Space: Horizon: Jupiter Revealed, 9pm, BBC2

Thanks to Nasa’s Juno mission, scientists are starting to scratch the surface of Jupiter to reveal the wonders that lie within. Tonight, Professor Kaitlin Kratter reveals how extreme the planet is, with the aid of a quarry and a few rocks, giving some idea of the size of the largest body in the solar system. Jupiter is on another scale entirely when it comes to mass. On Kratter’s scale Mercury is a single kilogram and the Earth is 17, but Jupiter is 7 tonnes. And at the National Ignition Facility in Northern California, Dr Marius Millot uses powerful lasers for an experiment giving an idea of the pressures inside Jupiter. Toby Jones narrates.
