Why are all those stars in the sky?

My grandmother used to tell me, they are the eyes of angels watching us!

Except for stars nearest the Pole Star, all stars move in one single direction all the time --- east to west. This isn't because the stars are moving but instead because Earth is rotating.\n\nIf you're seeing stars moving 'rapidly' and 'sporadically' you're either not observing stars, or you should tell me where you're gettin' that good stuff :)

There are stars in some, but not all of the photos.\nStrong lighting causes the stars to get underexposed, and that is why you can't see them.\n\nIf you have any reason to doubt our landing on the moon ask the Russians (Who had their own lunar program) if they believe it.  They had many spies, and would have benefited greatly if the moon landing was in fact a hoax.

sky is just a small portion of the universe.\nit cud have a pillar if one cud go to the ends of the universe.. but even the most elaborate and sensitive radio telescopes cant reach all that is up there.. \n\nthere are more stars and galaxies un-named...... and counting....\n\nil let u know once i found out what makes the sky stands up there... with or without pillars. \n\nafter a million light years.....P

Not necessarily.  A star is only a sun if it has planets around them.  But all stars look like suns.

You can see many of them with the naked eye, and some of the get pretty darn bright.  You can even see the inetrantional space station when it passes overhead.  Of course any of these objects will jusst look like a star moving across the sky at a decent rate.  But it is pretty cool.\n\nhttp://www.heavens-above.com will tell you exactly what is visible from your location on any night, as well as where to look.  You'll need a little bit of amature astronomy knowledge (magnitudes, reading a starchart) to get much out of it, but it is an awsome resource for this kind of thing.

There are more stars than we can count.  Most of them have planets.   Most of those planets have moons.

Mainly because the sun is so much closer than any other star. The twinkling effects our atmosphere causes on other stars is simply overcome by the brute force of sunlight.\n\nDistant stars twinkle due to Earth's atmosphere, but then why don't planets also twinkle; they look to be about the same size? Here's a good explanation I cut-and-pasted for you from an astronomy website --\n\n"Just like a computer screen, your eye is composed of a certain number of 'pixels,' each represented by a single light-receptor cell in your retina. If two (or more) points of light are close enough such that they are focused on the same receptor cell in your eye, you will experience them as a single point of light. This is the 'resolution' of your eye. \n\nNow, a star on the sky is in a true sense a single point of light. All the light comes through the atmosphere in exactly the same direction, through exactly the same atmospheric turbulence, and thus is bent in exactly the same way. So when it gets to your eye, the amount of light you see varies. It also strikes (primarily) only a single receptor ('pixel') in your eye. \n\nOn the other hand, light from a planet is different. Each of a few receptors in your eye sees a large number of light rays coming from the planet, each of which has been bent differently by the atmosphere (since the planet has size on the sky, they are arriving in slightly different directions). Some of these rays will become brighter, some dimmer. But because they all illuminate the same receptor in your eye, that receptor only sees the total amount of light hitting it. There will be about the same number of enhanced rays as dimmed rays, so you experience a steady light, not a twinkle."

A star is any massive gaseous body in outer space, just like the Sun. Unlike a planet, a star generates energy through nuclear fusion and therefore emits light. All stars except the Sun appear as shining points in the nighttime sky that twinkle because of the effect of the Earth's atmosphere and their distance from us. The Sun is also a star, but it is close enough to Earth to appear as a disk instead, and to provide daylight.

The scientific name for the twinkling of stars is stellar scintillation (or astronomical scintillation). Stars twinkle when we see them from the Earth's surface because we are viewing them through thick layers of turbulent (moving) air in the Earth's atmosphere. \n\nStars (except for the Sun) appear as tiny dots in the sky; as their light travels through the many layers of the Earth's atmosphere, the light of the star is bent (refracted) many times and in random directions (light is bent when it hits a change in density - like a pocket of cold air or hot air). This random refraction results in the star winking out (it looks as though the star moves a bit, and our eye interprets this as twinkling). \n\nStars closer to the horizon appear to twinkle more than stars that are overhead - this is because the light of stars near the horizon has to travel through more air than the light of stars overhead and so is subject to more refraction. Also, planets do not usually twinkle, because they are so close to us; they appear big enough that the twinkling is not noticeable (except when the air is extremely turbulent). \n\nStars would not appear to twinkle if we viewed them from outer space (or from a planet/moon that didn't have an atmosphere). \n\n\n---------------------------------------------------------------------------------\nStars, except for the Sun, although they may be millions of miles in diameter, are very far away.  They appear as point sources even when viewed by telescopes.  The planets in our solar system, much smaller than stars, are closer and can be resolved as disks with a little bit of magnification (field binoculars, for example).\n\nSince the Earth's atmosphere is turbulent, all images viewed up through it tend to "swim."  The result of this is that sometimes a single point in object space gets mapped to two or more points in image space, and also sometimes a single point in object space does not get mapped into any point in image space.  When a star's single point in object space fails to map to at least one point in image space, the star seems to disappear temporarily.  This does not mean the star's light is lost for that moment.  It just means that it didn't get to your eye, it went somewhere else.\n\nSince planets represent several points in object space, it is highly likely that one or more points in the planet's object space get mapped to a points in image space, and the planet's image never winks out.  Each individual ray is twinkling away as badly as any star, but when all of those individual rays are viewed together, the next effect is averaged out to something considerably steadier.\n\nThe result is that stars tend to twinkle, and planets do not.  Other extended objects in space, even very far ones like nebulae, do not twinkle if they are sufficiently large that they have non-zero apparent diameter when viewed from the Earth.\n-------------------------------------------------------------\n\n\nI can be more specific, sure. Remember that just like a computer screen, your eye is composed of a certain number of "pixels," each represented by a single light-receptor cell in your retina. If two (or more) points of light are close enough such that they are focused on the same receptor cell in your eye, you will experience them as a single point of light. This is referred to as the "resolution" of your eye, or any telescope for that matter. \n\n\nNow, a star on the sky is in a true sense a single point of light. All the light comes through the atmosphere in exactly the same direction, through exactly the same atmospheric turbulence, and thus is bent in exactly the same way. So when it gets to your eye, the amount of light you see coherently varies. It also strikes (primarily) only a single receptor in your eye. \n\n\nOn the other hand, light from a planet is different. Each of a few receptors in your eye sees a large number of light rays coming f

