The masking effect of the sky scattering of visible light in daylight.


 Why the stars are not visible in daylight?
 The sky scattering of visible light is the reason, this scattering cause a masking effect not only in the stars but in any object located in the atmosphere, this effect not always block/mask completely the objects as in the stars but always decrease the clarity/contrast with what that object would be seen without that masking effect.
 This masking effect is lower in the infrared and even lower in the short radiowave section of the electromagnetic spectrum.
