We're in space, so why can't we see a constant black sky, with bright day stars other than the sun and planets

Because we are really close to our star, the sun.  The light from it drowns out the other lights from stars.  The same way a very small light in a room is drowned out by turning on a much larger one.  At night, we are completely turned away from it, so we can now see other lower light sources.

cause we cant see the other side its dark

The healthy human eye is only restricted by external factors (ie.: poor visibility due to haze, dust or fog), just think how far the stars are!

stars have a life span as well, they are born and they die. but these processes could take  millions and even billions of years to happen.they are also very very far away from us.\non a cloudless and moonless night, you may see that the sky is full of them. on a bright moonlight they seem to be less numerous. but on any given time there is about 4,000+ of them that can be seen by the naked eye. these is still true as it was since ancient times. the fact that you seem to see a lesser number of them may be due to the effects of bright city lights were you are living. bright ground based light have a dampening effect to star lights at they are viewed by the observer. if you want to see lots of them, i suggest that you go out far from the city where it is dark, provided the sky is not cloudy and that there is no moon in sight.

Most of the stars we see with the naked eye are within our galaxy.  If you lived in the southern hemisphere, you could see the Mangellanic clouds, which are two small satellite galaxies of the Milky Way.  You would not be able to see induvidual stars, but you would see the glow of millions of stars within them.\nIn the northern hemishere, if you are in a very dark place, you can see the Andromeda Galaxy, which is 2.5 million light years away but you can see the glow of the billions of stars that make up that galaxy.\nBut all the induvidual stars we see in the night sky with the naked eye, they are within our Milky Way galaxy.\n\nAnd for stars between galaxies...yes there are.  There are a few stars that get cast off and tossed into intergalactic space.  There is one right now that has been flung out of our galaxy at a bit over a million miles an hour when it had a close encounter with the black hole in the core of our galaxy.  There are millions, perhaps billions, of stars in the galactic halo around the Milky Way...they are just difficult to see, even in a big telescope, as they are mosly dim red dwarfs.  The space between galaxies is not empty...things are just spread out a bit more.

The light from the stars is distorted by charged particles and dust in our atmosphere which is in constant motion, hense the twinkling.

Blinking/flickering stars are due to our atmosphere. But more importantly, due to heat rising from the earth's surface.\n\nIf you were in space, the stars would be constant, since the medium is practically  a vacuum and the light rays are not refracted. However, once you enter our atmosphere, the air medium will cause the white light from the stars to be refracted into different colors.\n\nHowever, when heat rises from the earth, esp at night, the air will have varying refractive indices. Hence, the light from the stars will be refracted more at different times, causing the flickering.\n\nAnother example if this is if you are looking at a bright light in the distance, close to the horizon on a hot day. Most definitely you would see the heat rising from the earth, and the light would be slightly flickering also. In addition, if you are atop a hill at night, looking down at a city or town, its lights would also be flickering. It is the same principle here that applies to the blinking stars.\n\nI hope this helps.

there are places where there are no stars, just because they can be so far apart, and there are also stars that are so far away, or not very bright that can't be seen from earth, then of course there's all that light pollution that blocks many stars from being seen - go to a city ur lucky if u see one, but out in the country........ its beautiful

No, because a black hole is a collapsed star, and the closest star to us, besides the sun, is thousands of light years away. They also suck in EVERYTHING including light and destroys it.

This is an illusion. The aperture used on cameras in space is so small as not to allow enough light in to be able to see the stars. Try using a video camera to video the night sky on earth, you will find that you won't see the stars then either. \n\nDon't worry, the stars don't disappear when you get to space.

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."

They are black and full of stars.

You can't see the stars during the day due to a process call Rayliegh scattering.\nBasically the sun radiates many visible colours of visible light even though it looks yellow. The blue light that the sun radiates is scattered by the atmosphere in all direction whilst other colours are unaffected. This gives the sky a blue appearance during the day. The blue sky is much brighter than the stars and thus we cannot see them.\nStrange fact: It is because the atmosphere is mostly nitrogen that the sky is blue, if the atmosphere was mostly oxygen it would be green.

Even on a cloud free night the atmosphere will still affect the infra red light as it descends to earth.\n\nEarth;s air is continuously moving, a ray of starlight is refracted in a random direction causing the star we see to twinkle. This twinkling is extremely irritating to astronomers as it blurs the images from telescopes, leaving the resolution of the largest observatories no better than that from a 10cm telescope. (Larger instruments are built to collect more light, producing brighter images but with the same resolution). The only way to entirely avoid this problem is to launch a telescope into space. This is why NASA built the Hubble Space Telescope.

If you go out to the desert or a remote area, away from the city & look into the sky on a clear night, you will see many stars & planets in the sky. If you look into the sky using night vision goggles, you will be absolutly amazed to see over a million times the stars & planets in the same sky. You will see so many "Shooting Stars" you wont know which one to watch. With that in mind, knowing that many stars are out there, & thoses are just the ones you can see, the numbers are in favor of YES. Space is just too vast, there are too many other stars & planets (Billions...Trillions, or more) to think that we are the ONLY ones here. Remember, space goes on......forever.... there is no known "end".

There are more than a hundred-odd 'sun's in our skies, of which our Sun [one of the smallest among these 'sun's] is the closest to us !\nAs the Earth and other planets are in constant orbit around our Sun, it obviously appears to be in the sky ! \n...Incidentally, what we commonly call our 'sky' is also a mere 'mirage', or optical illusion : It only consists of various 'atmospheric' gases [and moisture-laden clouds that float in them], plus an upper ozone-layer - all of which the light rays from the Sun illuminate. \nThis illumination causes us to imagine that there is a blanket-like bluish 'sky' above us ! As the Sun also seems to be 'up there', we say in non-technical words that the 'Sun is in the sky' !

The Big Bang theory offers a resolution of your question (also known as Olbers's Paradox). In a universe with a beginning we can receive light only from that part of the universe close enough so that light has had time to travel from there to here since the Big Bang (about 10 billion years ago). So, even if space extends infinitely far, only a limited region, and a limited number of stars, are visible to us. And the accumulated light from this limited number of stars is not sufficient to spoil the darkness of the night sky.\n\nGod is spelled B-I-G B-A-N-G\nPBrax@netscape.com
