How astronomy really works - an overview of the technology that astronomers use to collect and measure light from the universe, and how it is used in practice to make scientific discoveries.
"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 the interpret the data to make scientific discoveries.
The science of stars and stones. Archaeoastronomy is the “science of stars and stones”: it studies the relationships between the ancient monuments and the sky, in order to gain a better understanding of the ideas of the architects of the past and of their religious and symbolic world. The course provides the first complete, easy introduction to this fascinating discipline.
Explore the evolution of the universe, the future of astronomy & the role technology plays in new discoveries. What was the Big Bang? How do black holes work? Could there be life elsewhere in the Universe? In this subject we’ll address those topics, as well as gaining some insight into how great scientific discoveries were made, and what's involved in scientific research.
This is an introductory astronomy survey class that covers our understanding of the physical universe and its major constituents, including planetary systems, stars, galaxies, black holes, quasars, larger structures, and the universe as a whole.
Are we alone? This course introduces core concepts in astronomy, biology, and planetary science that enable the student to speculate scientifically about this profound question and invent their own solar systems.
An introduction to modern astronomy's most important questions. The four sections of the course are Planets and Life in The Universe; The Life of Stars; Galaxies and Their Environments; The History of The Universe.
This course is designed for anyone who is interested in learning more about modern astronomy. We will help you get up to date on the most recent astronomical discoveries while also providing support at an introductory level for those who have no background in science.
Explore the exciting world of modern solar systems astronomy in this credit-eligible course. In this introductory 4-credit hour lecture and laboratory course, we will explore the origins, structure, contents, and evolution of our solar system and exosolar planetary systems. We will cover the history of astronomy, properties of light, instruments, the study of the solar system and nearby stars.
Learn about alien life, how we search for it, and what this teaches us about our place in the universe. Super-Earths And Life is a course about alien life, how we search for it, and what this teaches us about our place in the universe.
