I-European Southern Observatory (ESO, European Southern Observatory) ikhulume mayelana nokuqaliswa kwephrojekthi enkulu yokwakha imephu enkulu nenembe kakhulu enezinhlangothi ezintathu yomthala wethu emlandweni.
Imephu enemininingwane, ehlanganisa izinkanyezi ezingaphezu kwesigidigidi ku-Milky Way, yenziwa kusetshenziswa idatha evela kumkhumbi-mkhathi we-Gaia owethulwe yi-European Space Agency (ESA) emuva ngo-2013. Izindatshana zesayensi ezingaphezu kwe-1700 sezishicilelwe ngokusekelwe olwazini oluvela kulesi sibonakude se-orbital.
Ukuze kuzuzwe ukunemba okuphezulu kwemephu yenkanyezi ekhiqiziwe, kubaluleke kakhulu ukucacisa ngokunembile indawo yomkhumbi-mkhathi ngokuhlobene noMhlaba. Ngakho-ke ngenkathi amathuluzi agibela i-Gaia ehlola isibhakabhaka, eqoqa idatha "yokubalwa kwabantu" kwezinkanyezi, izazi zezinkanyezi zilandelela indawo yomkhumbi zisebenzisa izibonakude.
Ikakhulukazi, i-ESO VST Survey Telescope (VLT Survey Telescope) endaweni yokubuka i-Mount Paranal isiza ukuqapha ukuma kwedivayisi. I-VST manje isiyisibonakude esikhulu kunazo zonke emhlabeni wokuhlola inhlolovo. Irekhoda isikhundla sikaGaia phakathi kwezinkanyezi njalo ngobusuku obunye unyaka wonke.
Ukuqaphela okwenziwa yi-VST kusetshenziswa ochwepheshe be-ESA flight dynamics, abaqapha futhi balungise umzila we-Gaia futhi baqhubeke becwenga amapharamitha ayo. Lokhu kusiza ekuhlanganiseni imephu yenkanyezi enembe kakhulu emlandweni.
