Astronomical concepts can be truly hard to comprehend, especially those of planetary sizes and distances from Earth and from each other. These concepts are made more comprehensible by the group of ill. in this book, which put, in scale, side by side extraterrestrial objects with objects on Earth we can more easily relate to. For example, study the pictures of Earth floating above Jupiter's Great Red Spot and the asteroid Itokawa resting beside Toronto's CN Tower. These mind-bending images bring things better into perspective and will help you understand the size and scale of our Solar System. In later chapters, you will be told how close the visionaries of the past came to guessing what today's explorers would find. Astronomer/painter Lucien Rudaux's masterpieces of Mars dust storms anticipated Viking and Mars rover images by nearly a century. Space artist Ludek Pesek envisioned astronauts setting up camp on the lunar surface in scenes hauntingly similar to photos taken by Apollo astronauts decades later. But the real benefit of this work is in better grasping the nature of our universe -- how big it is, now large it is, and how we fit into it.
