guys and gals.. we might've seen lot of space science films in which we've seen lot of explosions and fire effects... i couldn't find a reasonable answer for the follwin question in the net.. so if u have..let's discuss

burnin process definitely need oxygen.. but i think ther's no O2 out of our atmos.. and ther's no air probably to support combustion process... then how do we get large explosions in outer space..?????
and the physics out ther is completely different compared to tat we have in earth... if u find any reasonable explanations.. let me kno soon... thanks in advance
