1:35 Studying Billy Apple's soiled tissues from 1974

New Zealand artist, Billy Apple's exhibition, Body Activities, opened at London's Serpentine Gallery in 1974, and caused so much controversy, authorities were ordered to take it down. The work was made of tissues covered in the artist's own bodily fluids and excretment.

Billy Apple dismantled the exhibition and carefully stored the samples. And now, they are being used for scientific discovery. Dr Justin O'Sullivan is from the Auckland University-based, Liggins Institute joins us to explain why academics are so fascinated by this usual piece of history.

Everyone and everything  that has ever lived owes its existence to the Sun. It's the star of our solar system,  controlling the weather and so much more. But  the Sun remains a mystery in so many ways says Professor Lucie Green, a solar physicist and host of The Sky at Night BBC series. 

Her first book, 15 Million Degrees: A Journey to the Centre of the Sun, sheds light on what we know about this important feature in our daily lives and what we might learn from the first Solar Orbiter mission to the Sun.
