Two oxygen atoms in a oxygen molecule share two electrons.  Oxygen atoms only have 6 valence electrons (electrons in the outer shell).  They want 8 electrons so they need to steal two or share two. 

It is easier for two oxygen molecules to share their electrons then to find two atoms to steal one from or find one atom to steal two from.  The two oxygen atoms share two electrons so that they each have 8 electrons in their outer shell and are therefore full.

They are bonded together with a covalent bond.  A covalent bond is a strong bond when two atoms are sharing outer electrons.
