the earth and the moon have been taken in front of around 800 million years ago a massive Meteor storm. Close craters of Japanese researchers from the analysis of the Moon. The total mass of the then-fallen meteorites, therefore, was 30 to 60 Times as large as that of the asteroid that wiped out 65 million years ago the dinosaurs. The Team led by Kentaro Terada of Osaka University reported in the journal "Nature Communications" about his analysis.researchers analyzed 800 million years old crater
The scientists had with the help of shots of the Japanese moon probe "Kaguya" the age of 59 impact craters more than 20 kilometres in diameter on the earth's satellite is determined. Unlike on earth, there is on the moon has almost no Erosion, the dignity of the crater with time. The moon, therefore, can serve as an archive of major meteor showers in the earth's history. The analysis showed that 8 of the 59 impact crater must be at the same time, including the Copernicus crater.
With around 40 to 50 trillion tons of Material that went out on the earth and the moon low, that they also may be hundreds of billions of tons of phosphorus fell from the sky, and the biological conditions on the earth's surface have changed, as the researchers have calculated. Phosphorus plays in numerous processes of life an important role.
Other studies have found evidence for a fundamental change in the phosphorus cycle in the Cryogenium. The Phosphorus content of recent samples had on average four times higher than in samples from the time before the Cryogenium. The Meteorite could have resulted in some of the Ecosystems have developed larger and increasingly complex forms of life, argue the scientists.
