Question
Why do Sun get brighter in Noon then in early morining?
Hi Vinoba,
The sun appears brighter around noon because the sun's rays are most direct then. At noon, they reach us through the least amount of atmosphere, which contains a lot of dust and moisture, both of which absorb some of the light. That's the same reason we see very few stars close to the horizon, but lots of stars overhead. Living on earth, with a thick atmosphere, we have to put up with the absorption of light. But if we had an observatory on the moon (which has no atmosphere), the sun (or the stars) would be equally bright no matter how far up in the sky they were.
Hope that helps.
