The Cosmos

An exciting introduction to astronomy, the fourth edition of this book uses recent discoveries and stunning photography to inspire non-science majors about the Universe. Written by two highly experienced and engaging instructors, each chapter has been fully updated, with more than 200 new images throughout, including recent images from space missions and the world's best observatories. The newly redesigned text is organized as a series of stories, each presenting the history of the field, the observations made and how they fit within the process of science, our current understanding and what future observations are planned. Math is provided in boxes and easily read around, making the book suitable for courses taking either mathematical or qualitative approaches. New discussion questions encourage students to think widely about astronomy and the role science plays in our everyday lives and podcasts for each chapter aid studying and comprehension. 'An excellent introduction to the subject, both comprehensive and up to date. The authors convey a clear and enthusiastic pedagogic presentation of an exciting field. As a textbook, it will be of great benefit to students, providing a valuable starting point to learn about the subject. Its presentation and style will hold the reader's attention, at the level appropriate for an introductory course. It is my preferred text of this type, as it stands out for its continued excellence over time.'
