Episode description

A star in the nearby Pinwheel Galaxy has exploded spectacularly into a supernova, dubbed SN 2023ixf. It is the brightest in a decade and it has got astronomers around the world into a frenzy. Science in Action hears from both amateur and professional astronomers alike as they scramble to collect exciting new images and data.

Back on the ground, we hear from the Professor of Climate Change and Earth System Science at the University of Exeter, Tim Lenton about his new paper highlighting how rising global temperatures could push human populations from their homes.
