"How do they know that?" Modern astronomy has made some amazing discoveries: how stars burn up and how black holes form; galaxies on the edge of the universe and killer rocks right next to it; 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 technology alone 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 with a prominent scientific result. We'll 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, totaling approximately 40 minutes. They will be in a regular pattern: a brief introduction, an example science story, an explanation of the key technological area, a look at how the technology is used in practice, and finally a look at what the future may hold.
