RE: STS-73 'beam' observation

My *guess* for the "beam" effect is normal outgassing from the shuttle 
illuminated by the cargo bay lights.  The shuttle is suppose to be 
maintaining a tail down orientation.  It's my understanding that there was 
only one trim burn after the circularization burn shortly after launch and no 
further burns were planned so as to minimize any "g" forces.  My theory is 
since the shuttle hasn't had any accelerations or deaccelerations, any 
outgassing will stay in the immediate area of the shuttle.  
While we are talking about the shuttle, why are they called microgravity 
experients; why not zero gravity experiments?
