Why cant you see stars during the day or when the sun is out?

Answer 1

Actually, you _can_ see the Moon, bright planets, and bright stars when the Sun is out. To see the planets (other than Venus) and stars in daylight you need a telescope. The stars etc. are there in the sky 24 hours a day, but during the day the Sun's light scattered by the Earth's atmosphere causes the sky to be blue, making them very hard to see. The Moon and Venus are both easily visible in the daytime sky with the naked eye if you know where to look.

Answer 2

The sun is so bright that we cannot see the stars during the day.

Answer 3

Because,the best contrast would likely be from a filter that simply cuts out the blue (more detailed statement requires plugging in numbers and the eye/detector's sensitivity curve). This is related to the frequent observer's strategy of starting in twilight with redder or near-IR filters and working to the blue as the sky darkens and loses the blue scattered sunlight component (and vice versa as dawn impends), which can add an hour to the useful length of a night. For people using digital cameras, this could be very powerful, since their chips have much better IR response than the eye (which resulted in my completely overexposing a shot of the rising Sun with naked-eye sunspot a few weeks ago - it was just barely visible to me through the haze, but so much deep-red came through that it swamped the camera response). For those who remember the fiasco of the Saturn-like image behind Hale-Bopp, that was the same thing -a very red star, aberrated by the telescope optics, which was too faint visually to appear on a comparison chart. Everybody gets burned by passband effects - the best we can do is to only let it happen once. But I digress, and am not sure my license is paid up.

I've picked out maybe three stars naked-eye in the daytime, all from very clear observatory sites (Sirius, Arcturus, and Vega - the stars, not the observatory sites). With our 16" on campus, it's easy enough to show people stars to magnitude 2.5 or so - we can get the brighter component of Albireo, but the other one is tough. (This is in the context of "showing binary stars to class members who won't come back at night"). At our latitude, that leaves Castor as the only workable daytime double star. Hope I helped!

Answer 4

U can if u go down in a well about 40 ft . As long as the sun is not coming down the well ,u will be able to see the stars.

Answer 5

On any nighttime, from nightfall 'til break of day, you will see a million/2 of the sky. it relatively is because of the Earth's rotation. because of the fact it is likewise shifting a splash in it relatively is orbit each and daily, you will see a splash diverse a million/2 of the sky (think of of a one hundred eighty deg. perspective turning by 360 deg. for the period of the year). So the celebs you spot this nighttime would be thoroughly diverse than the celebs you will see 6 months from now, yet at precisely 6 months is the only time that's obtainable because of the fact there is not any overlap precise then.

Answer 6

The sun is so bright, it fills up the entire sky. Its because its so close compared to the other stars.

Answer 7

because the light from the sun is overpowers that from the stars..! =]

Answer 8

During the day, the stars are asleep, they are in bed.

Answer 9

Because they are not bright enough. But you can see the Moon in the daytime because it is bright enough.

Answer 10

They're painted on the other side of the sky, the night side!
