Kwete, vazhinji venyeredzi vaizivawo kuti nzira yeMilky yakakotama, ingangoita mifananidzo yese, ichi chokwadi chakadzikiswa kuti chidimbu kana kusavapo kwedata chaiyo. Nekudaro, masayendisiti eAmerica kubva kuYunivhesiti yemhandara akasika kuona idzva kuratidza mamiriro chaiwo echokwadi. Sekureva kweiyo portal, iri basa chikamu chechikamu chikuru-chiyero "Slicianovsky Digital Dat Comment" (SDSS). Iko kuvonekwa kwakatanga kuratidzwa mumusangano wechi257 weAmerican Saltronomical Society (AAS).
Kuvapo kwekukotama mundege yemapuranga emvura yakawanikwa kwenguva yakareba - panguva imwe chete neyekutanga kutsanangurwa kwezvinhu zvakadaro. Izvo chaizvo zvinokonzeresa mafungu akadaro hazviverengeke. Iyo inonzwisisika inotaridzika yemhando mazvinoita kuti ive yekukonzera mhedzisiro yeimwe girazi, yaive pedyo neyakaipfuura pfupi. Kudyidzana kwakadaro kunopfuura, mapoka enyeredzi anobviswa kubva kune mumwe nemumwe kana kuve satellite, uye nyeredzi mukati mavo vari kufamba pane iyo yakashandurwa trajectories kwenguva yakareba. Iyo Milky Way yakasangana neyakadaro mutambi wekudzikama anenge mabhiriyoni matatu emakore apfuura - munguva pfupi yapfuura pane cosmological zviyero.
Kuti uone zvakakomba zvakadaro muGirazi rake, masayendisiti aifanira kushanda akanaka. Seti mbiri dze data dzakashandiswa kamwechete: kubva kuApogee Everiment Apochi-point Observatory muNew Mexico (USA) uye mhedzisiro yeEuropean Orbital Telescope Gaia. Iko kushamisika kwekuona kwekutora girazi hakusi kungova vhidhiyo yakanaka. Ichi chigadzirwa chakananga chezvikamu zvitatu zvemakwenzi weClototophy yeiyo Milky Way, iyo yakasarudzika basa kuti uone chinzvimbo chaicho mumazana ezviuru zveyeredzi nyeredzi.
Sechikamu cheApogee, teresikopu ine girazi 2.5-metrema kwemakore anenge gumi akadzidza kuita kwezviuru zvemazana emazana emakondo. Izvi zvaitenderwa kwete kungoziva zvavanyori, asi zvakare kuti tisimbise zera renyeredzi, pamwe nezvimwe zvinhu zvekufamba. Ipapo data iri rakabatanidzwa neruzivo rwunowanikwa neGaia Zvishandiso. Kutenda kwaari, zvakare, vazivi venyeredzi vanoziva iyo chaiyo kure kubva pasi kusvika kumamiriyoni enyeredzi nyeredzi. Nekuda kwekuenzanisa, zvaigoneka kuumba mepu yenzvimbo yeiyo Luminaire uye ona kuti vanozeza sei, sekunge pane hofori hofori.
