   How _exactly_ should we be looking for life that we don't recognize or   
   understand?  Water-dependent carbon-based life as we currently   
   understand it has certain effects on the planet.  Certain specific   
   changes in the atmosphere being a big one.   
      
   So please enlighten us, what atmospheric chemical traces do we need to   
   be looking for on exo-planets for silicon based life?  How about   
   hydrogen based life in Jovian planets?  How do we detect that?  What   
   about life based on a very short half-life transuranic radioactive   
   element that doesn't exist on Earth anymore?
