About the Course

"How do they know that?" Modern astronomy has made some astonishing discoveries - how stars burn and how black holes form; galaxies from the edge of the universe and killer rocks right next door; where the elements come from and how the expanding universe is accelerating. But how do we know all that? The truth is that astronomy would be impossible without technology, and every advance in astronomy is really an advance in technology. But the technology by itself is not enough. We have to apply it critically with a knowledge of physics to unlock the secrets of the Universe. Each week we will cover a different aspect of Astronomical technology, matching each piece of technology to a highlight science result. We will explain how the technology works, how it has allowed us to collect astronomical data, and, with some basic physics, how we interpret the data to make scientific discoveries. The class will consist of video lectures, weekly quizzes, and discussion forums. Each week there will be five videos, totalling approximately 40 minutes. They will be in a regular pattern - a short introduction, an example science story, an explanation of the key technology area, a look at how the technology is used in practice, and finally a look at what the future may hold....

After completing the course, I was able to understand better some concepts in astronomy such as dark matter and dark energy as well as the technologies that helped uncover more truths in our universe.

The course was amazing especially when the instructor was explaining by using experiment instruments above all the way the instructors has taught me has completely made me understand the concepts.

I m Bruno from argentina, i m 15. This course was very interesting, although i don t understand some of the equations that Catherine explained because I didn t learn equations with such complexity at school yet, but I was able to understand the concept that interested me.

Very good.

The course was really boring and unengaging

Great course!!! Very clear, very interesting! Just the right level of detail to be interesting to both people who know no physics and people who know a little more (high school physics). The different technologies are presented by showing how they can help us explaining a specific astronomical phenomenon. The integration is not seamless (there is some overlap / some physics points are spread across several weeks) but it's close enough. I would take another course by the same instructors without any hesitation. If you are interested in astronomy as a science (and not only as a body of knowledge) don't miss this course!

Everything was great. I really like the instructor's British accent, and the topic this course covers.

I'm majoring Computer Science, and I always desired to contribute to Astronomy. It wasn't easy as I expected(quizzes especially), but this helped me to get a rough idea of Astronomy's current research field. Completing this course will be my first step for that.

Additionally, I loved the view of The University of Edinburgh!! This course was so great and classic that I'm considering to transfer to this University.

Great thanks to both of the brilliant instructors.

This was my first Coursera learning experience. I did the course purely out of interest as I wanted to learn more about astronomy technology (having an interest in astrophotography). This was a great course to learn more about some of the techniques professional astronomers use to undertake scientific research. I really enjoyed it and learnt from it. The presenters came across as being really passionate and knowledgeable. Overall, an excellent online learning experience.

I have always been interested in learning about space and its hidden secrets. This course helped me to understand how astronomers study our Universe using big telescopes. It was a great experience learning how astronomers use the latest technologies to collect and analyze the data from the big telescopes. Also, I learned how we find the distance, size, mass, and other properties like the redshift using the data from different sensors of the distant Universe.

If you are searching for a course that can give you clear explanations and explain the functions of all the technological devices that allow scientists to pursue astrophysics fundamental research, this is absolutely the right choice for you:-) I enjoyed everything, and the quizzes after each unit was challenging enough to foster reasoning and deeper the learning path started with the lessons provided. Well done!

Fantastic course for a beginner like me with no prior knowledge about Astronomy. Gives you loads of information about different elements of the universe with good details around how technology integrates with all the different elements to help us understand the overall picture better and be able to predict and past and future of our ever expanding universe. I am very glad I took this course.

Very good teaching style. Good integration of video snippet, resources, exercise. Quiz are medium difficulty, but good. Of course this course scratch the huge topic of modern astronomy: I am pretty sure that 3 to 4 courses like this might give a more that satisfactory overview of the current astronomy challenges. I will be more that willing to pay for getting an official grade on the topic.

Congratulations to the instructors for putting together such a dynamic and informative course. Catherine and Andy are well prepared for the lessons and talk in a very clear manner - including examples and demonstrations whenever possible. I feel like now I know the answer to most of the stuff I used to ask when learning about astronomical discoveries; i.e. "how do they know that?"

I learn number of thing from this course. I got knowledge about astronomy and astrophysics. It also have explained abou detector and telescope. In this course I learn about dark matter and dark energy which is amazing concept about universe. And also It is mystery to explaine about full concept. Thank you thank you so much for this stage. I really love this course and coursera.

It's an best starting knowledge package for those who are seen the beautiful Dream for working in the field of astronomy. As this course includes very basic and essential things to perform Astronomical Discovery hunt. Thanks Coursera and the mentors Mr. Andy Lawrence and Ms. Catherine Heymans in this course for plotting the same...

If you wanna learn about science and technology for discovery astromical, this course its for you. On this six week's you will learn about science, telescopes, stars, black holes, galaxies, how we can see the most beautifulls images from the galaxies, dark energy and matter.

Join the course! Knowledge is never too much!

I recommend this course to all the budding astronomers who want to gain more knowledge in this field. The course is slow placed, which gives you plenty of time to do extra research on particular topics and the quizzes are just perfect, as it covers all the knowledge you gained in that weekly session.

The course is very informative, detailed and the presenters are funny too.

Though a physics graduate student would know basically 90% of the course, there are some misconceptions which can be cleared by this course. Being taught by experts in their fields is always fun and exciting. Thank you!

Excellent instructors, videos, teaching strategy.

I was looking for a course with this material for a long time and this one is my favorite between all of them. Congratulations to the University of Edinburgh, this course producers, instructors and all the team who made this course.

Loved this course a lot. Very interesting course and excellent teaching giving an overall idea and perspective of an astronomers real hardwork. Gained some knowledge of the technology behind astronomy and also the difficulties faced by astronomers. Looking forward to learn more.
