Today is the great Copernicus' birthday. He is the one who figured out that the Earth is not the center of the universe.
Nicolaus Copernicus: The Earth is a Planet by Dennis B. Fradin & illustrated by Cynthia von Buhler is a great picture book that tells in simple language the story of his life. I loved the illustrations which are more like oil paintings. This is great book to introduce Copernicus to anyone who wants to know more about the origins of astronomy.
