The Moon has got two tails. One is a tail of sodium gas that streams behind the Moon as she moves. The other is a tail of dust particles. Both stretch for hundreds of thousands of kilometres in the wake of the Moon.
Gary, of course, has his own views on the tails – visit www.gks.uk.com/Ram-headed-Amun/
