1. Why Is the Sky Blue? | NASA Space Place – NASA Science for Kids spaceplace.nasa.gov

   Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This ...

2. Why Is the Sky Blue? | NESDIS | National Environmental Satellite, Data, and Information Service nesdis.noaa.gov

   Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

3. r/askscience on Reddit: Why is the sky blue? Do I understand it correctly: reddit.com

   Honestly it looked like the eye of sauron in the sky. I wonder what it would take to scatter every last bit of sunlight? ... This is all described via Rayleigh scattering, which states that the amount of scattering light undergoes is inversely proportional to it's wavelength ... Two factors. Sunlight has less purple light in it, and our eyes are less sensitive to purple. So while the fraction of purple photons that get scattered is larger than the fraction of blue photons, the absolute number of blue photons that enter the atmosphere, get scattered, and simulate our eyes to produce the sensation of color are greater than the absolute number of purple photons.

   He discovered that when light passes through a clear fluid holding small particles in suspension, the shorter blue wavelengths are scattered more strongly than the red. This can be demonstrated by shining a beam of white light through a tank of water with a little milk or soap mixed in.

5. r/explainlikeimfive on Reddit: Eli5: why is the sky blue? reddit.com

   ELI5: air molecules deflect/scatter light sometimes, and the angle that they deflect it at is proportional to the frequency of the light. Blue light is deflected the most, red the least. When you look up at the sky, you're seeing the blue light ...

6. Why is the sky blue? | National Geographic Kids kids.nationalgeographic.com

   Slowly, over the next two billion years, oxygen in the atmosphere rose to its present levels, and the sky took on the blue hue on view today. The light shining from the sun is made of all the colors of the rainbow, and each color travels on ...

7. Why is the sky blue? | Royal Observatory rmg.co.uk

   It’s because human eyes are actually more sensitive to detecting blue light, and more of the sunlight coming into the Earth’s atmosphere is blue rather than violet. Small air molecules in the Earth’s atmosphere scatter the sunlight during the day to give us a blue coloured sky

8. Why is the Sky Blue? | Montreal Science Centre montrealsciencecentre.com

   So, when we look up at the blue sky, what we’re actually seeing are those blue wavelengths that have been dispersed more than the others across the atmosphere. At night, when the white light of the Sun is not visible, the sky reflects no colour at all. That's why it looks black!
