If anyone answered my question on stars, could you also answer this one.?

Question

Alot of you said that the stars where always there.
Well why is it some nights from my house i see alot of stars,
then sometimes they are far less or far more?

Answer 1

you see different stars depending on what season it is, because the earth is traveling around the sun making a full circle in one year. if you think you see more stars in the winter it is because there are more bright stars in winter but not nessicerally more stars just more bright ones. you probably live in a city where the street lights and porchlights drown out some of the stars just like the sun does. go to where it is dar and you will see alot more stars. even better is if you do it in the summer...go to a really dark spot and you will see the entire sky lit up with stars!!!! good luck...keep lookin up!!!

Answer 2

Some of your answerers need to take a lesson in astronomy. At any given location in the worlds, the stars you seen tonight will be the same stars you see tomorrow, taken into consideration, atmospheric conditions and ground lighting. It is true that the stars you see in winter will be different than the stars you see at summer, but this shift is gradual and is due to the rotation of the earth around the sun. If you are a star gazer, try to arrange a trip to the country side or some location far from city lights to truly view the night sky. You'll be simply imaged at the number of start you will see.

Answer 3

There are many good answers here. As a member of a local astronomy club I can also add that it takes about 20 minutes for your eyes to adapt to the darkness. (A bit less for young people, a little longer for older folks). If you look at a bright light, then look back at the sky, a lot of stars will have disappeared.

Also, the moon drowns out stars. Full moon nights have far fewer stars in the sky than no moon nights.

Answer 4

The number of stars in the sky also depends on your location. If you live in a city, you will see a lot less stars due the huge amounts of light generated in your area. Also, the earth orbits around the sun. Therefore you don't see the same stars every night. To you, it looks like they shift across the sky each night. Some months you will have more stars than other months.

Answer 5

It's like when it is clear day you can see for ever likewise when the sky is bright and clear at night you can see millions of stars twinkling in the sky. And the further north you live the greater chances are of this happening.

I lived in Shetland for a long time and the night sky was truly amazing. Most nights the sky was just full of stars and when there was a full moon well it was something else. And I could wax lyrical about aurora borealis for hours.

Answer 6

Firstly, the stars have not always been there: most of the ones you see formed well after the big bang that started it all some 14 billion years ago. Secondly, visibility changes due to many changing conditions: ambient light (including moonlight), haze in the atmosphere, and temperature gradients in the atmosphere.

Answer 7

the atmosphere might have a little more cloud cover, or there might be more pollution on some days. Also, while the earth rotates, it faces different parts of the universe. Since some stars are closer than others in different locations of the rotation, there might seem to be more. Generally, the latter only happens during different seasons.

Answer 8

Some parts of the sky are more "starry" than others.

Firstly, you may be looking at different times. (You do of course realise that the stars rise and set with the turning of the Earth, and therefore over a couple of hours you will be looking at a different set of stars?).

Secondly, because of Earth's passage around the sun (I hope you also realise that takes a year), you see different parts of the sky at different times.

But if you look at the sky at 9pm one night, the stars will be in pretty much the same position in the sky at 9pm the next night. However, things will look somewhat different at midnight, and very different at 3 am.

It will also look different at 9pm six months later.

Answer 9

there will be more or less depending on the time of evening. if you watch the sky for hours at a time you will notice that everything moves. especially if you watch the Sagittarius band of the milky way, that is where you will see the most stars. the Sagittarius band is one of the spiral arms of the milky way galaxy. plus you will not be able to see the Sagittarius band all year long.

Answer 10

The full moon can wash out some of the dimmer stars as can city lights. On nights of no moon, you can see far more stars.
