European Southern Observatory (ESO, European Southern Observatory) yakataura nezve kuitwa kwechirongwa chakakura kugadzira mepu yakakura uye yakarurama kwazvo ine mativi matatu egwara redu renzou munhoroondo.
Mepu yakadzama, inofukidza nyeredzi dzinopfuura bhiriyoni muMilky Way, iri kugadzirwa uchishandisa data kubva kuGaia spacecraft yakatangwa neEuropean Space Agency (ESA) kumashure muna 2013. Zvinopfuura 1700 zvinyorwa zvesainzi zvakatoburitswa zvichibva paruzivo kubva kune ino orbital telescope.
Kuti uwane kurongeka kwepamusoro kwemepu yakagadzirwa nyeredzi, zvakakosha kuti uone chaizvo nzvimbo yechitundumuseremusere maererano nePasi. Saka apo zviridzwa zviri muGaia zvinotarisa denga, zvichitora data ye "census" yehuwandu hwenyeredzi, nyanzvi dzenyeredzi dzinotsvaga nzvimbo yechikepe vachishandisa materesikopu anoona.
Kunyanya, iyo ESO VST Survey Telescope (VLT Survey Telescope) panzvimbo inocherechedzwa paMount Paranal inobatsira kutarisa nzvimbo yechishandiso. VST ndiyo yave teresikopu huru pasi rose yeongororo yemaziso. Inonyora nzvimbo yaGaia pakati penyeredzi humwe husiku humwe hwose gore rose.
Kucherechedzwa kwakaitwa neVST kunoshandiswa nenyanzvi dzeESA dynamics endege, vanotarisisa nekugadzirisa Gaia's orbit uye vachiramba vachinatsa ma paramita ayo. Izvi zvinobatsira mukunyora mepu yenyeredzi yakanyatsojeka munhoroondo.
