The Sky at Night team listens to the sounds of the cosmos. Maggie Aderin-Pocock and Chris Lintott explore how sound can reveal extraordinary secrets about the universe - from orchestral tunes rippling on the surface of the sun and the crackle of Jupiter's atmosphere to the sound waves that reveal how the universe was formed. This is astronomy as you've never heard it before.

The universe is filled with spectacular objects, from gloriously-coloured nebulae to the swirling motion of a billion stars formed into a single galaxy. One force has created it all - gravity. The Sky at Night team steps away from the bright lights and travels to the Brecon Beacons AstroCamp to see how gravity shapes the universe, in all its spectacular glory.

Maggie Aderin-Pocock asks why so much of the night sky is filled with spheres and why not all these spheres are what they seem. Chris Lintott finds out about the newest moon in the solar system that has just formed in Saturn's rings, and how it could shed light on how the planets formed billions of years ago.

Plus, how to get great images of the night sky without using a telescope and what the shape of a galaxy tells you about its past.
