      No, there is no air in space because it is a vacuum.

      Space is a vacuum so you can’t even hear people scream. 100 km above the earth the atmosphere stops and there is no air.

      Kind of. Air (atmospheres) are around planets like Earth and Mars because of the gravity the mass of the planet creates. Earths atmosphere is slowly bleeding off into space, but replenished by plants and volcanoes.

      Outside of an atmosphere, there is only a cold (-273 deg C) hard vacuum.

      And no plants.
