On a clear, dark night, the sky may appear to be ';full'; of stars. Does this appearance accurately reflect the way stars are distributed in space? Explain.On a clear, dark night, the sky may appear to be ';full'; of stars. ?
Not really. First of all, everything in the universe is very far away from one another. Light years away. A light year is how far light travels in one year. The closest star, Proxima Centauri, is about 4.2 light years away. This means if I were to point a telescope at it right now, I would see what it looked like 4.2 years ago. So if it exploded when I was watching it, I wouldn't know about it for another 4.2 years. Now, there's another star called ';Sirius'; which is around 8.6 light years away. Now, I'm not viewing Proxima Centauri and Sirius as the were at the same time because the distance between them is so great. One could have moved half way across the sky, and I wouldn't know about it. And the distances among other stars are even greater than this.





Also, cosmic dust and the thick gases in our atmosphere scramble the light we do get and often block our views of some of the fainter stars.On a clear, dark night, the sky may appear to be ';full'; of stars. ?
Most of the stars you can see at night are actually close neighbours to us in the Milky Way - a few hundred light-years away at the most. The Milky Way itself gives you a view a little further, due to the sheer number packed together in the plane of the galaxy's disk, but sight is quickly blocked by dust clouds, so we can't actually see the centre of the galaxy.





If you take the long view, space is mostly empty, with most of the mass gathered into galaxies that are scattered more or less uniformly throughout the universe.
Stars are always there, say few billions. As you know, on day time, due to sun light, we are unable to see stars. On the other hand, on a clear dark night, we are able to see light emitted from stars. Remember, sunlight takes 8 minutes to reach earth, which means sun is 8 light minutes away from earth. Like wise, majority of the stars or galaxies(collection of stars) are many light years away. Earth which is spherical in shape make the sky view spectacular, we view many stars distributed, though they are at very great distance, even beyond our imagination. Please understand, location of stars are not exactly as we see because of defraction(bending of light rays) thru atmosphere. That is why we have telescope in outerspace.
No, because there are extensive clouds of dust and gas which block our view of much of our galaxy.
