Dust in earth' s air, though very little, scatters the sunlight. This makes the earth's daytime sky blue and the shadow are not completely dark. But on the moon the sky is always black. You would be able to see stars in the daytime. Sunny places on the moon would be very bright. But the shadows would be almost black. The moon has no air or wind to carry the sun' s heat.
