Green, the most common colour associated with aurorae, is produced by oxygen atoms and molecules energised by the impact of solar particles that have escaped the sun’s atmosphere, causing them to glow brightly

Wanted: smart, fit and unflappable applicants for humanity’s first mission to Mars. Must have: crazy wig, oversized boots and a big red nose.It is enough to make Neil Armstrong spin in his grave, but researchers have found that the success of a future mission to the red planet may depend on the ship having a class clown.
