Se\u00a0James Webb -avaruusteleskooppi<\/a>\u00a0(JWST) on Hubblen j\u00e4lkeen seuraava suuri avaruustieteellinen observatorio, ja se on NASA:n, ESA:n ja CSA:n v\u00e4linen loistava yhteisty\u00f6hanke. Se on perustettu vastaamaan kysymyksiin maailmankaikkeudesta ja tekem\u00e4\u00e4n l\u00f6yt\u00f6j\u00e4 kaikilla t\u00e4htitieteen aloilla. JWST tutkii, miten t\u00e4hdet ja planeetat muodostuivat, ja selvitt\u00e4\u00e4 ensimm\u00e4isten galaksien synty\u00e4 varhaisessa maailmankaikkeudessa sek\u00e4 paljon muuta!\u00a0<\/p>\n
