Episode description

This week, the Reykjanes volcano in Iceland has erupted, following weeks of seismic activity. Edward Wayne Marshall, from the University of Iceland, brings us the latest science about the volcano.

Also this week, the UK's 40-year-old JET fusion facility has been switched off. Roland Pease went along to watch.

Fusion facilities are trying to create clean energy by replicating the processes in the Sun. And the Sun itself is currently approaching solar maximum, which means we may get to enjoy more spectacular auroras but could also experience widespread radio blackouts. Solar physicist Dibyendu Nandi, from the Centre of Excellence in Space Sciences in Kolkata, tells us more.

And in the outer reaches of our Solar System, the iconic Voyager 1 craft has started sending back nonsense data. William Kurth, who has worked on Voyager since its launch in 1977, reveals his personal and scientific connection to the mission.
