Rebel Star: The Sun's Greatest Mysteries

Colin Stuart

The Sun is many things: beauty, beacon, battery, belligerent. It’s the biggest thing for light-years around and yet we actually know relatively little about it.

That’s changing thanks to an armada of new spacecraft recently lofted into the solar system to scrutinise the Sun in unprecedented detail. In a talk packed full of jaw-dropping images and videos, I’ll be your guide on a journey deep into the heart of our nearest star.

It’s the perfect way to reinforce many aspects of the physics curriculum.
