Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. Each image covers a 14x14 degree field which includes most of the central bulge of our Milky Way Galaxy . They are probably binary star systems where matter accretes onto a collapsed object, either a neutron star or a black hole . Surprisingly, no high energy source seems to coincide exactly with the Galactic center itself, located near the brightest source at the bottom of both pictures. This indicates that the large black hole thought to be lurking there is unexpectedly quiet at these energies.
