Do you ever ask yourself if there are mice living in museums on other planets? Out there…in the Universe? Have you ever wondered if life exists beyond our wonderful planet Earth? And if it does… how on earth do we know? Join Waterhouse the Mouse on a whistle-stop tour of the Solar System as he searches for signs of life on the surface of Mars, and on asteroids and meteoroids hurtling through space. He inspects the robotic rovers designed to explore alien worlds and peers through powerful telescopes, which reveal the astonishing scale of the Universe. Above all he learns about the four crucial ingredients for life which make our planet such a unique place in the Solar System (as far as we know). David Mackintosh’s distinctive illustrations make this the perfect book for all children who are curious about space, aliens and the origins of life on Earth.
