I'm sure the aliens reading that are saying "Thank god! They aren't coming here." :-)
But on a more serious note, this is some great science. I am super impressed by how sensitive the instruments need to be to chart the fluctuations due to mass here at 20 light years. I'm always on the fence about whether or not we should focus a beam of RF with some modulation on it in their direction, on the one hand it would say "hello! we see you!" on the other that might not be a good idea.
