Skywatching: Seeing and Understanding Cosmic Wonders

Rated 5 out of 5 by from Answers to many lifelong questions I’ve wondered about the extra bands of colors below a double rainbow or the halo around my head’s shadow on a cloud bank below me. Now I know what causes these phenomenon, thanks to the professor’s clear explanations. I totally resonate with every “Cool!” and “Wow!” he exclaims. His enthusiasm is positively contagious.

Rated 5 out of 5 by from One of the best the Great Courses offers Even as a lifelong amateur astronomer, I find this course to be one of those I will view many times again and have sent several copies to my family. Great, enthusiastic presentation and video material presented by a skilled and knowledgeable lecturer. The material is current and the subject matter extensive and well explained. One of my favorites of the seventeen Great Courses I enjoy daily. A super investment for all ages.

Rated 5 out of 5 by from Torn between 4 & 5 Stars Alex Filippenko is an excellent presenter and he knows his stuff. This is a nice little follow-on to his very excellent "Understanding the Universe: An Introduction to Astronomy". I wish there was time in the lectures for a bit more detail on some of the topics but it is very easy to follow.

Rated 5 out of 5 by from An appeal to an otherwise scientific subject. Simplistic approach to the subject inspires an introductory investment in an amateur telescope.

Rated 5 out of 5 by from 5 reasons I rated this 5 stars SUMMARY: a delightful, charming & interesting course. I was surprised. Though recorded around 2012, the subject matter is still timeless. 1 Not just a basic astronomy course. I've listened to most ALL of the TGC courses on astronomy subjects - including many courses in my 70 years of study. Yes, some of the fundamentals are reviewed but sky watching includes quite a bit MORE than just astronomy. 2 For those who think they are so wonderful, wise & important - they just might discover how UN-observant they might have been. 3 Superb photos, visual aids & excellently-prepared diagrams - which are about HALF the course video. 4 No annoying, endless & meaningless hand gestures - as in my previous TGC astronomy course. There I had to use my hand to cover my iPad to block the incessant BILL-YUNS of nonsense hand gestures which is the audio equivalent of the boring "UHHH" after every sentence. Alternatively in this course, professor Alex uses spontaneous & meaningful hand gestures to make a point or illustrate a concept. 5 The good professor ACTUALLY has a refreshing personality! How unique! Likely he's WHOLE-brained since most scientific lecturers have sawdust in their lower-right brain (the typical Star Trek BORG lecturer). Wow - if professors were like this, I'd go back to college.

Rated 5 out of 5 by from Great Instructor! I purchased this Great Course because I have a passion for astronomy and I recognized the name of the professor Alex Filipenko. I was not disappointed. Professor Filipenko was professional, well spoken and did not make the course boring. In fact, it was humorous at times. Very informative. Highly recommend!

Rated 4 out of 5 by from The sky is a wonderful canvas! This course seems to be a bit different than the other science type classes I have taken from TGC. It reminded me more of a guide to take better pictures of things up above us, although his focus, of course, was more on sky watching than taking pictures. I don’t know if this it the kind of course you would find in a university, but it was interesting at any rate. The professor is clearly enthusiastic and knowledgeable about this topic. He does come off looking goofy quite a bit of the time, and there are times where I wished he would be less redundant and much more quicker to get through a topic. But he does provide quite a bit of information that will make your observation of everything from clouds to distant stars more engaging. He gets into some scientific details along the way, but the most interesting information for me were the tips on where and when to find things in the sky, and what you can do to make your viewing experience more enjoyable. Overall, I am glad I purchased this course.

About Alex Filippenko

Dr. Alex Filippenko is Professor of Astronomy and the Richard and Rhoda Goldman Distinguished Professor in the Physical Sciences at the University of California, Berkeley. He earned his B.A. in Physics from the University of California, Santa Barbara, and his Ph.D. in Astronomy from the California Institute of Technology. Dr. Filippenko's research accomplishments, documented in more than 500 scientific publications and 600 abstracts and astronomical circulars, are among the most highly cited in the world. Science magazine credited two international teams of astronomers (on which he was the only coauthor contributing to both teams) with the top "Science Breakthrough of 1998" for research on exploding stars (supernovae), which shows that the universe is expanding at an accelerating rate, propelled by mysterious "dark energy." Professor Filippenko received a share of the 2007 Gruber Cosmology Prize for this discovery, work that went on to receive the 2011 Nobel Prize in Physics. Professor Filippenko also leads the world's most successful robotic search for exploding stars. Dr. Filippenko was elected in 2009 to the National Academy of Sciences, one of the highest honors accorded to a U.S. scientist. He has also been recognized with several major awards, including the 2010 Richard H. Emmons Award for excellence in the teaching of college-level introductory astronomy for non-science majors from the Astronomical Society of the Pacific, the 2007 Richtmyer Memorial Award of the American Association of Physics Teachers, the 1997 Robert M. Petrie Prize of the Canadian Astronomical Society, and the 1992 Newton Lacy Pierce Prize of the American Astronomical Society. He was a Guggenheim Fellow in 2001 and a Phi Beta Kappa Visiting Scholar in 2002. In 2006, he was honored nationally as the "Outstanding Doctoral and Research Universities Professor of the Year" by the Carnegie Foundation for the Advancement of Teaching and the Council for Advancement and Support of Education. At UC Berkeley, Dr. Filippenko's teaching awards include the Donald S. Noyce Prize for Excellence in Undergraduate Teaching in the Physical Sciences and the Distinguished Teaching Award. He was also voted the Best Professor on Campus nine times in student polls.\r\n\r\nDr. Filippenko is coauthor of The Cosmos: Astronomy in the New Millennium, now in its 4th edition (2013), and winner of the 2001 Texty Excellence Award for best new textbook in the physical sciences. He has played a prominent role in numerous television documentaries, including about 40 episodes spanning six seasons of The Universe on The History Channel.
