since space does not contain air, is it possible to create a soap bubble without air in space or in vacuum and can can you explain why so? OR will there be any possibilities for a bubble in such kind of environment? OR will a bubble exist without air in vacuum or space?

As all soap bubbles have a fleeting existence, one created in space would have an even more fleeting existence. Since space contains no air how a bubble could be formed would be different than in an atmosphere. Pragmatically it seems that one would first create a ball of liquid then blow an air bubble into it via something like a straw. Another method might be having a ball of liquid and then injecting a solid pellet of some chemical that would sublime into a gas, like solid CO2.
I'll point out that your question just says "in space" which doesn't eliminate the possibility of creating soap bubbles inside a space ship with air. This however seems to be out of scope.

Yes, you could form a bubble in space. A bubble exists when there is equilibrium between the surface tension of the enveloping material and the positive pressure differential between the gas inside and that outside. There's no need for the gas outside to have any particular pressure.
