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....

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.

An excellent opportunity for astrophysics enthusiast for anyone in an enginnering or an applied physics background as you get a clear understanding of various celestial objects and how modern astronomy differs from the ancient astronomy.

This course helped me build my basics about astronomy. I now know things i couldn't have learnt otherwise. Such an intriguing course. And for an amateur astronomer this is definitely the course that I would recommend. Simply loved it.

It was a great experience learning about the universe and the modern technology that we use to understand the nature of the universe and explain scientifically about the various phenomenon taking place in space.

Thank you

The maths questions struck a great balance between challenging intuition but accessible (maths skills wise) and the explanations of concepts were really clear! Enjoyed and would definitely recommend :)

Explanations are clear and insightful. The concepts discussed are far from simple, but they are exposed in a very natural way. An extended, deeper version or a follow up course would be nice!
