why a starry night is so dark?

Question

since stars we can see are about 5000 and most of theme are bigger than our sun,how comes that the night sky isn't bright?

Answer 1

If you would be on the moon during a moonday, you would see the sky as black, seeing the stars, earth (maybe), and a very strong light source, with a seemingly smaller diameter than the sun as seen on earth. The shadows are dark, you cant see anything. The difference with earth is caused by the absence of an atmosphere.
On earth, UV light from the sun is absorbed by the outer layers of atmosphere, and transformed into visible, blue light.
Due to the distance, the light energy of the stars or the moon when reaching earth, is weaker than the minimal energy required to excite the atoms of the gases in the atmosphere, thus there is no sky or opaque "filter" being created.

Answer 2

More like, it is dark that's why it's a starry night. You don't see most of the stars (the ones that are much farther away) when you are near city lights, or when the moon is bright. When those lights are gone, for example in a campsite where there is little to no light, then you see what seems like quadrillion stars.

Answer 3

Its the other way around. You can see the most stars on a dark night, so its a starry night because it is dark. The stars don't light up the sky because they are too far away.

Answer 4

The stars are infinitely more far away than our sun is. Plus some of those stars are dead ones and don't give as much light as an active star.

Answer 5

On regular night you usually see the moon which reflect our sun's light. Our sun (from our point of view) is much brighter than any other sun.

Answer 6

because most of the strs are too far away. since there is almost nothing in space the light can travell long distances so the light from stars can shin from millions of miles away

Answer 7

The Sun is facing the other side of the planet.

Answer 8

Because They are SO far away that the amount of light it takes just to get here is only enough for them to show themselves.

Answer 9

Sure. 'cause the moon is not a new moon and the earth is blocking the sun. That's why it's called nighttime.

Answer 10

to see the stars more clearly you need to lose the surrounding ambient light (man-made light i.e streetlights etc ),when there is little or no ambient light around the stars seem brighter but it seems darker around you. hope this is what you meant.
