Question
Why does the sky appear dark instead of blue to an astronaut?
✓
Answer
The sky appears dark to the astronaut because in outer space, there is no atmosphere to scatter the sunlight. Since there is no scattering of the blue component of the white sunlight which can reach the eye of an astronaut in outer space, the sky appears dark to the astronaut, instead of blue.
