Poyasnenie: Chto yavilos' prichinoi vozniknoveniya etoi neobychnoi struktury vblizi centra Galaktiki? Dlinnye parallel'nye luchi v verhnei chasti etogo radioizobrazheniya, vystupayushie iz galakticheskoi ploskosti, izvestny kak radio-duga v centre Galaktiki. Eta radio-duga svyazana s centrom Galaktiki strannymi izognutymi voloknami, pohozhimi na arki. Yarkii radioistochnik vnizu sprava, vozmozhno, okruzhaet chernuyu dyru, nahodyashuyusya v centre Galaktiki. On nazyvaetsya Strelec A* (Srg A*). Odna iz gipotez ob'yasnyaet proishozhdenie radio-dugi i svyazannyh s nei arok tem, chto oni soderzhat goryachuyu plazmu, tekushuyu vdol' linii postoyannogo magnitnogo polya. Etim i ob'yasnyaetsya geometriya "arochnoi struktury". Izobrazheniya, poluchennye na rentgenovskoi observatorii Chandra, svidetel'stvuyut o stolknovenii plazmy s nahodyashimsya nepodaleku oblakom holodnogo gaza.
