The stars we see in our own galaxy are too close for them to be greatly different than what we see, except for the massive red giant stars that are on the verge of becoming supernovae. Betelgeuse in Orion may ALREADY have gone supernova, but we won't know for another 1500 years. Now, the Hubble Space Telescope is studying Cepheid variable stars in galaxies 10's of millions of light years away. In 10 million years, such stars can change a LOT and very likely some of the ones they have measured no longer exist and have become white dwarf stars already. We also see very distant supernovae in galaxies 100s of millions of light years away. These individual stars have already exploded, and by now have been black holes or neutron stars for millions of years.
