An excellent course delivered by Prof. Chris Impey, a passionate and engaging educator, through Coursera. Easy to work through week by week. Excellent material supplied, videos, online textbook, podcasts and youtube Q&A sessions. I enjoyed and learnt so much I have enrolled on the Astrobiology course offered by Prof. Chris Impey too! On a sidenote, it really helped me having something to focus on through the last lockdown over the colder months.

This course is very interesting and very informative! It is perfect for all people who would like to know more about the astronomy, but don't know where to start. This is a whole bunch of information all in all, but Chris Impey manages to teach so, that you don't feel overwhelmed, but only interested and hungry for more! There are also from time to time the opportunities to ask questions live. I highly recommend this course, it helped me a lot!

I am in LOVE with this course. No, seriously. I can't stop talking about it. With EVERYONE I MEET. I have a degree in Chemistry, and teach Earth Science and Chemistry to high school students, so my knowledge about science for this course is up to par, but I like that it adds a LITTLE more info, and it's going to give me a chance to bring stuff back to my students. The text book is amazing, and the videos are on point. Thanks for a great class!

I haven't known absolutely nothing about this exciting theme, before I started this course, now I know everything, I've even changed my point of the world view. The material is on a high level, well prepeared and provided, every second is valuable. Thanks a lot, professor and the greatest astronomer, for your time and power that you gave to create this course, and for giving us this possibility to open a new amazing world of our universe!

A great course to get started on learning astronomy, at our comfortable pace, at the comfort of our own private space and most importantly, this course is well structured and very interesting for all age groups. Wonderful Course. Learnt a lot of essential, non-technical astronomy. Enough to ignite curiosity to take up formal studies in the subject. Now I'm a second year Physics Master's student. Loving the head start this course gave me.

I really loved this course. This was the course I was longing to pursue since chidhood. It gave me the answers to almost all of my questions. It provided me great insights to the UNIVERSE. Moreover the instructor Chris Impey has done a superb job in providing us with valuable information. The assignments, quizzes, lectures, and other resources were very informative and special. Thanks to all men behind this course for doing their best.

Dr. Impey is skilled at covering a very broad range of topics and sciences that are all a part of "astronomy". The slides were clear. The transcripts helped to reinforce the information, although probably done with vocalization software as there are many sentence fragments, homonyms for the actual word, etc. I did not see a date done but I would guess this course was constructed in 2013-2014, so the information is certainly current.

Professor Chris Impey is one of the best instructors I have come across in many of these courses. He is clear with his information, is very knowledgeable, and has a sense of humour. The mentors are very helpful too. Subject matter is exactly what is expected. A perfect course for the basic astronomer wanting to learn the basics of Astronomy. Including history, how to observe, and what is new. Love this course, would highly recommend.

Amazing course! Chris Impey is a wonderful teacher. The lectures are captivating, but at a level that is appropriate for astronomy beginners. The quizzes are only easy if you were paying attention, and the writing assignments consolidate the material. This course has made me even more interested in the subject and since starting it I have even gone beyond the scope of this course and done my own investigations. Definitely recommended.

An enormous travel experience for several weeks. Only objection is that some of the material is a little "old". Not exactly outdated, but updates are really of importance in this fast moving area. There were some updates/add-on's here and there, though. Perhaps some links etc. for self study would be possible to get in place?

But, these are no critical objections - all in all more than worth while the spent time! Next course, please!!

It's a great course to do. It gives a new perpective to look at the world around you and especially the cosmos and the universe. After taking this course, it will give you new eyes and enthusiasm to look at the open sky. Along with that it also gives you an overview of the human history and earth's history and universe history. It was very exciting and interesting to go through the videos and the assignments. Had fun and learned lot.

This introductory level course in astronomy was exactly what I was looking for. It was a wonderful survey course touching on every subject that I was interested in. Having said that, the suggested times for completing each part of a week's course work were silly. I spent hours reading the textbook and watching the videos, and I was happy to do it. I was seeking knowledge and understanding, not a quick way to get a certificate.

