Question

Explain why an astronaut in space finds sky to be dark

Answer 1

The sky appears dark instead of blue ta an astronaut because there is no atmosphere containing air in the outer space to scatter sunlight.As there is no scattered light to reach our eyes in outer space, so, the sky appears dark.

Answer 2

The astronaut finds the sky to be dark from the space because there is no atmosphere in the space and without atmosphere there is no scattering of light.

Here we have an atmosphere and light gets scattered that is why we see a blue sky.

The layer of air is the reason for scattering.So in space astronauts see a dark sky.
