Why is the sky blue and not black like space

[From: ] [author: ] [Date: 11-05-25] [Hit: ]
So the light that get finally reflected down from the scattering is blue, therefore causing the sky to appear to be blue. This is called due to the scattering of rays from the Sun. The specific chemical compositions which make up the light from the Sun such as nitrogen, hydrogen, and helium combined with the oxygen of the Earth combine to make the sky appear blue.......
WHYYYYYYYYY SPACE IS BLACK SO WHY ISNT THE SKY BLACK?

The sky is blue because the molecules in Earth's atmosphere scatter light in the shorter yet more direct wavelengths of blue light mostly due to the amount of nitrogen atoms in the atmosphere which is blue, especially on a star, while higher wavelength light on the red end of the spectrum goes through to the ground because the Sun refracts the molecules of light so much that it travels so fast and too fast for our eyes to detect. It goes to the next place it can. So the light that get finally reflected down from the scattering is blue, therefore causing the sky to appear to be blue. This is called due to the scattering of rays from the Sun. The specific chemical compositions which make up the light from the Sun such as nitrogen, hydrogen, and helium combined with the oxygen of the Earth combine to make the sky appear blue. In space, we are farther from any star, so the sky appears black because black is the absence of color and no light is being directly refracted in your eyes. Hope I helped!

The sky is blue because the molecules in the air scatter light in the higher wavelengths (that is, the blue light), while lower wavelength light (that is, the light on the red end of the spectrum) goes through to the ground. So the light that get finally reflected down from the scattering is blue, therefore a blue sky. This is called Rayleigh scattering.

As usual, I'm one who ends up correcting every one else's mistakes.

Red light IS NOT scattered into the ground, as others have claimed. More about that later

The diameters of N2, O2, O3 (ozone), CO2 molecules and argon (Ar) atoms in the atmosphere are approximately equal. When a ray of sunlight with a frequency and wavelength of blue-green (Whoa!
Keep your cursor off that thumb down button. I'll explain THAT as well.) slams into an air molecule (not an H2O molecule), it gets reflected off in all directions, including toward the ground. This is why a cloud free sky is turquoise blue for most people. At night the sky is transparent, so, as long as there are no or few clouds, the sky is black to very, very dark navy. This is Rayleigh scattering.
