Welcome to the Companion Website for Astronomy Today, Fifth Edition by Chaisson/McMillan. Built to complement the text as part of an integrated course package, this site is a useful supplemental aid to your astronomy course.
To enter the site, select a chapter from the chapter menu above.
Annotated Animations and Images, as well as Web Destinations - all regularly updated to reflect the most recent astronomical discoveries.
Practice Problems contain algorithmic versions of the end-of-chapter Problems from the text.
A Study Guide features interactive multiple-choice quizzes with hints and instant feedback.
To view the Animations, you need a QuickTime plug-in. If this is your first time at this site, or if you have switched computers, you will probably want to run the "Browser Tuneup" by clicking the button below, to check to see if you have QuickTime.
Additional materials for both instructors and students are available in our Course Management offerings for this textbook.
