Astronomers: From Copernicus to Crisp
(Compass Point Books, Sept. 1, 2008)
In the past, some people believed Earth was the center of the universe. Others believed that the planets had magical powers. Most believed Earth was flat. Scientists called astronomers built telescopes and observatories to study outer space. Because of these early astronomers and their work, we now know more about the sun, the stars, the planets, and the galaxies. For more information, read Outer Space, another book in the Mission: Science series.
