Te emisije nastajajo visoko nad vsakim planetom zaradi istih son\u010dnih delcev, ki povzro\u010dajo, da severni sij osvetljuje nebo pod njim. Do zdaj so astronomi domnevali, da se ti radijski valovi \u0161irijo v vesolje v obliki vedno \u0161ir\u0161ega sto\u017eca, podobno kot svetloba iz svetilke. Zahvaljujo\u010d misiji Cluster zdaj vemo, da to ni res.<\/p>\n<p>Ko so valovi radijskih valov zaporedoma preplavili vsako vesoljsko plovilo, so znanstveniki lahko izra\u010dunali njihovo velikost in lokacijo. Izka\u017ee se, da se signali po vesolju \u0161irijo v ozkem \u017earku. Zaradi tega je veliko la\u017eje natan\u010dno ugotoviti, od kod prihajajo.
