註釋The Sun is merely one of some 200 billion stars that make up the Milky Way--and the Milky Way is only one of a billion galaxies in the known universe. Packed with fascinating facts and stunning photography, this book examines the Galaxy humans call home and travels light years away, to the domain of phenomena such as the Oort cloud.
