Ua ʻōlelo ka European Southern Observatory (ESO, European Southern Observatory) e pili ana i ka hoʻokō ʻana i kahi papahana nui e hana i ka palapala ʻāina ʻekolu-dimensional nui a pololei loa o kā mākou galaxy i ka mōʻaukala.
ʻO ka palapala ʻāina kikoʻī, e uhi ana ma mua o hoʻokahi piliona mau hōkū ma Milky Way, ke hana ʻia nei me ka hoʻohana ʻana i ka ʻikepili mai ka mokulele Gaia i hoʻokumu ʻia e ka European Space Agency (ESA) i ka makahiki 2013. ʻOi aku ma mua o 1700 mau ʻatikala ʻepekema i paʻi ʻia ma muli o ka ʻike mai kēia telescope orbital.
No ka loaʻa ʻana o ka pololei kiʻekiʻe o ka palapala ʻāina hōkū i hana ʻia, he mea nui e hoʻoholo pololei i ke kūlana o ka mokulele e pili ana i ka Honua. No laila, ʻoiai nā mea hana ma luna o Gaia e nānā i ka lewa, e hōʻiliʻili ana i ka ʻikepili no ka "helu helu" o ka heluna hōkū, ʻike nā astronomers i ke kūlana o ka moku me ka hoʻohana ʻana i nā telescope optical.
ʻO ka mea kūikawā, ʻo ka ESO VST Survey Telescope (VLT Survey Telescope) ma ka mākaʻikaʻi ma ka mauna Paranal e kōkua i ka nānā ʻana i ke kūlana o ka hāmeʻa. ʻO ka VST ka telescope noiʻi optical nui loa o ka honua i kēia manawa. Hoʻopaʻa ia i ke kūlana o Gaia ma waena o nā hōkū i kēlā me kēia pō ʻē aʻe o ka makahiki.
Hoʻohana ʻia nā ʻike i hana ʻia e ka VST e nā loea hoʻokele mokulele ESA, nāna e nānā a hoʻoponopono i ka orbit o Gaia a hoʻomaʻamaʻa mau i kāna mau palena. Kōkua kēia i ka hōʻuluʻulu ʻana i ka palapala ʻāina hōkū pololei loa ma ka mōʻaukala.
