This great value two-in-one book reveals the high-tech worlds of space and machines as you've never seen them before. Space not only explains how to look at the night sky and how planets and stars were formed, but reveals fascinating facts about the history of space exploration. Did you know, for example, that Discovery blasted off in 2009 with a bat clinging to its external tank? Mighty Machines introduces you to everything from Robosaurus, the 12 metre-high robot that can lift, crush, burn and bite, to the extraordinary Harley Davidson motorbike that looks just like a cheeseburger. Informative, off-beat and fun, this lavishly illustrated book will appeal to even the most reluctant of readers.
