Misiunea Gaia a ESA a fost lansat\u0103 \u00een aceast\u0103 diminea\u021b\u0103 cu o rachet\u0103 Soyuz de la Centrul Spa\u021bial European din Kourou, Guyana Francez\u0103, pornind \u00eentr-o misiune fascinant\u0103 de studiere a unui miliard de sori.<\/p>\n<\/div>\n

Gaia va realiza cea mai precis\u0103 hart\u0103 a C\u0103ii Lactee realizat\u0103 p\u00e2n\u0103 \u00een prezent. Prin efectuarea unor m\u0103sur\u0103tori precise ale pozi\u021biilor \u0219i mi\u0219c\u0103rilor unui miliard de stele, misiunea va oferi r\u0103spunsuri la \u00eentreb\u0103ri privind originea \u0219i evolu\u021bia Galaxiei noastre.<\/p>\n

Gaia se \u00eendreapt\u0103 acum c\u0103tre o orbit\u0103 \u00een jurul unui punct virtual din spa\u021biu numit L2, situat la aproximativ 1,5 milioane de kilometri dincolo de P\u0103m\u00e2nt, privit din perspectiva Soarelui.<\/p>\n

Scan\u00e2nd \u00een mod repetat cerul, Gaia va observa fiecare dintre cele un miliard de stele, \u00een medie, de c\u00e2te 70 de ori pe fiecare, pe parcursul celor cinci ani. Va m\u0103sura pozi\u021bia \u0219i propriet\u0103\u021bile fizice esen\u021biale ale fiec\u0103rei stele, inclusiv luminozitatea, temperatura \u0219i compozi\u021bia chimic\u0103 a acesteia.<\/p>\n

Mi\u0219c\u0103rile stelelor pot fi \u2018derulate \u00eenapoi\u2019 pentru a afla mai multe despre originea lor \u0219i despre modul \u00een care Calea Lactee s-a format de-a lungul a miliarde de ani prin fuziunea unor galaxii mai mici, \u0219i pot fi \u2018derulate \u00eenainte\u2019 pentru a afla mai multe despre soarta sa final\u0103.<\/p>\n

Prin compararea scan\u0103rilor repetate ale cerului, Gaia va descoperi, de asemenea, zeci de mii de supernove, strig\u0103tele de moarte ale stelelor care, ajung\u00e2nd la sf\u00e2r\u0219itul vie\u021bii, explodeaz\u0103. Iar u\u0219oarele oscila\u021bii periodice ale pozi\u021biilor unor stele ar trebui s\u0103 dezv\u0103luie prezen\u021ba planetelor care orbiteaz\u0103 \u00een jurul lor, deoarece acestea atrag stelele dintr-o parte \u00een alta.<\/p>\n

De asemenea, Gaia va descoperi noi asteroizi \u00een Sistemul nostru Solar \u0219i va rafina orbitele celor deja cunoscu\u021bi, precum \u0219i va efectua teste precise ale celebrei teorii a relativit\u0103\u021bii generale a lui Einstein.<\/p>","protected":false},"excerpt":{"rendered":"
