measured from one end to another end, how many kilometerS?
if we are also in the milky way, how can we see milky way?

The nearest such galaxy is Andromeda. It is roughly similar to the Milky Way in size and shape. Two closer galaxies, the large and small Megallanic Clouds are closer to us but smaller - and are visible to the naked eye in the southern hemisphere.Originally posted by Saint
BTW,
how may galaxies do we have that resemble milky way?
Are they bigger? What're their names?

Do you think we may have several solar systems in milky way that can also harbor living things like the earth!
I think it is possible!

You ask how we can "see" it and we cannot see it in the sense of getting an outside perspective. We can only see it from inside and IMAGINE what it would look like from outside.
if there isn't life in our galaxy i hearby declair that whatever technology they have at the time when it is eventually worked out can bring me back to life and that each and everything on the Earth can give me 10 spanks anywhere with a cricket bat!Originally posted by kyle_soule
It is quite possible! I would like to think there is life elsewhere in our galaxy.

Sorry, not quite the truth of it, the reason why we can see the milky way galaxy, is because our Sun is near the outer edges of it, in one of the spiral arms that it has.

So sorry, my references of such things I have not 'updated', as what I had remebered comes from a reference source that I had read as a kid, back in the 60's, and it told of the Sun being ~45,000 ly out in a ~100,000 ly galaxy.
Just went to a more up to date reference source, they pin it at real close to central from the center. (7 to 8 kiloparsecs)
But they do not seem to distiguish, as you did Marcus, seeing it in the summer, and winter skies, as being a different view, could you explain why?
A re-read makes your statement of inner/outer 'perception' clearer, as I had found that statement, rather unclear, I suspect it is the 'Imagine' part, as mapping it gives up a very clear 'outside' view as it is mappable as it is not a 'solid'. (closed to our view)

Scientifically, it is possible for other planets to harbor life, but you must also take other factors into consideration:
Time, planetary temperature, environmental hostility, etc..
At the time of the formation of simple life on earth, elements such as carbon, nitrogen, hydrogen, sulfur, phosphorus, etc were present, and were therefore synthesized into the daily life of these organisms over a VERY long period of time. Perhaps if elements like arsenic and mercury (along with oxygen) were present instead of our organic elements, life may have adapted around those elements instead.
Scientists use a variety of methods to determine the size of our galaxy, including studying the movements of stars and gas within the galaxy and using telescopes to observe the structure of the Milky Way. They also use mathematical models and simulations to estimate the size of the galaxy.
The current estimated size of the Milky Way is approximately 100,000 light years in diameter. However, this number is constantly being refined as new data and observations become available.
It takes approximately 100,000 years for light to travel from one end of the Milky Way to the other, due to its vast size.
The size of the Milky Way is considered to be average compared to other galaxies. Some galaxies, such as the Andromeda galaxy, are larger while others are smaller. However, the Milky Way is unique in its structure and composition.
The size of the Milky Way may change in the future due to interactions with other galaxies or the merging of smaller galaxies. However, these changes occur over millions of years and will not significantly impact our understanding of the size of the galaxy in the near future.
