Rare ‘Missing Link’ Black Hole Apparently Found

A newfound cosmic object may be a long-sought missing link that could help flesh out the black hole family tree.

The object appears to be an intermediate-mass black hole (IMBH), astronomers say. Called NGC-2276-3c, it lies in an arm of the spiral galaxy NGC-2276, about 100 million light-years from Earth.

Is this the same as the one reported six months ago? I’ll check. http://www.space.com/26857-medium-size-black-hole-discovery-m82.html

No, this is different. The new one in NGC-2276 weighs 50,000 suns. The one in M82 “weighs in at 428 solar masses, give or take a hundred suns or so”. That’s a big size variation to be counted in the same category, but intermediate-mass black holes are defined as those that “harbor between 100 and several hundred thousand solar masses.”

Because of these two, the wikipedia article https://en.wikipedia.org/wiki/Intermediate-mass_black_hole
is now out of date.

The only thing that is constant is change. ( not sure who said this)
