Hey Space Placers!
The SECOND observation of Gravitational Waves has been announced by the LIGO team - see my previous posts for background.
This discovery was due to the merger of two black holes that were 1.4 billion light years from Earth. These black holes were far smaller than the black holes involved in the first GW detection. This discovery is very important in that it shows that the first observation was not a "one and done" event, that these mergers are ongoing.
You can read more about it here and here.
I can hardly wait to see where GW Astronomy takes us....it is going to be interesting, that's for sure.
