Astronomy DVD For Sale by Peter Wilcox (July 2019)
I have a brand new unopened set of the Great Courses; Understanding the Universe: An Introduction to Astronomy, 2nd Edition – 96 x 30min lectures on DVD and a course book. The lectures are given by Professor Alex Filippenko. This usually retails for £154 plus delivery I’m selling it for: £75 including delivery to a GAS meeting or I will sell it by post.

This visually rich course is designed to provide a nontechnical description of modern astronomy, including the structure and evolution of planets, stars, galaxies, and the Universe as a whole. It includes almost all of the material in my first two astronomy courses for The Teaching Company, produced in 1998 and 2003, but with a large number of new images, diagrams, and animations. The discoveries reported in the 2003 course are integrated throughout these new lectures, and more recent findings (through mid-2006) are included, as well. Much has happened in astronomy during the past few years; we will discuss the most exciting and important advances.
