How interplanetory rockets move? Since they travel in vacuum, from where they get reaction (thrust)?

me_iitd asked:
When rocket travels through space with no medium, from which object it gets thrust. Jet airplanes get the thrust from air. They push air backwards and air push them forward. Newtons third law of motion.
Thanks signal_e. But firstly I am not talking about air as oxygen perspective. There has to be oxygen on board to support combustion. Now back to question, when jet airplanes expel their combustion high pressure gases outside. The air there opposes to them to come out, since combustion gases displaces air. But in space there is no air (or anythig else) to resist. The HP gases may just get ****** in the vacuum putting the rocket on stall. When rockets are invented one great engineer said (I forgot his name), “rockets will not work in space, since there is no medium to push them.” But he was wrong when rockets really travelled in space.
