"The Great Red Spot has been a constant feature of the turbulent weather system on Jupiter for many centuries. The GRS has been getting smaller for a number of years and this summer the 'shrinking' gained momentum. Close inspection of the above enlarged image reveals 'rivers' of dark material 'leaking' from the  edge of the GRS into the surrounding belts and zones. The affect mimics an 'unravelling' at the interface between the 'Spot' and it's surroundings. Will the GRS continue to shrink? Will the the GRS disappear altogether? If so will another similar storm grow to replace it in size, colour and longevity? We can only guess, watch and wonder but how sad will it be if this old friend departs from the Jovian atmosphere, it's like never to be seen again?" - Kurt Thrust acting CEO and current Director of the Jodrell Plank Observatory.
