Hi Ben,

  The shape of a bubble results from the very strong surface tension of 
the liquid from which the bubble is made.  This surface tension is much 
stronger than gravity.  Therefore, the shape of a bubble in space would be 
the same as that here on the ground, a sphere.  The sphere might be a 
little bit rounder and it might last a little bit longer than it would on 
the Earth.  You can find the answer from others and more information about 
this question at 
Bubbles in Space
