Why we can only see clouds not clear stars in the Milky way as we can see the stars which are beyond Milkyway?

Actually, all the stars you see in the sky, with the exception of a few galaxies, are in the Milky Way, in our immediate neighbourhood. We can't see any stars ';beyond the Milky Way.'; What we see, looking outward, is first objects in our own Solar System (Sun, Moon, planets, comets), then the stars (which are all part of the Milky Way), then the clouds of stars in the Milky Way, which are simply too far away for our eyes to resolve into stars. Then, much farther away, we see other galaxies, such as the Magellanic Clouds and Andromeda. The only things we see beyond the clouds of stars in the Milky Way are other galaxies.Why we can only see clouds not clear stars in the Milky way as we can see the stars which are beyond Milkyway?
To the naked eye they may appear to be a cloud, but the telescopes astronomers use have no trouble seeing stars in the Milky Way part of the sky.Why we can only see clouds not clear stars in the Milky way as we can see the stars which are beyond Milkyway?
We can see plenty of stars that are in the Milky Way galaxy. We cannot see stars clearly that are beyond the Milky Way galaxy. Yes, clouds of gas and dust do block our views of some of the Milky Way galaxy stars, but we can see through those clouds by using other instruments that can detect of electromagnetic radiation outside of the range of visible light.
hey fakeer





i'm bit confused with the word 'beyond' in your question.





We sit right in the middle of a spiral arm in our Milky Way galaxy.





The stars standing very closer to us in our spiral arm appear as clear stars. You can imagine we see before us our own spiral arm turning inwards (you look then towards the constellation Scutum), and behind us our own spiral arm turning outwards (you look then towards the constellation Puppis).





Since you can look in 4 directions through the small thickness of our spiral arm, the milky way appear on the night sky as a small cloudy stroke the whole sky around.








So the stars standing much farther in our spiral arm (and they are with many!) appear rather as that smooth cloud for the naked eye. In telescopes it reveals a splendid sight of many starlights!








We can not see the other spiral arms since dark dust clouds in the galaxy block our view. This also means the center of our galaxy is not visible. Only the spiral arm lying inner than our arm, is just visible on our night sky near the constellation of Sagittarius (so of course this is also then the direction to galaxy's center).
All the stars we see in the sky is from the Milky Way.


Maybe, you tried to look at the sky when it was raining. lol!





edit:


3 Thumbs down? Why?


Do you see the individual stars from Andromeda Galaxy?
The clouds of light that are the Milky Way look like clouds of light because there are so many stars so close together.





The individual stars we see are gerenally closer than the star clouds of the Milky Way.
