Today I completed this amazing Astronomy course in 2 month. Initially I try to complete the course within 1 month but as the course going on my mind didn't ready to accept all the theories like string theory, 10th dimension, Brane, Drake, Big Bang drawback, expansion of universe at speed more than light, exoplanets like earth and many more.

During the study, headache occurr in mind, but I tried to learn all these.

Thankyou Coursera, Prof. Imphey & Christy Mam for this wonderful journey.

Even though human life scale is negligible small as compared to our universe, our intelligence is what will cover the gap. And courses like these not only inspire us to research but also motivates us that we still have a long road to achieve greatness and this might not be achieved by fighting and talking on this pale blue dot. I am very much pleased by your content Prof. Chris . Hope you keep on making such content and our search for our better selves will continue beyond.

This course is a perfect beginners guide to astronomy. It's simple enough to follow yet detailed enough to give you a real sense of the field. The video lectures and readings are interesting and well organised in week by week topics. The assignments are challenging without being too time consuming. Professor Impey holds live YouTube question and answer sessions almost monthly, giving you direct access to him.

I found this course engaging, satisfying and truly educational.

This was a brilliant course to truly know about astronomy and to know about the secrets of space. The division of course into 11 weeks and these different categories provides a detailed approach to every topic included in the course. This course covers every topic related to astronomy. The photographic PDF files provided before every week is a very good thing to provide to a student as they change the point of view of the student to looks at the aspects of Sciences.

This course was extremely interesting and informative, from the very first week till the very last. The insertion of relevant clips and images during video lectures, as well as the pace of course delivery was spot-on. The instructor is extremely knowledgeable and I learnt a lot about astronomy from the course. The difficulty was not high either, as very little prerequisite information was required in the course.

Highly recommended for all astronomy enthusiasts.

It was an excellent course for full 11 weeks. Lot of information were fed to us continuously each week. I will definitely go through various articles and videos online. With basic knowledge on various fronts of astronomy, I will be able to comprehend as well as appreciate the difficulties astronomers go through each day. I have come to know what infinite space-time is.

Thank you Chris and your videos were amazing and the presentation could not have been better.

Wonderful course and Prof. Impey was articulate in his explanation with the right level of details to explain various phenomena and principles that govern astrophysics, space and time. The online interactions were really useful in understanding several new facets on the frontiers of modern study and investigation. Thank you Prof Impey for putting together this wonderful course, it helped me understanding few concepts that I was keen to understand and learn.

El Profesor Chris Impey es un educador extraordinario, cuya metodología y didáctica hacen que cualquier alumno pueda aprender y luego aplicar lo que se enseña. Es inspirador. Se preocupa por el aprendizaje no solo desde el día 1 del curso, mantiene comunicación con alumnos a través de sus sesiones en vivo en YouTube. Actualiza sus vídeos si se requiere y ejemplifica a todo nivel las teorías que pueden resultar complejas para quienes inician en Astronomía.

"Really" learning the fundamentals of Astronomy has been something I'd wanted to do for many years but had never really made the time nor found the right level of learning material to make it happen. Professor Impey's course was incredibly digestible and truly fascinating, broken up with large doses of interspersed humor to wash it all down. Thank you University of Arizona Astronomy Department for making this subject so accessible. I'm truly grateful.

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.

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.

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.

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 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.
