The big bang theory, a graphic timeline of the universe!
“Hubble Ultra Deep Field” of Galaxies!
This view of nearly 10,000 galaxies is called the Hubble Ultra Deep Field. The snapshot includes galaxies of various ages, sizes, shapes, and colors. The smallest, reddest galaxies, about 100, may be among the most distant known, existing when the universe was just 800 million years old. The nearest galaxies–the larger, brighter, well-defined spirals and ellipticals–thrived about 1 billion years ago, when the cosmos was 13 billion years old.
