Why can you only see shooting stars for a few moments?
Shooting stars are not stars at all. They are tiny bits of debris, usually rock or dust. They completely burn up in our atmosphere (most of them) and so when you see one 'vanish', it is, in fact, gone.
Are the stars that you see at night really present when you see them?
Yes. There is a common myth that the stars you see at night have burnt out in the millions of years it takes for their light to reach us.This is not true for two reasons.The stars you see at night are in usually no more than a few hundred light years away, so you see them as they were, at most, a few hundred years ago.Most stars last for billions of years, so a period of a few million years, let alone a few hundred, is not significant.
Can you see the stars in sao paulo?
Only at night, and outside. Although Sao Paulo has the same problems with seeing stars as any city does; the city lights are so bright that you can only see the brighter stars.
Why do we see star at night?
we only see stars in the sky at night because in the day it is light because of the sun. The stars are very light but the stars can not be seen because of the sunlight. So when it is pitch black you can see the stars so the stars sparkle in the sky without no light showing so its just the stars and the moon lighting up the world!
Why are stars always there at night?
Stars are there day and night. During the day the sun, which is a star, is so bright that you cannot see the other stars. So that is why we only see stars at night. As we orbit the sun we do see different stars throughout the year. So ones that are not visible on a particular day will be visible at night at another time of the year.
How many red dwarf stars are there?
Impossible to answer because they are dim stars so we can only see the close ones.
When our eyes see stars have some of them have actually disappeared?
No. It is commonly stated that the light we see from the stars left them millions of years ago. This is not true. All of the stars you see in the night sky are, at most, a few hundred light years away. The closest of them, Alpha Centauri, is a little more than 4 light years away. So you see the stars as they were, at most, a few hundred years ago. A few hundred years is insignificant in the lifetime of a star.
Why do you see the sun in the day and you dont see the others stars?
because the light from the sun is so close to us and so bright it blocks out the light from the other stars. The only time you can see light from other stars during the day is during a solar eclipse.
Are stars countable?
Yes and no, as there are a huge amount of starts. Only a few thousand stars can be seen by the naked eye. You can count those. Every star you see is in our galaxy and there are many more stars in our galaxy that you cannot, about 100 billion. Then there are billions of other galaxies. So we can estimate the amount of stars in the universe, but not count all of them.
Why can you only see stars during a total eclipse of the sun?
Because the sun is blocked out, so it is like night, but it is not totally dark. When the sun is out it is too bright to see the stars.
Why do we see other stars as only tiny spects in the sky?
Because they are so far away.
Why does the five dollar bill have 20 stars on it?
