Just out into deeper and deeper space.
Space is vacuum – there’s nothing out there, so the air molecules just keep going.
Imagine setting up a pool table (aka a billiards table) and breaking the big pile of balls in the middle. Inside of the space-station the balls bounce around and we can breathe them. In space, there are no bumpers – the balls just keep going forever, or at least until they run into another planet/star/moon/etc.
Out in deep space, there’s very, very little matter – estimates vary, but something like 1 molecule per cubit meter of volume is a ballpark figure.
