We demonstrate that in X-ray observations there is objective (almost model independent) information regarding the nature compact objects [neutron stars (NS) and black holes (BH)]. We illuminate status of our results obtained so far from Galactic and extragalactic black hole candidates neutron star and impacts.We provide almost independent observational signatures of BH and NS sources.