This course is must for one's who are really interested in Astronomy and space science. It's a whole package which starts from the history of science to Black Holes till Drake equation and ends with a question are we in a simulation. Including videos and songs related to the topic is so good and holds me to the video. I thank Dr. Chrish Impey, who have inspired me through his delivery of details and by his level of knowledge.

This course is phenomenal. I was so sad when I submitted my last quiz. One of the best online courses. Love the online textbook (wish it would work more often). Prof. Impey is a brilliant human and he just explains everything so perfectly. I wish this course was longer. I had a great time learning and the material was so easy to follow and nicely explained. Thank you Prof. Impey, you taught me the cosmos and changed my mind.

I personally from my point of view, think that the course needs to be upgraded with the latest discoveries and theories. Additional information needs to be added to make the recent discoveries more interesting. And technically, the 11-week course would be quite short to learn and extrapolate knowledge in astronomy and astrobiology. Rest all its an incredible course and I am acknowledged with great information and motivation.

Super course! i ve always loved what is above me...even if i understood very little of it...The course gave me many insights and the basics to understand it a little more...i reckon i have now a "knowledge" of 0.00000000000000000000000000001% of what is out there... i d like to get to an higher level (lets say trying to increase that factor by another decimal...so i m in the hunt for a similar course. Thanks again!

I liked this course very much and I like to thank Professor Chris Impey And mentor Christy Read for teaching me and clearing my doubts. Thank you Professor Chris Impey and Christy read.Through this course I can get introduced to Microobservatory and Galaxy zoo. Also I know about the Teach astronomy material from this course.And I would like to thank coursera for giving all these nice courses. Thank you all.

I really appreciate the effort and enthusiasm of everyone who has participated to create this awesome and really helpful course. Thank you very much. I recommend this course to everybody who is interested in space and especially the deep space and cosmos. I especially had much fun on dark matter and dark energy topics. I always wanted to take a course like that and thanks to the Arizona University, I have taken it.

an amazing course, starting from the history of the astronomy, leading towards the future of our existence, full of interesting notions about the universe.

It's the perfect course for who does know nothing or very poor about astronomy and it doesn't require math or physics or biology knowledge in advance.

I really enjoyed this journey with professor Chris Impey and it really engaged me with the astronomy.

Many thanks!

I fell in love with cosmology a few years ago and I am attending high-level conferences on the subject. However, I soon realized that I was lacking the bases of astronomy and that acquiring them would certainly alleviate my sufferings. The objective has been perfectly met, with this very comprehensive course. Prof Impey shows an excellent sense of pedagogy, which is not so obvious in the community of scientists.

In my opinion, This course is really useful for the people that have an extreme interest with astronomy and also the curious people want to exlore the masive universe. And i'm one of these people. In addition, I'm really happy when i found out this website while i was surfing my newfeed, Thank to this program, it's really lightful for a lot of questions always be held in my mind but know i have lighted up a lot.

This course is long but very well planned and executed by Prof. Impey and his team. It is an excellent introductary college level class. Attending the live seminars from the Prof. Impey helps to broaden my knowledge of astronomy, and when I read about the James Webb telescope and the obsevations from it over the next ten-twenty years, I will understand the material much better because I completed this course.

For those looking for an introduction to astronomy, this is a fun and fantastic course. Covering a wide range of material from planets and star life/death up through astrobiology and evolution, Professor Impey does an excellent job making this course fun and introducing complex topics in a manner that is easy to understand. A really great and worthwhile course...very happy to have completed it and thank you!

This course has allowed me to enter the study of astronomy and space, opening a new universe for me.

The quality of content, materials, videos, examples and resources have made it very easy to understand something really complex.

I want to congratulate and thank Chris Impey and his entire team for their work, helping to spread this valuable knowledge.

Thank you very much.

Muchas gracias.

I started this course with all the motivation to update my (very rusty) knowledge in astronomy but I was also a bit afraid that I wouldn't be able to understand some difficult concepts. I'm glad that my fears were unfounded. The concepts and explanations are clear and easy to understad, and the side materials are a great way to get additional information about the topics explored in the course.
