you cant actually see rays of light from the side.
you can only see light when it goes directly into your eye and hits your retina.
So at night, you cant see any light because you cant see the sun directly. the rays of light are blocked by the earth.
When you are looking at a ray in the earths atmosphere, (perhaps at sunset, or when the sun shines through a hole in the clouds) you cannot see the actual light ray... you are looking at the light that bounces off the particles in the atmosphere, and those rays do travel straight into your eye, just like the light bouncing off the moon. Think of the dust/mist in the atmosphere as millions of tiny moons.
At night in space... there is no atmosphere, and no particles or dust for the sunlight to reflect off.... so you cant see it even though it is there.
