xiddigaha ugu saxsan taariikhda.
