Amazing explanation ... I understood the concept very well ... The example with the dots ath the end was very good

[@pranavkoka8597]

I've seen the video: Why is the sky blue, but can you clarify my doubt.
Why do astronauts looking from space don't see the blue colour of the sky.
Blue light does get scattered in the atmosphere, so, ideally everyone should see the sky to be in blue in colour no matter where they look from (unless it is night because there is no sunlight).
Can you please answer it as quickly as possible. (It is a question in CBSE class 10 too)

[@palak6981]

The sky for an astronaut is not the same as the sky for a person on earth. His sky is overhead, which is just empty space.

[@ritz2156]

Pranav Koka there is no atmosphere in the sky to scatter the light if there is no atmosphere that means there is no nitrogen or any form of air molecules is present so there is no scattering of light
