Different Generations Of Stars
It is hard to really appreciate the universe we live in. However, if you look at the stars in the night sky it can really be a beautiful thing to behold. Just imagine seeing more than just the white coloring of those stars. In the image above, you can do just that! What you’re seeing is a massive cluster of stars filled with blue and red stars. Some of the stars are large supergiants, especially some of the brighter blue stars. Yet you will also see several white stars in the middle, each of them seems brighter than the others around them.
Usually, blue supergiants are far more bright than white dwarf stars. That is actually what you’re seeing in the middle and not white stars as you might assume. It’s an easy mistake to make due to how freaking bright those stars are. Yet if you look close, they are all blue. It is amazing to think about how many stars there are. In just the Milky Way, there are over 100 billion stars! Around some of those stars, planets are present. Some of the planets are in habitable zones where life is possible. Of course, outside the Milky Way, there are quintillions of other stars with planets surrounding them.
