Mysteries of Space: Sets 1 - 2 (Library Binding)

Space has long fascinated humanity. Myths and legends describing what the stars are made of, the cause of an eclipse, and where the moon came from have been told for centuries. With scientific progress came the opportunity to find the truth behind these stories. Today, we know more about UFOs, asteroids, and stars than we have at any point in the past. Astonishingly, we have better maps of Mars than we do of Earth's ocean floor. Through informative graphic organizers and engaging fact boxes, readers explore what we know about space--and what we have yet to learn.
