Cosmology is the field of study that brings together the natural sciences, particularly astronomy and physics, in a joint effort to understand the physical universe as a unified whole. Visit the sites below for more information.

Remote Sensing Tutorial: Cosmology
How did the universe begin or did it even have a beginning? How will the universe end? What evidence have scientists gathered to help answer these questions? We will be looking at two cosmological theories, the Steady State Theory and the Big Bang Theory.
ACTIVITIES on Two Cosmological Theories

 Steady State vs Big Bang
In this research activity you will be comparing these two cosmological theories, looking at evidence for and against each, and evaluating the validity of references.

As you do your research, keep track of the websites you visit. Include the title of the webpage, the URL, who wrote or sponsered the webpage and your evaluation of the reliability of the source. Number your sources so that you can footnote your research.
List the major components and points of each theory. Don't forget footnotes to show the source of your information.
Include both evidence for and against each theory. Again - don't forget footnotes.
From your research, write several paragraphs explaining which theory you think is more valid. Back up your position with specific points from your research and use footnotes.
ACTIVITIES on the Big Bang Theory
 The Expanding Universe
In this activity, you will use Hubble Space Telescope Images to view how objects in the universe change and create scientific models of the universe.
The Big Bang Theory is consistent with a number of important observations which we will be investigating: a connection between radial velocity and distance of galaxies, the observed abundances of helium, deuterium and lithium, and the thermal spectrum of the cosmic microwave background radiation
