1. Images of the deep universe allow us to study galaxies at many different distances
2.

regions of slightly enhanced density in the early universe.
3.
Elliptical galaxies may have formed from protogalactic clouds that were spinning
more slowly or were denser than those that formed spiral galaxies.
4.
Quasars are extremely luminous and are a very energetic and distant active
galactic nucleus.
