These galaxies therefore likely existed when the universe was only a few percent of its present age, and may well be members of the first class of galaxies. Some large modern galaxies make a colorful foreground to the distant galaxies. Each "dot" is a galaxy; our humble Milky has over a hundred billion stars. Yes, we are, "dust in the wind." |
