Question

nah sometime at night with clear sky right i dont see no stars??

Answer 1

Wisdom, obviously you know that the stars are always there, even in the daytime.

So, you want to know why, at night, sometimes we can see the stars and sometimes we can't see them.

I always look for the stars; I think they are beautiful. Sometimes, when we are looking at the light from a star, that star is already dead; but because of how long it takes the light to get here, we still see the light.

I find that fascinating — the star is gone, but its light still shines.

Anyway, you know the scientific answers: clouds cover the stars; a full moon makes too much light to see the stars; if you live in a bright city, it's too difficult to see the stars; smog & pollution can block one's view of the stars.

But you are saying that even on a clear night you sometimes can't see the stars.

Sometimes it looks like a clear night, but very, very high above us, in the atmosphere, there is moisture, sort of a haze. It is too high for us to see it, but it will block the light of the stars.

Also, as you know, the earth is revolving around the sun. That is why on different nights, the sky will look different (and at different times during the night). Star patterns we see one week may not be there the next week.

And also, depending on the angle of the earth, we may see millions of stars at one time, but at another time it may look dark. We are passing by an empty space. Maybe the stars in that space are so far away that their light has not reached us yet.

Or maybe we were sleeping, and we missed them :)

Answer 2

You can see about 2,000 stars with the naked eye. The pattern of stars in the sky is fixed, but seems to rotate (turn) through the night sky as the Earth spins. That's why you think that there are no stars. It takes 23 hours 56 minutes for the star pattern to return to the same place in the sky. As Earth orbits the Sun, our view of the stars changes and the pattern starts in a different place each night. Different pattern of stars are seen in the northern hemisphere and southern hemisphere.

Answer 3

Besides sometimes being cloudy, sometimes not? Or, sometimes there is a full moon, making it more difficult to see the stars? Of course, there is location: if in a city, viewing stars would be almost out of the question, but if in a remote location, the stars will appear bright. Of course, the temperature of the air affects the viewing: cold produces sharper, clearer images than hot weather; drier air produces better images than humid air.
Also, as the earth revolves around the sun, we get different views of the heavens; sometimes we see a great view of the galaxies, other times we are looking into the "emptiness" of space.

Answer 4

There are always stars in the sky, even during the day. You just can't see them because of the other light in the sky (the sun). At night, things like clouds, street lights, the moon, or smog can make it harder to see stars.

In a cloudless, remote region (like desert), you can see more stars than you'd believe from living in a town or city.

Answer 5

because of light pollution around us. When there is a lot of light in the sky at night created by street lights, general light sources etc. you can't see the stars. Kind of like when the sun comes out, the stars are still there but because the sun emits so much light we can't see them.
Does that make sense?

Answer 6

Well it depends on the whether and also if you live in a big city do to the lights. If it is cloudy then the clouds hide the stars, I love to just be outside and star up at them. They are so magical.

Answer 7

Because they're clouded either by clouds (which you won't see because they're not lit up, being night time and all) pollution, or light pollution. You're much more likely to see stars out in the countryside than in a city.

Answer 8

The stars are always there, but sometimes the ambient light or smog from the surrounding city will block your view of the heavens.

Answer 9

You can't see stars at night when there are clouds and it's dark.

Answer 10

some nights the clouds cover the stars, and if not, the moon is just so bright that the stars are unseeable.
