土卫六上的海:卡西尼终于证实了关于土卫六(泰坦)上存在甲烷海或者乙烷海的传闻。去年7月,飞船的雷达在它的北极附近发现了许多疑似的湖泊。新图象表明许多湖泊——最大的有10万平房公里——和地球上的海一般大。

SEAS ON TITAN: The Cassini spacecraft has finally turned up evidence of liquid methane or ethane seas on the Saturnian moon of Titan. Last July the craft's radar instrument spotted dozens of possible lakes near the moon's north pole. New images show that a few of those lakes—the largest of which is 100,000 square kilometers—are as big as some Earthly seas.
