Astronomer and cosmic optician Dr. Simon Dye joins us in the studio to talk about about cosmic lenses - the magnified images of distant galaxies that we wouldn't normally be able to study. Simon studies these rare distant objects and attempts to work out what they look like. By doing this, Simon can study how galaxies formed and evolved in detail not available in unmagnified systems.
To begin our journey into cosmic lenses, we must remind ourselves about that ubiquitous force that is responsible for many a dropped phone - gravity. You can listen to our previous show all about gravity below, or skip to the next paragraph for the condensed version especially for those on the go.
