I don't think that's the right question to be asking. When looking at
distant stars and galaxies and contemplating astrophysics, we should not
pick a default assumption one way or the other as to whether the phenomena
is "natural" or "artificial", since this may corrupt our understanding of
astrophysics and incorporate wrong data, among other reasons. Additionally,
there may be no difference between the two anyway... I suspect that the way
to identify things that we could approximately call life would be to pay
close attention to thermodynamics and the criteria for what counts as life.
See page 215 http://arxiv.org/pdf/1301.1648.pdf but relevant context starts
on page 203. Speaking of which, I am a little confused as to how I have not
already read Freitas' Xenology book ( http://www.xenology.info/Xeno.htm
table of contents).
