My first and best course for now! I am very happy to touch this topic, thank you very much!

i wanna yo ser Terry Matilsky for this massive cours .it's very useful.thak you

Good course. Great data given to work on. Excellent instructor.

Enjoyed this class and learned more than I hoped for.

Use of DS9 tool to explain the science is spot on !

Any chance of "Analyzing the Universe II" ?

Loved this course didn't want it to end.

One of the best online courses I know!

Awesome with ds9 tutorial.

very good course

best

nice

The content is interesting, and I enjoy doing the homework and exploring galactic objects with DS9. However, I would think this course is more difficult than other beginner astrophysics course that I have completed in coursera/Edx, due to the fact that some concepts were not fully explained in the video. A.K.A. it requires some background knowledge of basic astrophysics principles. Luckily I did, so I was able to pass all the tests. Might be quite difficult for a true beginner. Another tip is to play the videos in 1.25-1.5x speed, as Professor speaks slowly (but clearly). The "reading" time of the wiki sections is also much longer than other courses, which requires some effort of concentration. The course might benefit from converting some reading materials to videos so that students can understand and concentrate better. Overall, it has been an intriguing and fun 6 weeks!

Overall I was satisfied with this course. It though me some fundamental ways to use the data to calculate and identify the size and distance of stars/galaxies which I enjoyed very much, but I had a few issues too. some parts of this course were not explained in detail enough and other parts I thought it spent too much time on. I also had issues with DS9 especially using DS9 to answer questions in the test is very time consuming and few functions did not work (I got Failed!) on my computer, I was unable to provide the proper answer on those few questions. That was frustrating.

This professor is an interesting character. Course uses software that, while I was able to download it, froze on my computer.

Great Course for first steps in analyzing the universe

Good intro to DS9

As a computer science student interested in astronomy/astrophysics, not once in the entire duration of the course did I feel why am I learning this. 10/10 recommended even if you have 0 interest in astronomy/astrophysics. Prof Terry has done an impeccable job structuring the course so that you don't feel threatened by the math involved. The course is not only very informative, but also very inquisitive, entertaining and tugs on the existential questions about our universe.

Thank you, Dr Matilsky, for a fabulous course. I just loved the use of DS9 to analyze real instrument data from Chandra. The amount of math required was great. I probably could've handled even more math since I have a BS in physics but that's fine. I also like the quizzes because they helped me apply and test the learnings from the video and reading. I hope you develop another course because I'll be first in line to take it. Wishing you good health. All the best -- Sridhar

An excellent review of some basic astronomy concepts, stellar evolution and X-ray astronomy. The discussions of X-ray astronomy are significantly enhanced using the ds9 software to analyze Chandra X-ray imagery. Professor Matilsky is very interesting and entertaining. He put together an excellent course that provides a challenging and rewarding experience that you will look forward to each day as you progress through course materials.

The best coursera MOOC I have completed so far. Introduction to ds9 was a treat and really feels like a very valuable asset to go ahead with astronomy. Prof. Terry's antiques and enthusiasm for the subject made me come back to the course much more frequently than was required. Very grateful for this course.

This is for those who loves Astronomy and wanna go deeper into the subject, this course particularly revolves around X-ray astronomy and analyzing the universe in x-ray frequency using a wonderful tool called DS9 which carry the observations of NASA's chandra X-ray observatory.

I just loved the way Terry Sir taught each and every concept from basics to a practical level. I hope to learn more from you sir. Thank you so much. This course has increased my interest even more in exploring astronomical objects and phenomena.

Exceptionally excellent course.

Prof. Matilsky has put forward the taste of the astronomical world from the very basics that even a beginner like me can start from scrapes. Would love to learn through other courses from Prof Matilsky.

Learned a lot from an entertaining and energetic lecturer -- and a facinating look at DS9 image analysis. Quizes are tough, and often provide a workout on material not really covered by the lectures alone. -- keeps you on your toes.
