Tr\u0103im \u00eentr-unul dintre bra\u021bele unei mari galaxii spirale numit\u0103 Calea Lactee. Soarele \u0219i planetele sale (inclusiv P\u0103m\u00e2ntul) se afl\u0103 \u00een aceast\u0103 parte lini\u0219tit\u0103 a galaxiei, la aproximativ jum\u0103tatea distan\u021bei fa\u021b\u0103 de centru.<\/p>\n<\/div>\n

Calea Lactee are forma unui v\u00e2rtej uria\u0219 care se rote\u0219te o dat\u0103 la 200 de milioane de ani. Este alc\u0103tuit\u0103 din cel pu\u021bin 100 de miliarde de stele, precum \u0219i din praf \u0219i gaz. Este at\u00e2t de mare \u00eenc\u00e2t lumina are nevoie de
100 000 de ani pentru a traversa de pe o parte pe cealalt\u0103.<\/p>\n

Centrul Galaxiei este foarte greu de observat, deoarece norii de gaz \u0219i praf ne blocheaz\u0103 vederea. Oamenii de \u0219tiin\u021b\u0103 consider\u0103 c\u0103 acesta con\u021bine o gaur\u0103 neagr\u0103 supermasiv\u0103 care \u00eenghite orice obiect care se apropie prea mult.<\/p>\n

\u00cen afara spiralei principale se afl\u0103 aproximativ 200 de roiuri stelare sferice. Fiecare \u2018roi globular\u2019 este foarte vechi \u0219i con\u021bine p\u00e2n\u0103 la un milion de stele. Calea Lactee face parte dintr-un grup de cel pu\u021bin 40 de galaxii. A\u0219a-numitul Grup Local cuprinde dou\u0103 galaxii spirale mari \u2013 Calea Lactee \u0219i Andromeda.<\/p>\n

Celelalte sunt mult mai mici. Printre acestea se num\u0103r\u0103 dou\u0103 galaxii care pot fi observate cu ochiul liber din \u021b\u0103rile situate la sud de ecuator. Galaxiile se numesc Norii Magellanici, dup\u0103 exploratorul portughez Ferdinand Magellan.<\/p>","protected":false},"excerpt":{"rendered":"
