    This Sciam article states, 'Both papers provide new, closely related estimates for the mass of the suspected black hole and the distance between our sun and the galactic center, roughly 26,000 light-years away.'

    Is this number generally accepted by professionals now? If I recall, earth is 2/3 out from the galactic center and the milky way is 200,000 ly wide. I don't know, what is the popular sentiment today?

    Your memory is off by a factor of two on the size of the Milky Way: It is about 100,000 light years across.

    That 26,000 light year number is more-or-less consistent with values reported since the early 1990s.
