An Introduction to The Earth Life System

Understanding the Universe: An Introduction to Astronomy, 2nd Edition is a nontechnical description of where that picture stands today. In 96 richly illustrated half-hour lectures, you survey the main concepts, methods, and discoveries in astronomy—in depth—from the constellations drawn by the ancients, to the latest reports from planetary probes in our Solar System, to the most recent images offered by telescopes probing the farthest frontiers of space and time.

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.

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.
