 Mbido ndụ na agụmakwụkwọ 
A mụrụ Okoye na Amawbia, na ndịda ọwụwa anyanwụ Naịjirịa. Ọ bụ nwa Simeon na Agnes Okoye, ọ bụkwa nwa nke ise n'ime ụmụ itoolu.

Okoye mere nke ọma n'agụmakwụkwọ, wee nweta ohere agụmakwụkwọ iji gaa ụlọ akwụkwọ sekọndrị gọọmentị dị na Owerri. E mechara kweta na ọ gụrụ Fiziks na Mahadum Ibadan, nke nwere njikọ na Mahadum London mgbe ahụ.

Na 1962, ọ gụsịrị akwụkwọ na ọkwa First Class ma nye ya ihe nrite ngalaba maka nwa akwụkwọ kacha mma gụsịrị akwụkwọ. O mechara nweta onyinye Carnegie Foundation Fellowship dị elu—ihe nrite a ma ama n'ụwa niile—nke mere ka o nwee ike ịchụso Doctor of Philosophy (PhD) na Mahadum Cambridge, United Kingdom. 

Mgbe Okoye sonyeere, otu nnyocha ahụ amụbaala wee bụrụ Mullard Radio Astronomy Observatory. N'okpuru nlekọta nke Antony Hewish, o mere nyocha banyere nhazi nke interplanetary medium site na usoro scintillation. O chepụtara ma wuo antenna reflector nkuku abụọ yana sekit ha na-agbanwe ìhè. Ngwa a mere ka ọ nwee ike ịmụ banyere ikuku redio sitere na Crab Nebula. ”

Okoye keere òkè dị mkpa na nyocha nke nyere aka na Antony Hewish ịnata 1974 Nobel Prize na Physics. N'okwu nnabata Nobel ya, Hewish kwetara na Okoye jikọrọ aka na nchọpụta nke kpakpando neutron. O kwuru, sị: "Isi iyi mbụ a na-adịghị ahụkebe nke a ga-achọpụta site na usoro a pụtara na 1965 mgbe, mụ na nwa akwụkwọ m Okoye, m na-amụ redio sitere na Crab Nebula. Anyị chọtara ihe a ma ama na-egbuke egbuke n'ime nebula nke dị obere nke ukwuu iji kọwaa ya site na radiation synchrotron, anyị tụkwara aro na nke a nwere ike ịbụ ihe fọdụrụ na kpakpando mbụ nke gbawara ma gosipụta ọrụ n'ụdị mgbapụta redio a ka ọ dịghị ihe ọzọ karịa Crab. 

N'oge ọ nọ na Cambridge, o guzobere njikọ agụmakwụkwọ ma na United Kingdom ma na mba ụwa. Ọrụ nyocha ya gụnyere nleta na Leiden Observatory na Netherlands na National Radio Astronomy Observatory na Charlottesville, Virginia, USA.

 Ọrụ 
Okoye laghachiri Naịjirịa n'afọ 1965 mgbe ọ gụchara akwụkwọ doctorate ya wee malite ikwu okwu na fiziki na Mahadum Ibadan. Na 1967, obere oge tupu Agha Obodo Naịjirịa, ọ banyere na Mahadum Naịjirịa, Nsukka. Na 1972, o hiwere Ụlọ Nnyocha Eluigwe na Mahadum ahụ ma họpụta ya Prọfesọ nke Fiziki na 1976. 

Okoye laghachiri na Cambridge na 1971 dịka onye otu Commonwealth Academic Staff Fellow na Mahadum Cambridge. Ọ bụ onye ọbịa na Institute of Astronomy (IoA) na onye otu Churchill College. Na IoA, n'okpuru nlekọta nke Fred Hoyle, o mere ka ihe ọmụma ya banyere plasma physics, relativity izugbe, na cosmology dị ọhụrụ, ma na-eguzobekwa nyocha nke ya na astrophysics ike dị elu. N'oge a, o bipụtara na data X-ray sitere na galaxies redio na jet nke M87.
