No, there is neither air nor breathable oxygen in the vast expanse of space. Space is essentially a vacuum, completely devoid of matter, including the air molecules we rely on for breathing.
Why is there no air in space?
The absence of air in space is primarily due to the vacuum of space. A vacuum is a space entirely devoid of matter. This means there are no gas molecules, including oxygen, nitrogen, or other components of air, present to form an atmosphere.
On Earth, gravity holds our atmosphere in place, preventing gases like oxygen from escaping into space. Space lacks this significant gravitational pull to retain gases and create an atmosphere.

Oxygen in Space: A Different Perspective
While there's no breathable air, oxygen does exist in space, but not in a form we can use. It is found as a component of molecules in different celestial bodies or as trace amounts dispersed thinly within certain regions. Why there is so little breathable oxygen in space | Science | AAAS For example, molecular oxygen has been detected in the extremely thin atmosphere of Jupiter's moon Europa. Hubble Finds Oxygen Atmosphere on Jupiter's Moon Europa ... However, this oxygen is not present in sufficient concentrations or in a breathable form for humans. The absence of a significant amount of free, molecular oxygen capable of sustaining life is what makes space uninhabitable for humans without protective gear.
The Significance of the Vacuum
It's crucial to understand that the absence of oxygen in space is not the sole reason why there's no air. The lack of any significant amount of matter, or the vacuum, is the defining characteristic of space. Is there absolutely no air in space, or just no oxygen? - Quora This vacuum also means the absence of sound propagation as sound needs a medium (like air or water) to travel through.
