The are no practical examples of gases forming clouds in a vacuum, in practice a pressurized system cannot exist in a vacuum without a physical barrier to prevent equilibrium of the gases from occurring. This is why we store gases inside a can or bottle, if these containers are punctured the pressurized gases equilibriate into the outer atmosphere.
This image is a composite including infrared and false colours like all the space art we are given.
The only place space exists is in our imagination:
Have a look at the "Planets" through a telescope and you can understand why they are called wandering stars, bright lights which always show their face towards us just like the moon.
Only two of the wandering stars actually wax and wane whist the others are always fully lit, One even twinkles and flashes colour like the stars. They also rotate clockwise keeping the same face towards the earth as they travel east to west and are mirrored if viewed north of the equator compared to south of the equator just like the sun and moon.
