ASTRONOMY TODAY

With' Astronomy Today', Sixth Edition, trusted authors Eric Chaisson and Steve McMillan communicate their excitement about astronomy and awaken students to the universe around them. Thoroughly updated, the revised edition focuses on the process of scientific discovery and scientific method, making ''how we know what we know'' a more integral part of the text with attention to clearly and concisely presenting scientific terms to the non-science student. In addition, the authors have taken great care to identify places where they could clarify or simplify an explanation, better define a term, and discuss the process used in making a discovery. This editionoffers the most complete and innovative learning package available for one- or two-semester introductory courses in astronomy.
