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....

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!

course content was great. You have covered most of the topics I was expecting. But I was also expecting some more detailed learning of each of the topic. I would like if you make one more course which much more detailed study and some mathematics. Thanks for making this course

Too good!Andy and Catherine don't just explain us things they make us feel like we are actually doing them especially the detector technology and spectroscopy part.I would surely recommend this course to one who is an astrophile + a tech enthusiast.

It gave me a more deep notion about how some of the most important space discoveries have been done and I'm truly amazed by their beautiful complexity and ingenuity, it also let me with the feeling that there is still so much more to understand.
