Question

Why does the sky appear dark instead of blue to an astronaut?

Answer 1

Explanation:

The sky appears dark instead of blue to an astronaut because there is no atmosphere in the outer space that can scatter the sunlight. As the sunlight is not scattered, no scattered light reach the eyes of the astronauts and the sky appears black to them.

Answer 2

The sky appears dark instead of blue to an astronaut because,the sky has no colour.

But when the atmospheric particles scatter the sunlight the blue rays are emitted that's why we see blue sky from our planet.

But in the outer space there is atmosphere and the scattering of light rays happens.

That's why the astronauts in the outer space see dark sky instead of blue sky.
