European Southern Observatory (ESO, European Southern Observatory) inalankhula za kukhazikitsidwa kwa ntchito yaikulu yopangira mapu aakulu kwambiri komanso olondola kwambiri a mlalang'amba wathu m'mbiri.
Mapu atsatanetsatane, omwe ali ndi nyenyezi zoposa biliyoni imodzi mu Milky Way, akupangidwa pogwiritsa ntchito deta yochokera ku Gaia spacecraft yomwe idakhazikitsidwa ndi European Space Agency (ESA) mu 2013. Zolemba zasayansi zopitilira 1700 zasindikizidwa kale kutengera chidziwitso cha telescope yozungulira iyi.
Kuti mukwaniritse kulondola kwakukulu kwa mapu opangidwa ndi nyenyezi, ndikofunikira kwambiri kudziwa bwino malo omwe ndegeyi ili pafupi ndi Dziko Lapansi. Kotero pamene zida zomwe zili mu Gaia zimayang'ana mlengalenga, kusonkhanitsa deta "kalembera" wa nyenyezi za nyenyezi, akatswiri a zakuthambo amafufuza malo a sitimayo pogwiritsa ntchito makina oonera zinthu zakuthambo.
Makamaka, ESO VST Survey Telescope (VLT Survey Telescope) pamalo owonera pa Mount Paranal imathandizira kuwunika momwe chipangizocho chilili. VST tsopano ndi telesikopu yayikulu kwambiri padziko lonse lapansi yowunikira anthu. Imalemba malo a Gaia pakati pa nyenyezi usiku uliwonse chaka chonse.
Zowonera kuchokera ku VST zimagwiritsidwa ntchito ndi akatswiri oyendetsa ndege a ESA omwe amawunika ndikusintha kanjira ka Gaia ndikuwongolera mosalekeza magawo ake. Izi zimathandiza kupanga mapu a nyenyezi olondola kwambiri m'mbiri.
