Poyasnenie: Zvezdy, pohozhie na Solnce, ispol'zuyut v kachestve topliva vodorod, kotoryi v ih yadrah prevrashaetsya v gelii, "sgoraya" v termoyadernyh reakciyah, No chto proishodit, kogda vodorod zakanchivaetsya? V techenie nekotorogo vremeni vodorod gorit v okruzhayushei yadro obolochke, v rezul'tate chego zvezda rasshiryaetsya i stanovitsya krasnym gigantom. Na etom krasivom dvuhcvetnom izobrazhenii, poluchennom iz dvuh snimkov sharovogo zvezdnogo skopleniya M10, yarkie krasno-oranzhevye zvezdy kak raz i yavlyayut soboi primer opisannoi vyshe fazy zvezdnoi evolyucii. Yarkie golubye zvezdy, vidimye v M10, poshli dal'she prostogo goreniya vodoroda v obolochke. Eti zvezdy obrazuyut "gorizontal'nuyu vetvv'" gigantov s temperaturoi yadra dostatochnoi dlya prevrasheniya v nem geliya v uglerod. Na etom izobrazhenii tol'ko edva zametnye, slabye, serovatye zvezdy, veroyatno, eshe szhigayut vodorod v svoih yadrah.
