There are many different gases in space.
Just to get the gas together, gravity is so big that it needs to be pulled.
That's how big a planet is.

There is a lot of air on Earth, but there is no air on the moon because
In the case of the moon, the mass is small, so the manpower is small, so it is not enough to hold the air.

If you look at the empty space itself, there's no mass, so there's no air.
A planet that has a large mass and is large enough to attract will take the gas.
Or there are times when they're just huge in the form of nebulae.

Isn't there a tiny amount of oxygen and nitrogen like Earth in the universe?
It's so wide that it's only low in density.

The universe itself is rich in plasma.
Continuous heating of gaseous materials produces a collection of particles of ionic nuclei and free electrons, which is plasma.
So there's already plenty of plasma in the universe that can be a gas.
