What characteristics do Andromeda galaxy stars have?

Answer 1

Basically, the same characteristics that the stars in the Milky Way - our own galaxy - have. Aside from the fact that Andromeda is somewhat bigger, the two galaxies are thought by astronomers to be very much alike. When Edwin Hubble studied the Andromeda Galaxy in the early 20th century, he was able to discern within it several "Cephid variable" stars, which proved, among other things, that Andreomeda was a galaxy, like ours. Prior to that time, it was believed that the Milky Way was the only galaxy - the others were "clouds".

Answer 2

Stars in the Andromeda galaxy are similar to stars in our Milky Way galaxy, with a variety of sizes, ages, and compositions. They can range from small, cool, red dwarf stars to massive, hot, blue giant stars. These stars play a crucial role in the formation of galaxies and the evolution of the universe.
