Hello, I have a novice question. I know that the sky color is blue (at noon, when there is no clouds), because the air particles (mostly N2 and a little O2 ...and other) scatter short-wavelength light more than longer wavelengths. That is why we can't see the stars trought the atmosphere in daytime (the scattered light is with much more intensity then the light emmited from the brightest star). The question is why the stars can see us? All the pictures taken from above the atmosphere show the landscape of earth trought the atmosphere, where in the landscape is noon.
