      Hi #love turquoise,

      In outer space, the pressure is too low (vacuum) for water to remain or become liquid, so rain will not be possible. However, there may be Earth-like planets in the universe that have water or other liquids that can evaporate into the atmosphere and come down again as liquid (rain) after condensation.

      Hi #Love Turquoise,

      Following on from Annes answer. Its possible that it rains on at least two celestial bodies other than Earth in the Solar System:

      Venus: The atmosphere is so dense that even with the heat it may well rain Sulphuric Acid in the upper atmosphere.

      Titan: The atmosphere is also dense but it is really cold here. Its likely that it rains Methane and that this forms puddles or little lakes on the surface!

      But I wouldnt recommend “Singing in the Rain” in either case!
