Key topics include:
- How photographic images are generated from radio telescopes, despite only receiving radio waves, and the fundamental principles behind this technology.
- A deep dive into gravitational waves, their impact on space, and how LIGO detects these minute disturbances in the fabric of spacetime.
- An imaginative discussion on what sounds might exist in space and the potential smells one could encounter beyond Earth’s atmosphere, including the curious idea of cosmic fragrances.
Join Andrew and Jonty as they demystify these concepts, providing clarity and insights into the wonders of astronomy and space science.
