Westerlund 2 se rozprost\u00edr\u00e1 mezi 6 a 13 sv\u011bteln\u00fdmi roky a obsahuje n\u011bkter\u00e9 z nej\u017ehav\u011bj\u0161\u00edch a nejhmotn\u011bj\u0161\u00edch hv\u011bzd v galaxii.

Nejde jen o estetiku; Data JWST tak\u00e9 zahrnuj\u00ed populaci hn\u011bd\u00fdch trpasl\u00edk\u016f v mlhovin\u011b \u2013 objekt\u016f, kter\u00e9 jsou jen desetkr\u00e1t v\u011bt\u0161\u00ed ne\u017e Jupiter.

Schopnost JWST proniknout hust\u00fdmi oblaky plynu a odhalit skryt\u00e9 hv\u011bzdy znamen\u00e1 v\u00fdznamn\u00fd pokrok v astronomick\u00fdch pozorov\u00e1n\u00edch.
