It is the things it hits which are visible - think of X-rays

So until it bounces it is invisible?

"Light" is only seen/perceived when it bounces off something or passes (or is bent through) something. Space is a vacuum - there is nothing there, there is no atmosphere. We only see light when it bounces off another planet or star, or some dust, or a satellite, or a martian, or a dog in a space capsule, or Mr Spock, or Blake's happy band of comrades aboard the Liberator etc etc

I think it might be something to do with the way we pick up light. Possibly it is there but we can't perceive it, because of the way our eyes are constructed, without it being brought to us by atmosphere.

Ive a strange question,some one might know the answer.

This planet earth is a sphere as has been demonstrated in so many ways.We have even seen it from space.
It rotates on its axis every 24 hours while orbiting the sun every 365 days.

One side of this planet is in darkness while the other half is day light.

Why is it that when we get beyond earth's atmosphere all is darkness, the only things visible being the sun and the other stars. IE darkness between sun and earth?

Is the light that illuminates earth invisible? Apologies if its a stupid question.
