A study recently published in the Scientific magazine reveals that both our planet and the Moon are currently receiving almost three times as many asteroid impacts as 290 million years ago.
This result contradicts the theory that as the solar system ages and becomes heavier, the number of asteroids and comets that collide with the planets that inhabit it decreases.
To arrive at this conclusion, the investigating scientists examined the Moon's surface using the Lunar Reconnaissance Orbiter data of the NASA.
Comparing the craters of the Moon with a chronology of the craters of our planet, the researchers also found that the Earth and the Moon have experienced similar stories of impact on asteroids.
The Moon is not subject to the same forces, but it does, according to the researchers, at the same bombing of asteroids and comets.
Therefore, when analyzing the craters it was a surprise: there are more young and old holes, which means that both the satellite and our planet have received more impacts in the last 300 million years.
"Our study provides evidence of a dramatic change, produced towards the end of the paleozoic era, in the number of asteroid impacts on Earth and the moon," said the lead researcher, Sara Mazrouei, quoted from Science every day.
The theory also includes the idea that one of the collisions in the asteroid belt could cause the asteroid that led to the mass extinction of the dinosaurs. Although, for the moment, this is still only a hypothesis that researchers raise in this study.
