Scientists have discovered what appear to be twelve smaller black holes orbiting our galaxy’s central giant. Each is thought to actually be a binary system composed of a black hole and a low-mass star. Gas siphoned from the star glows in x-rays as it falls into the black holes, allowing them to be seen.

I guess that means there are many more that can’t be easily seen.
Yep, these 10 or 12 individual black holes must be the biggest and the brightest of the other 10,000 - 20,000. What a hellish place that must be. Better that they all sink to the center than mill around out here with us!
