Are we able to study "weather patterns" within the extremely thin vapours that fill space?

Question

Beyond the reach of any given planet's atmosphere, space has long been known not to be a vacuum, just very, very thin air. Regardless of how thin it is, there must be a countless array of "atmospheric" activity. What kinds of "weather systems" might one expect to observe in outer space? Could there be any phenomenon similar to "lightening" or "rain"?

Answer 1

There are definitely types of lightning in various parts of our universe, however lightning is an electron stream that needs: + & -  (plus & negative) attributes (pole & antipole) for it to move in the event moment.

But space is known as absolute zero, and there are very interesting things that happen to atoms in the absolute zero atmosphere. Water has to be in a certain temp zone to be fluid so rain is not possible in space.

FYI: I think PBS has a video called: The Race to Absolute Zero, you may find it very interesting, I did.
