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....

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.

Amazing course! Definitely good for beginners. However, the course expects you to know the fundamentals of Physics, such as basic kinematics, forces, a little bit about energy and light, simple equations (solving and rewriting in Mathematical notation), etc. Anyone who has taken Highschool Physics should be able to understand the course without much difficulty.

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!

This course clearly and succinctly explains the relationship between technology and its impact on our expanding knowledge of astronomy. As an amateur astronomer who spends a lot of time imaging various objects in the night sky, this course gave me a much better understanding of the equipment and processes that I use.

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.

Professors Andy Lawrence and Catherine Heymans make it a joy to learn more about the science and technology of astronomy, especially in this current era of the James Webb Space Telescope. I highly recommend this course to anyone interested in astronomy. Thanks so much. I really appreciate it.

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!

I found the course really ingaging and enjoyable. Its a great basic guide with lots of jumping of points, deeper into each topic. The videos where fun and informative, the quizes could be a bit padantic at times but overall tested you well. I particualy enjoyed the maths questions.

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

This is one of the most amazing courses that I have taken.Even though wasnt able to attaend it due to exams and such for some time, I got back at it without much effort, I could still understand what I was taught and could try and apply what I learned.Highly recommend.

Just Awesome, The Additional Materials provided was excellent because for the freshers they get to know the best websites to view the information regarding Science.

You can pretty sure gain knowledge about the latest technology behind the Astronomical Discoveries.

This course is so good. It covers high level concepts but got me super interested in aspects of astronomy I didn't even know existed. The information is brief but really useful and gets one thinking about the broader picture. Thanks for a great course!
