歷史回顧:飛向土星(視頻)
On November 12th, 1980, Voyager Flew Near Saturn.
November 12th, 1980, more than 3 years after its launching, Voyager I edges within 78,000 miles of Saturn, the second largest planet in the solar system. Ultraviolet and infrared cameras beam pictures 950 million miles back to Pasadena, California, where scientists are stunned. The high resolution time-lapse photos confound all known laws of physics. Saturn has not 4, but hundreds of rings, dark then light, then dark again, flashing and perpetual transformation with each advance of the spacecraft. The rings appear to dance, buckle and interlock in manners never thought possible. One expert describes them as concentric circles within a cosmic pond.
