In Our Time: 25 Explorations of Space: A BBC Radio 4 Collection

Melvyn Bragg and guests discuss the cosmos, from the origins of the universe to dark matter and dark energy

'Consistently superb' John Banville

In Our Time is a linchpin of the Radio 4 schedule, attracting over 2 million listeners a week since its launch in 1998. Erudite, edifying and enlightening, it tackles serious ideas succinctly, providing fascinating insight into subjects ranging from the Fibonacci Sequence to Frida Kahlo.

In this special thematic anthology, we traverse the solar system, the galaxies and the multiverse, voyaging across space to explore 25 celestial objects and phenomena. Included are programmes on the universe, the sun, the moon, the stars and the planets - among them our near neighbours, Venus and Mars. Also featured are discussions on comets, asteroids and black holes, as well as eclipses, exoplanets and the mysterious, invisible substance known as 'dark matter'. Topping and tailing the collection are episodes dealing with the science of astronomy, examining Ptolemy's geocentric theory of the universe and the relationship between astronomy and the British Empire.

Hosted by veteran broadcaster Melvyn Bragg, with contributions from expert scholars and academics including Sir Martin Rees, John Gribbin, Carolin Crawford and Sir Roger Penrose, these captivating colloquies will inspire anyone with a sense of wonder and a thirst for knowledge.
