According to http://www.nasa.gov/mission....de.html
our galaxy will collide with andromeda sometime after 3-4 billion years. chek out the images! I wonder if SE will ever be able to simulate this collision in "say" version X rolleyes
The night sky will be amazing in 3-4 billion years!! If we could only stay alive biggrin

Alas, humanity will almost certainly be extinct in billions of years, and Earth will be uninhabitable long before then. However, much sooner than that we will probably have the capability to simulate these things so well that it will seem like reality, like in the Matrix. So you may live to "see" this after all smile

hehe.. I agree ! cool link.
What about the earliest skys of earth, they also had to be beautiful smile
Is that the sky Which saw the first men was very different of our?

maybe not

Even if humanity survives, it would be nearly impossible for evolution, whether biological or technological, to not have a profound effect on humanity in that enormous span of time. So even if something descended from humanity were to exist in billions of years, it would not be anything very much like us smile

But the odds of us surviving in any way for that long of a time are astronomically remote

Well, humanity as in Homo sapiens will certainly be extinct in billions of years; even in millions of years. But it's possible of course that our descendants, who would long since have become so different from modern humans they'll be no Homo sapiens any more, would still be alive. Maybe we'll even be a class III Kardeshev civilisation by that time and populate the entire Milky Way. surprised

I think most of the stars would be in different positions, and different stars would be visible... But there wouldn't be any changes as massive as galaxies (other than the Milky Way) being huge in the skies. The Moon would be just a bit bigger in the sky, though, because of tidal effects slowly making Earth rotate slower and the Moon go farther away.

I wonder what is the situation with the closest to milky way galaxies: the magellanic clouds and the sagitarious dwarf galaxy. Are they in some kind of ''örbit" around the milky way?

I think I heard the Sagittarius is actually being destroyed by the Milky Way's gravity; presumably it was caught and now it's getting absorbed by the bigger galaxy. I think the Magelhanic Clouds are in orbit, though.

Sag DEG is orbiting and being destroyed by the Milky Way; there is now a long stream of stars that were stripped from it looping around and through our galaxy. The Magellanic clouds are also in orbit but at a greater distance; they do not pass into our galaxy's disc. They are however being disrupted by tidal interactions with our galaxy and with each other, hence their irregular appearance. They were probably both spiral galaxies before being affected by the Milky Way's gravity; this is most evident with the LMC. Also it is good to note that the Large Magellanic Cloud is the 4th largest galaxy in the Local Group, behind Andromeda, the Milky Way, and Triangulum.
