Vi bor i en av armarna i en stor spiralgalax som kallas Vintergatan. Solen och dess planeter (inklusive jorden) ligger i denna lugna del av galaxen, ungef\u00e4r halvv\u00e4gs ut fr\u00e5n centrum.<\/p>\n<\/div>\n

Vintergatan har formen av en enorm virvel som roterar ett varv vart 200 miljoner \u00e5r. Den best\u00e5r av minst 100 miljarder stj\u00e4rnor, samt stoft och gas. Den \u00e4r s\u00e5 stor att ljuset tar
Det tar 100 000 \u00e5r att ta sig fr\u00e5n den ena sidan till den andra.<\/p>\n

Det \u00e4r mycket sv\u00e5rt att se galaxens centrum eftersom gas- och stoftmoln skymmer utsikten. Forskarna tror att det finns ett supermassivt svart h\u00e5l d\u00e4r som slukar allt som kommer f\u00f6r n\u00e4ra.<\/p>\n

Utanf\u00f6r huvudspiralen finns cirka 200 klotformiga stj\u00e4rnhopar. Varje \u2018klotformig stj\u00e4rnhop\u2019 \u00e4r mycket gammal och inneh\u00e5ller upp till en miljon stj\u00e4rnor. Vintergatan ing\u00e5r i en grupp best\u00e5ende av minst 40 galaxer. Den s\u00e5 kallade Lokala gruppen best\u00e5r av tv\u00e5 stora spiralgalaxer \u2013 Vintergatan och Andromeda.<\/p>\n

De \u00f6vriga \u00e4r betydligt mindre. Bland dem finns tv\u00e5 galaxer som kan ses med blotta \u00f6gat fr\u00e5n l\u00e4nder s\u00f6der om ekvatorn. Galaxerna kallas Magellanska molnen, uppkallade efter den portugisiske uppt\u00e4cktsresanden Ferdinand Magellan.<\/p>","protected":false},"excerpt":{"rendered":"
