Astronomers can't get a sharp image of our entire galaxy (..the Milky Way..) because we're *inside* it. Those sharp photos you see that are used to represent what our galaxy probably looks like are most often images of the Andromeda Galaxy which is believed to be a kind of twin. Astronomers can also get a pretty accurate idea of what our galaxy looks like by carefully studying what we can see of it from inside, mostly from analysis of the distribution of other stars beyond the sun.

They have used the Hubble telescope for a long time to take images from every angle of the earth. The Hubble telescope its traveling around the earth this very moment. After taking soo many images they put them together, and by observing similar galaxies. Even though our planet is part of the Milky Way, we are located at a far end of one of the two smaller arms out of a total of six. As if you were looking at your whole body, exept your head cause you just cant. but you have and idea what it looks like by looking at other peoples heads. Also they are trying to get a telescope to the moon so that the images are more clear, cause there is no contamination or gases in the moon's atmosphere. To measure the distance to a galaxy, they try to find stars in that galaxy whose light out put can be measured. then determine how far away the galaxy is by observing the brightness of its stars. Using that method, astronomers can measure the distance to galaxies 300 million light years away. and if a galaxy is too far way to distinguish individual stars, astronomers use supernovae in the same manner, because the light output of supernovae at their peak brightness is a known fact. Supernovae ts been used to measure the distance to galaxies as far as 10 billion light years away. How about that? amazing, isnt it?

Our galaxy cannot be seen in its entirety at the present time. Simple reason: we're within its boundaries, and unable to travel to a location outside them to gain the proper perspective. Observations of galactic structures from within can reveal its general characteristics, and in fact, the Milky Way is now thought to be a barred spiral galaxy, rather than a spiral as was originally thought.

We are inside our galaxy, the Milky Way. So it surrounds us in all directions. The wide-angle view toward the Galactic Center does look a bit like an edge-on view of other galaxies, however.

Since were embedded in our galaxy we can't see it from the outside but every star youu see at night is from our galaxy. There are a few other close by galaxies that we can see with our eyes but we can only see the stars in our own.

There are no images of our galaxy, only images of others that they say ours looks like.

With the Hubble Telescope, visit their website and they will explain it in detail. There are many observatories around the world they use and they all have high powered telescopes. You can visit one in your area, it is very interesting.

we are inside our galazy, the milk way. perhaps we are in the centre. so what we see are only are only different points of the galaxy. furthermore, nowdays we can use a telescope to see.....................
