Na Sepa 1959, ndị na-kaka nhọrọ Giuseppe Cocconi na Philip Morrison .

Ha Ibu aro ka ndị ike ibusa ozi ndị dị otú ahụ n'ogologo nke 21 sentimita (1,420.4 MHz ). Nke a bụ ogologo ebili mmiri nke ikuku ikuku site na hydrogen na-anọpụ iche, ihe izi na mbara igwe, ha chere na isi ndị ọzọ nwere ike ịhụ nke a dị ka akara ezi uche dị na redio spectrum .
