Professor Jay M. Pasachoff's textbook Astronomy: From the Earth to the Universe, published by Saunders College Publishing, has always provided up-to-date information on astronomy. Now, thanks to Pasachoff On-Line, you can receive monthly updates on the text and happenings in astronomy. Every month check the
What's New page to find the latest updates, or review the updates by chapter. Then move on to our expanding Astronomy WWW Index. We also provide information on ordering and ancilliaries and Professor Pasachoff's RedShift CD-ROM guide. A new and improved index for the accompanying laserdisk is also available, as are references for the use of blind students. This book teaches Critical Thinking in addition to a body of standard and contemporary material, and a set of critical-thinking questions for students to ponder is provided.
