Paul takes time out from outreach at the Festival of Tomorrow at the Swindon STEAM museum to chat with Professor Robert Walsh of the University of Central Lancashire, who with artist Alex Rinsler has created a giant representation of the Sun as an outreach and art project that uses the data of the Solar Dynamics Observatory. They talk about solar science, the coronal heating problem, sounding rockets, space missions professor Walsh has been involved with, space weather and why he has his own Sun.
