In the early hours of Saturday morning (UK time), British astronaut Tim Peake will climb into a cramped Soyuz space capsule to begin his journey back to Earth, bidding farewell to possibly the best room with a view ever created.
During his six months months aboard the International Space Station, Peake has circled the globe more than 2800 times, taking thousands of photographs to document his mission and his unrivaled view of the most awe-inspiring light show on the planet.
His stunning pictures have revealed how the aurora - the Northern and Southern Lights - regularly illuminate the sky far above our heads as charged particles from the sun smash into the Earth's atmosphere.
There are two types of auroras - Aurora Borealis, which means 'dawn of the north', and Aurora Australis, 'dawn of the south.'
