Hypothetical super-hurricane that could possibly form from an asteroid hitting the ocean. An extraterrestrial impact could trigger a hurricane in the normal manner, but would cause it to be much bigger because of the much bigger input of heat energy. It is not known for sure, but it is thought that Jupiterís Great Red Spot is possibly an existing example of a hypercane. The photograph below is an image of the Great Red Spot that was taken by Voyager 1 in February of 1979, 9.2 million kilometres away from the planet. The white oval below the Great Red Spot is a storm that is roughly the size of the Earth.
