Study finds impacts to have been up to 2.6 times higher than it was two ninety million years ago
Between 2 and 3 times as many asteroids have struck the earth and the Moon, since the age of the dinosaurs, researchers said.
The mounting pace began around 290 million years ago, and likely coincides with some kind of giant cosmic smash-up in the main asteroid belt between the orbits of Mars and Jupiter, researchers reported in Science.
The result was space debris, some of that made its way to the earth and the Moon.
These impacts send a shower of space rocks to the earth, which will probably reach a peak, and then, decay with time, said co-author Tom Gernon, professor in earth science at the University of Southampton.
The study did’t draw any direct lines between the ramp up in Asteroid strikes and major life changing events in Earth’s ancient past. a huge asteroid is largely blamed for the demise of the dinosaurs, which disappeared sixty five million years ago.
The question is whether the predicted change in asteroid impacts can be directly linked to events that occurred long ago on Earth, said co-author Rebecca ghent, an professor at the University of Toronto’s Department of Earth Sciences.
“Though the forces driving these events are complicated and may include other geological causes, asteroid impacts have surely played a role during this ongoing saga.” more research is also required to figure out, how the pace of asteroid impacts has changed over the past two ninety million years or so.
