Az ESA Gaia-misszi\u00f3ja ma reggel egy Szojuz rak\u00e9t\u00e1val indult \u00fatj\u00e1ra az eur\u00f3pai \u0171rkik\u00f6t\u0151b\u0151l, a francia-guyanai Kourou-b\u00f3l, hogy izgalmas k\u00fcldet\u00e9s\u00e9re induljon: egymilli\u00e1rd nap tanulm\u00e1nyoz\u00e1s\u00e1ra.<\/p>\n<\/div>\n

A Gaia elk\u00e9sz\u00edti a Tej\u00fat eddigi legpontosabb t\u00e9rk\u00e9p\u00e9t. Egymilli\u00e1rd csillag helyzet\u00e9nek \u00e9s mozg\u00e1s\u00e1nak pontos m\u00e9r\u00e9s\u00e9vel v\u00e1laszt ad majd galaxisunk eredet\u00e9vel \u00e9s fejl\u0151d\u00e9s\u00e9vel kapcsolatos k\u00e9rd\u00e9sekre.<\/p>\n

A Gaia jelenleg az L2 nev\u0171 virtu\u00e1lis pont k\u00f6r\u00fcli p\u00e1ly\u00e1ra tart, amely a Napb\u00f3l n\u00e9zve k\u00f6r\u00fclbel\u00fcl 1,5 milli\u00f3 kilom\u00e9terre fekszik a F\u00f6ldt\u0151l.<\/p>\n

A Gaia az eget folyamatosan p\u00e1szt\u00e1zva az \u00f6t \u00e9v alatt az egymilli\u00e1rd csillag mindegyik\u00e9t \u00e1tlagosan 70-szer fogja megfigyelni. Meg fogja m\u00e9rni minden csillag helyzet\u00e9t \u00e9s legfontosabb fizikai tulajdons\u00e1gait, bele\u00e9rtve a f\u00e9nyess\u00e9g\u00e9t, h\u0151m\u00e9rs\u00e9klet\u00e9t \u00e9s k\u00e9miai \u00f6sszet\u00e9tel\u00e9t.<\/p>\n

A Gaia emellett \u00faj aszteroid\u00e1kat fog felfedezni a Naprendszer\u00fcnkben, pontos\u00edtani fogja a m\u00e1r ismert aszteroid\u00e1k p\u00e1ly\u00e1it, valamint pontos vizsg\u00e1latokat fog v\u00e9gezni Einstein h\u00edres \u00e1ltal\u00e1nos relativit\u00e1selm\u00e9let\u00e9nek ellen\u0151rz\u00e9s\u00e9re.<\/p>","protected":false},"excerpt":{"rendered":"
