Washington (AFP) Nov 07, 2014
Last month, an exotic deep space comet flew by Mars and unleashed an unexpectedly strong meteor shower that briefly changed the chemistry of the Red Planet's upper atmosphere, NASA said Friday. The comet, Siding Spring, came from a distant region of the solar system known as the Oort Cloud. Its rare shave past Earth's neighboring planet on October 19 at a speed of 35 miles (56 kilometers) per second was closely monitored by a host of human-made spacecraft.
