This one is the most distant yet, 3 billion light years, it was detected on January 4 2017, 2 Black Holes of 36 and 29 solar masses collided and resulted in a Black Hole of 49 solar masses with the missing mass going into Gravity Wave energy:

These two masses were 19 and 31.  John you scared me a bit with the 36/29, these being the masses of the first detected pair.  If we had two pairs of the same masses, I would think we have some kind of problem with the instrument.  No worries, we had about 2 solar masses go into gravitational energy.

 

Fun aside, the older ones among us may recall our misspent childhood when we first read about black holes.  Note how little was known about them back in the bad old days, oy vey.  Now we are seeing these mergers more often than Jingle Bells.  Cool!
