Discovery: History From Astronomy
A thumbnail history from the ancients of Babylon and China to the Egyptians who created today`s calendar and the Greek, Eratosthenes, who worked out that the earth is round. In the 16th Century Copernicus reasoned that the planets orbit the sun and, early the following century, Galileo first used a telescope on the sky. Isaac Newton improved it and described the effects of gravity. Last century, Edwin Hubble revealed an ever-expanding Universe-into which today we peer ever deeper.
