The world of optical, radio, and space telescopes will be on view for students in this fascinating story. From the first telescopes of Galileo and Newton to today’s giant twin Keck telescopes in Hawaii, readers will learn about the workings of lenses and mirrors. The book also looks at how a primary mirror is made, why the dish of a radio telescope needs to be wide, and how the Hubble Space Telescope gives astronomers sharper images than do telescopes on Earth.
