The Universe Today
The Universe today is very different from the Universe of the past and of the future. However, we can discover much about the past and the future from what we can currently observe. The Universe today is filled with structure and behavior that is both beautiful and puzzling.
There is a very well organized Large Scale Structure apparent in the Universe that both excites and confuses Astrophysicists.
The Universe is also not static, in fact we live in an Expanding Universe.
Additionally, the entire Universe is permeated by The Cosmic Microwave Background Radiation which gives many clues as to the origin of the Universe.
