Who has not gazed with wonder at the night sky? The great canopy of stars stretching overhead suggests that our world is part of a vastly larger cosmos. But how large is it? Where do we fit in? And how did it all begin?
These questions have puzzled stargazers for thousands of years, and the search for answers helped spark the great advances of the Scientific Revolution in the 16th and 17th centuries. But only in our own time has the full picture of the true immensity, variety, and surpassing strangeness of the Universe come into focus.
Explore Everything There Is in 96 Lectures
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.
These lectures fully update Professor Alex Filippenko's 1998 edition of this course and his companion course from 2003. All of the material in this course is integrated so that one topic builds on another as you develop the conceptual tools that allow you to explore the Universe. For example, the study of the Solar System leads naturally to the investigation of planets around other stars and the possibility of life elsewhere in the cosmos. Likewise, rainbows and similar atmospheric phenomena introduce the subject of light, and light is the key to unraveling the mysteries of stars and galaxies.
Dr. Filippenko uses thousands of diagrams and photographs. There are almost 300 short movies and computer animations that make astronomical phenomena easier to understand, and they put planets, stars, and galaxies into context as you zoom through the cosmos. A showman in the classroom, Dr. Filippenko delights in simple, easily reproducible demonstrations that use tennis balls, apples, paper plates, and other objects to explain scientific concepts. Furthermore, he has a gift for analogies: At one point, he makes the energy content of one erg vivid by comparing it to one fly doing one push-up!
Altogether, this course is an unrivaled opportunity to experience a full-year introductory college course on astronomy, delivered by a five-time winner of "Best Professor" on campus at the University of California, Berkeley, who himself is a leading participant in some of the groundbreaking discoveries at the forefront of the field. Dr. Filippenko is both a world-class teacher and researcher: In 2006 he was named one of four national Professors of the Year by The Carnegie Foundation for the Advancement of Teaching, and in 1998 his international team of astronomers was credited with the top "science breakthrough of the year" for their amazing discovery that the expansion of the Universe is speeding up—a finding that is now shaking the foundations of physics.
