A complete course about astronomy, history of science, scientific method, astrobiology, cosmology, etc.

I found this course very stimulating for studying, observing, searching ...

Finally some contributes (little movies, songs, sketches, interviews) are very nice and funny.

Thanks to Prof. Impey !

I wanted to learn more about Astronomy without the pressure of a credit course. This course is perfectly suited to people who want science explained in an easy to understand way. I am extremely impressed with the presentation of materials and the lectures themselves. Would highly reccommend.

This course is excellent, I have been fascinated with each week of learning. I would certainly take it a thousand times more. It is very well structured, it never gets tired and Chris Impey is one of the best presenters, his humor and his love for Astronomy make you fall in love with it too.

I am happy to have been able to study this very interesting area, which by the way is a bit close to my former profession (I am a nuclear engineer already retired). It was extremely interesting, informative, I repeated some things, but I also learned a lot of new things. Thank you very much.

Very good training. The material in teach astronomy is really interesting.

Thanks for developing this training I have really enjoyed a lot doing it.

Thanks a lot Chris for your work and giving the possibility to grow in the wonderful world of Astronomy and Astrophysics.

Considering it was an online course, I did not expect it to be as professionally organized and presented as it was. I gained such precious knowledge and a great amount of useful and interesting information. This course answered most of my questions about astronomy, satisfying my curiosity.

I enjoyed the live question and answer sessions with Professor Chris Impey. The course was comprehensive and an enjoyable introduction to astronomy. The projects were also enjoyable, especially the MicroObservatroy project. The course has inspired me to look for further astronomy courses.

i truly indebted to course era for offering such an course on Astronomy. After the completion of course i can not only under the scientific jargons of Astronomy published in articles / journals published across the world but also discuss with my fellow members on the topics of interest.

This is probably the best thing I have experienced and learned because I really am in love with Astronomy, so I enjoyed every single video and quiz. And of course, Chris Impey is the most awesome professor for this, he knows so much and I could understand clearly everything he taught me.

Clear explanations even for foreigners and lots of interesting interactive materials. The course will fit also for absolute beginners like I am. Very interesting lectures and I continue to watch online Q&A conferences with the Prof. with great pleasure! Thanks a lot! I had a lot of fun.

The course was amazing. Prof Chris Impey was brilliant and his lectures were truly great. Would surely be in touch with him through his lectures on youtube. I have a great desire to spend a week or so at Steward Observatory. I request Dr Impey to give me an opportunity to visit. Thanks

This course is a tour-de-force. It's grand in scope and covers pretty much everything I could think of. It showed me the wonders of the amazing Universe we live in. Thanks, Prof. Chris Impey. You are an amazing teacher. Highly recommended to anyone who is interested to learn Astronomy.

Excellent course. The videos were very sharp and precise. The explanations we clear. Assignments were interesting and aided quicker learning. Quizzes were interesting too. This is a very good course for anyone who wants to expand their knowledge horizon in understanding space and time.

I love the well-prepared, accessible style of the course. I also enjoyed how it progressed in building block style. I will be downloading and rewatching many episodes trying to absorb more information. I will definitely take it again next time it's around!

Thanks for all your hard work!

Es una buena actualización de diferentes temas de astronomía. Muy bueno para aficionados al tema que quieran ir un poco más de la simple divulgación y quieran mojar sus pies en el metodo científico y como este se usa para llegar a las ideas mas actuales en la astronomía y astrofísica.

É apaixonante!

Astronomia é simplesmente apaixonante, do momento que sua ficha cai até o momento que você se forma e trabalha na astronomia.

Como sonhador da astronomia, eu recomendo com todo o meu coração e sou extremamente grato por este curso!

Requere no minimo um inglês mais fluente!

It is a brilliant course that helped me to understand; it teaches you something new and expands some knowledge of the Universe. It gives you adequate assignments and questions to check your understanding and gain confidence and skills. It also helps you to gain some reviewing skills.

This is a fantastic course from start to finish, I only wish it was longer. However, we are fortunate to have more courses from Professor Impey and his great team here in Coursera, such as the Astrobiology one in which I just enrolled. Many thanks to everybody who made this possible.

This course was amazing and has a lot of informations for those who wants to study astronomy and to do something new. In these days of lock down it helped me to know about the universe and to explore my self. I would like to thanks to professor Impey for such an extraordinary course.

Thank you very much for this course!

I've learned a lot in every week!

There are so many information!

The quiz is from easy to difficult which needs to understand before answering it!

I hope many teachers/students will finish this course for their knowledge improvement about Astronomy.

Spent a worthy time throughout the duration of the course. All the explanations were concise and understandable for a novice like me aiming to explore the space in the near distant future. An awesome place to start with! The perfect launchpad for future aspiring space enthusiasts.

I enjoyed this course from the start till the end. Exploring time and space led me to explore new ways of learning about the world beyond imagination. I am surely going to look forward to many more such courses in future. Thanks for making me fall in love with physics even more.

An excellent introductory course. My only comments were that some of the slides were out of sync with the videos but that wasnt a huge problem and the Teach Astronomy book is not easy to read from an ipad. But a great 1st course for me and I will look for more. thanks Penny

My love for astronomy just got more interesting with this course. This was my first course on Coursera and I must say that Professor Chris Impey really takes this subject to a whole new level of understanding. I will definitely go for another course on Astrobiology made by him

It has been a very enjoyable and interesting course. I think prof Chris Impey has done a very good job on communicating this subject to an audience that doesn't have to come from a scientific background. I'll follow him on social media to keep track of what he has been doing.
