This oxygen is not floating freely in space but is held within the geological structures of these distant worlds, demonstrating that the building blocks for potential extraterrestrial life may exist in our neighborhood. In the vast expanse between galaxies, the density of matter is incredibly low, but it is not zero.
Harnessing Space Oxygen Resource Potential for Future Exploration
While the Martian atmosphere is 95% carbon dioxide, trace amounts of oxygen gas have been detected by robotic missions. This oxygen is not floating freely in space but is held within the geological structures of these distant worlds, demonstrating that the building blocks for potential extraterrestrial life may exist in our neighborhood.
During the stellar lifecycle, massive stars fuse lighter elements into oxygen, which is eventually scattered into space upon the star's death. These regions contain a sparse soup of atoms and molecules, far less dense than the air we breathe, but still physically present.

Physics defines a perfect vacuum as a space containing no matter, essentially zero particles. Yet, to declare space a perfect vacuum is an oversimplification.
