ESA Gaia-missioon startis t\u00e4na hommikul Sojuz-raketiga Euroopa kosmosesadamast Kourous Prantsuse Guajaanas, et alustada oma p\u00f5nevat missiooni miljardi t\u00e4he uurimiseks.<\/p>\n<\/div>\n

Gaia koostab Linnutee seni k\u00f5ige t\u00e4psema kaardi. M\u00f5\u00f5tes t\u00e4pselt miljardi t\u00e4he asukohta ja liikumist, annab see vastuseid meie galaktika tekke ja arengu kohta.<\/p>\n

Gaia on n\u00fc\u00fcd teel orbiidile, mis asub kosmoses virtuaalse punkti \u00fcmber, mida nimetatakse L2-ks ja mis asub P\u00e4ikesest vaadatuna Maast umbes 1,5 miljoni kilomeetri kaugusel.<\/p>\n

Gaia vaatleb taevast korduvalt ning j\u00e4lgib viie aasta jooksul iga\u00fcht miljardist t\u00e4hest keskmiselt 70 korda. Ta m\u00f5\u00f5dab iga t\u00e4he asukohta ja peamisi f\u00fc\u00fcsikalisi omadusi, sealhulgas selle heledust, temperatuuri ja keemilist koostist.<\/p>\n

T\u00e4htede liikumist saab \u2018tagasi kerida\u2019, et saada rohkem teavet nende p\u00e4ritolu kohta ja selle kohta, kuidas Linnutee on miljardite aastate jooksul tekkinud v\u00e4iksemate galaktikate \u00fchinemise tulemusel, ning \u2018edasi kerida\u2019, et saada rohkem teavet selle l\u00f5pliku saatuse kohta.<\/p>\n

V\u00f5rreldes oma korduvaid taevaskannimisi avastab Gaia ka k\u00fcmneid tuhandeid supernoovasid \u2013 t\u00e4htede surmakarjeid, kui need j\u00f5uavad oma elu l\u00f5pule ja plahvatavad. Samuti peaksid m\u00f5nede t\u00e4htede asukoha kerged perioodilised k\u00f5ikumised paljastama nende \u00fcmber tiirlevate planeetide olemasolu, kuna need t\u00f5mbavad t\u00e4hti \u00fchelt poolt teisele.<\/p>\n

Gaia avastab ka uusi asteroide meie P\u00e4ikeses\u00fcsteemis, t\u00e4psustab juba teadaolevate asteroide orbiite ning viib l\u00e4bi Einsteini kuulsat \u00fcldrelatiivsusteooriat k\u00e4sitlevad t\u00e4psed katsed.<\/p>","protected":false},"excerpt":{"rendered":"
