But I just think I found a flaw in the Discovery channel's logic on this one:
There were people IN the thing that blew up, correct? And if there were people, there was air. Since that air is now traveling through space, it should be fuel for an explosion.

So yes, there CAN be explosions in space. I think.
Not all explosions involve combustion; nuclear explosions, for example.

E: And supernovas.
