Volcanoes Shook Moon for a Longer Time
posted in Animal Species |The moon was shook up by volcanoes for a much longer time than what the scientists had earlier thought of. The Japanese lunar satellite KAGUYA exposed the young dark “seas” of the volcanic rock, which took shape 2.5 million years old.
As of date, the existing belief was that lunar volcanism began immediately after the formation of the moon about 4.5 billion years ago and came to an end 3 billion years ago.
Scientists can identify the age of the lunar landscape by the craters that have been blasted by meteors. The more older the region, the more craters it contains.
Less craters can be found on the far side of the lunar maria or the basalt seas, which means they are young.
The findings will force the scientists to reconsider the early geological findings of the moon.
The findings appear in the November 2008 issue of journal Science.
