摘要

In The popular imagination (and also, it must be said, in the overheated imaginations of many scientists), the words "Mars" and "water" appearing in the same sentence lead inexorably to the presence of a third word: "life". So, no matter that the water in question is frozen, and that the evidence for its existence is indirect, this week's much-trailed announcement that there may be ice under the surface of Mars has got a lot of people in a tizzy. The reader could be forgiven for just a shade of cynicism. Ice is not unusual in the solar system. Europa, one of the moons of Jupiter, is entirely covered with the stuff. Indeed, work published last week suggests that its icy shell is about 20km thick-far deeper than the Antarctic ice-cap on earth. Nor has there been, for many years, any doubt that there is ice on Mars. Its own polar caps were first observed in 1666. Their discovery, together with that of their seasonal waxing and waning (confirmed by modern observations), and a network of apparently artificial channels to distribute the meltwaters (observed in the late 19th century, but subsequently shown to be imaginary), led to the idea that Mars was populated by an advanced but dying civilisation. That, in turn, led H.G. Wells to write "The War of the Worlds", firmly implanting the image of sinister extra-terrestrials in the popular imagination.

Wells撰写了《世界大战》，将邪恶的外星人形象牢牢地植入了大众的想象中。
