If there is no oxygen in space, how are there explotions with fire?
Answer 1:

I assume that you mean the space shuttle explosions, which occurred when the spacecrafts re-entered the atmosphere. There is some research concerning 'flame balls,' small, invisible balls of fire that give off as much thermal power as 1/50th of a candle. In these experiments, oxygen is supplied via diffusion (ask your teacher if you haven't heard that word),but is in trace amounts on board the spacecraft.
