This documentary explains the workings of the sun, the body at the centre of the solar system, with a core heat of 30 million degrees. Savage Sun reveals the most spectacular images of the sun ever gathered, captured from many spacecraft and observatories. Internal temperatures can reach millions of degrees Celsius and surface explosions leap tens of thousands of kilometers into space. It is the most awe inspiring and fearsome body in our solar system, yet, without it, life on earth could not exist.
