Default When we look at the stars with just our eyes...

When we look at the stars , are all the stars we see from the Milky
Way Galaxy ? Or do we see stars from other galaxy's ?


s With naked eye, not only are the stars you see in the night sky all
s in our own galaxy, but all are in our immediate galactic
s neighborhood, which is pretty sparsely populated.

Not entirely. There are a number of stars that one can see that are
more than 1000 light years away, for instance, Deneb, Alnilan, and
Wezen are among the 50 brightest stars in the sky.

s Some bright, massive stars can be resolved in the outer spiral arms
s of the Andromeda (...) galaxy, with large earthbound telescopes
s and photographic exposures.

s But no star other than the Sun is any more than a point, even in
s the largest telescopes....they're just too distant for more.

No, the stellar disk of a number of stars have been resolved. The
most notable is Betelgeuse, as it was first resolved by Michelson in
1920.
