How Old is the Universe?
Astronomers estimate the age of the universe in two ways: by looking for the oldest stars, and by measuring the rate of expansion of the universe and extrapolating back to the Big Bang. This site explains how these measurements are made and points out the discrepancy in ages derived from the two methods. It features images, background information, and links to other resources regarding the age of the universe.
