University of Arizona
The University of Arizona is the state’s land-grant university and a member of the Association of American Universities—made up of just 62 universities in the country. As one of the world’s premier public research universities, the university conducts more than $625 million of research annually. Home to two allopathic medical schools in Tucson and Phoenix, the UA Tech Park, and a member of the Arizona Space Grant Consortium, the university creates an $8.3 billion economic impact for Arizona. U.S. News and World Report placed 14 University of Arizona graduate programs among the top 20 in the nation and it is one of the nation’s top producers of Fulbright Scholars. With its strategic academic and business plan, “Never Settle,” as its guide, the university is producing graduates who are global citizens, engaged leaders, and fulfilled individuals.
Notation et examens
An excellent course with wonderful extra sources of information and practical things to do.
A very interesting course in the aim of having broad look of astronomy with many lessons to help you to explore many interesting topics. For me it has been really worthy to take part of the course.
What an amazing class and enjoyable experience this has been for me personally. I feel that now I can at least understand some basic fundamental properties of the cosmos. I have been a follower of Dr. Carl Sagan for many years and Professor Stephen Hawking (RIP) as well. I thank my lucky stars (pun intended) for wonderful teachers like professor Chris Impey who has created a remarkable presentation of facts, theories and ideas that we know about the universe and salts our curiosity to continue exploring the big questions of who we are, where we came from, and what does it all mean. That you professor Impey for all you and so many others introduced in this class have done.
All the best,
Michael Fredericksen (Indiana, USA)

This course is a must for everyone interested in astronomy with very little to no prior knowledge. The instructor has huge experience in education and is clearly very familiar with the most common misconceptions people have. To me it was a fascinating journey from Earth, through our Solar system, to the most distant quasars. It also follows the Copernican revolution from the Heliocentric system, to Multiverse and Simulation theory.
Quizzes are not that hard, but there are some assignments to write. Some videos you might want to watch couple of times to fully understand them.
