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 5 лет назад

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 5 лет назад

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

@anupamayogeshkumar7580 3 года назад

*Question:* Light reflected off spherical objects always concentrates at a point, it doesn't evenly illuminate the whole spehere. Why dont the planets (or moon) ever adhere to this? *Example:* 🪀🟣 See the top of there emojis. The artist added white highlights to show they are spherical. Look around your room for spherical or cylindrical (like a soda can) and you'll see the same concentration of light .

@tattooedgirl22 6 лет назад

Thank you thank you thank you! I have watched several videos on this topic but yours is the only one that explains it plainly and gives a great visual that is very comprehensive! LOL I have been looking at the stars since I was little almost every night and the stars closer to the horizon look like they are flashing red white and blue colors and now I know why. For the longest time I thought maybe they are not stars. I know that kind of sounds funny but they were just so completely different then the rest of the stars in the whole entire sky it just seemed weird. But now I have a clear understanding of why they look that way. So thank you once again :) Could you maybe do a video of why they flash red white and blue? That would be amazing!
