According to the HST data, very distant (and early) galaxies tend to be smaller, bluer, and more irregular than modern ones. This is because these galaxies are less evolved and have not had as much time for the formation of larger, more regular structures. The blue color also indicates that the galaxies are actively forming new stars. According to the HST data, very distant (and early) galaxies tend to be smaller, bluer, and more irregular than modern ones. This is due to the fact that these galaxies formed earlier in the universe's history when there were fewer heavy elements to form stars and the process of galaxy formation was still ongoing. As a result, these early galaxies tend to be less organized and less massive than modern galaxies.
