Andromeda, estimated to contain several billion stars, likely DOES include many massive stars in all stages of development. But unfortunately, it’s too far away. At 2.5 million light years, that is, 25 times farther than the width of our entire Milky Way galaxy, even the Hubble Space Telescope has great difficulty seeing individual stars.
