Science and Technology
Introducing the themes of the course, and a first look at the science and technology we will study.
Telescopes and StarsHow telescopes work, how we use them to make images in different colours, and how we use those measurements to understand how stars work.
Space and Black HolesHunting for black holes, and why we need to get above the atmosphere to do it.
Detectors and the First GalaxiesDetectors, how they work, and how we use them to catch the light from the very first galaxies.
Computers and Killer RocksWhy computers are crucial in astronomy, and how they are used to find rare objects.
Spectroscopy and Dark EnergyHow to break up light into its component parts, how that allows us to do astrophysics, and why we believe the Universe is full of a mysterious dark energy.
"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 i
Wonderful Course and Awesome Lectures! Thank you coursera and University of Edinburgh for this amazing course and really helped me to understand astro technology in detail :)
I loved this course. I would like an update especially when the James Webb Telescope starts to gather more data, but it was a wonderful course and I loved the professors.
The course was amazing especially when the instructor was explaining by using experiment instruments above all the way the instructors has taught me has completely made me understand the concepts.
A great experience. Very well explained. Practical things experimental set up of spectroscopy and telescope were explained very well. Both instructors are taught sincerely.
Delivers what it promises. I was surprised that presentations made no use of 21st century technologies, no animations, no visualizations, for instance, just pen and paper.
