The countdown to the solar eclipse continues. Brian Cox and Dara O Briain are joined at Jodrell Bank Observatory by legendary Apollo astronaut Buzz Aldrin, along with Dr Matt Taylor, who updates them on the European Space Agency's Rosetta mission after last year's groundbreaking touchdown on comet 67P.
Liz Bonnin reports live from the Faroe Islands as she steps up her mission to take to the skies and beam back the most spectacular images of Friday's solar eclipse. The team reveals how to view the eclipse safely and Brian ponders how the movements of our solar system mean we can predict the next eclipse to the second.
Dara investigates whether asteroid mining might be the next booming market and Dr Lucie Green has news of the very rare appearance of five planets during the daytime.