gravity is everywhere - even in space.  what do you think holds everything together, keeping jupiter from sailing off towards alpha-centauri?  \n\non to your question - shooting stars are not stars, they are meteorites - varying sized "rocks" that are orbiting whatever has them stuck in a gravitational orbit until they encounter the earth's atmosphere, and burn up, which is what you see and call a "shooting star."  most never hit the ground, but when they do, look out!

when the light from the stars enter the earth's atmosphere, the light wave bends and refracted until it reach our eyes. So because it is refracted, when we look at it, it seems to be twinkling.

Well it's impossible to see stars when the sun is up, and Venus is the only planet visible during the day, so there is no way all those bodies could have been visible at the same time. There might have been some sort of alignment, but it would only have been calculated, not observed.

None, they up in the Sky, best seen at night. The Earth does revolve around a Big Star that can actually be seen in the day and not night. Make for a good Word Play/Riddle question. ;-D

The sky is (roughly) that part of the atmosphere or of outer space visible from the surface of the earth (or any other planet; see Skies of other planets). Birds, airplanes, and kites are often considered to fly in the sky. It is difficult to define precisely for several reasons. During daylight the sky has the appearance of an opaque blue surface, but this is the result of the air scattering sunlight. [1]There is no "blue object" above the earth in any normal sense, so it is hard to say what object the sky is. The sky is thus sometimes defined as the denser gaseous zone of a planet's atmosphere. At night the sky has the appearance of a black surface or region scattered with stars. But if we then say that the sky is the entire visible universe, it would not be the same thing we see during the day. The color of the sky is a result of diffuse sky radiation. On a sunny day the Earth sky usually looks as a blue gradient — dark in the zenith, light near the horizon (due to Rayleigh scattering). It turns orange and red during sunrise and sunset, and becomes black at night.\n\nDuring the day the Sun can be seen in the sky, unless covered by clouds. In the night sky (and to some extent during the day) the Moon, planets and stars are visible in the sky. Some of the natural phenomena seen in the sky are clouds, rainbows, and aurorae. Lightning can also be seen in the sky during storms. As a result of human activities, smog during the day and light radiance during the night are often seen above large cities (see also light pollution).\n\nIn the field of astronomy, the sky is also called the celestial sphere. This is an imaginary dome where the sun, stars, planets, and the moon are seen to be travelling. The celestial sphere is divided into regions called constellations.\n\n\nSky in religion\nMany cultures ascribed strong religious qualities to Earth's sky, believing it to be the home of the heavens and various deities. Among the Chinese, in certain situations, sky means god. For example, people may say "They became friends after several fights: this is the idea of the sky" or "Why does the sky always fool me?" Some religion and art historians believe that in Christianity, in particular, the connection between heaven and sky arose because of a medieval painting technique, where different places were drawn separately on the same picture. Heaven, a different and more important world, was usually painted above the earthly world and was separated from it by clouds.\n\n\nExpressions\nA pie in the sky is something that is wanted very badly but is unobtainable. \nWhen someone's assumptions or premises concerning a particular subject seem to be radically different from everything you know and recognize about the world, you wonder what color the sky is in their world. \nSimilarly, because the blue hue of the sky during daytime is such a universally observed and understood phenomenon, people say "as sure as the sky is blue" to mean that something is an indisputable fact. \nBlue skies are evoked as a symbol for good times, optimism and emotional peace. \nTo be sky-clad means to be in the nude. \nSimilarly, to go skying is a euphemism for stripping or streaking. \nTo show that there are no limits on what we can discover or accomplish, you can say, "The sky's the limit!" \n"Blue sky thinking" means coming up with a host of ideas without being restricted to what is practical (similar to brainstorming); in particular, an optimistic assumption is made that there will be no obstacles or opposition to implementation of the ideas. \n"The sky is falling" is a common expression that is used when any sort of disaster is occurring. This came from the fable Chicken Little

yeah...ive heard this too when i was a kid, but i guess its all BS. hw can u see stars? i mean, even at te bottom of the well ud still be looking at the sky and the sky is all bright from the sun, right?\n\nbut if u slipped and fell into a dry well, ud probably hav stars, birds and stuff twittering and revolving all around you, like in the cartoons.

It's the same reason stars twinkle--light traveling through the atmosphere gets distorted and flickers.
