Asteroid impacts on the moon millions of years ago coincided with some of the largest meteorite impacts on Earth, including the one that wiped out the dinosaurs.

That’s the discovery of a new study that also found that the largest impact events on our planet did not occur in isolation, but were accompanied by a series of smaller impacts.

Experts say their findings shed new light on asteroids in the inner solar system, including the likelihood of potentially devastating asteroids heading for Earth.

The team studied microscopic glass beads up to two billion years old that were found in regolith brought to Earth from the moon in December 2020 as part of the China National Space Agency’s Chang’e-5 lunar mission.

Heat and pressure from meteorite impacts created the glass beads, and scientists say their age distribution should mimic the impacts, revealing a timeline of the bombardments.

Lead author Professor Alexander Nemchin, from Curtin University, Australia, said the findings suggest the timing and frequency of asteroid impacts on the moon may have reflected back to Earth, telling us more about the history of the evolution of our own planet.

“We combined a wide range of microscopic analytical techniques, numerical modeling and geological studies to determine how and when these microscopic glass beads on the moon formed,” he added.

“We found that some of the lunar glass bead age groups precisely match the ages of some of the largest terrestrial impact craters, including the Chicxulub impact crater responsible for the dinosaur extinction event.”

The study also found that large impact events on Earth, such as the Chicxulub crater 66 million years ago, could have been accompanied by a series of smaller impacts.

The Chang'E-5 spacecraft landed in one of the youngest regions of the Moon, located at mid-high latitude, and returned 1,731 g of samples to Earth in 2020

“If this is correct, it suggests that the age and frequency distributions of impacts on the moon could provide valuable information about impacts on Earth or the inner solar system.”

Co-author Associate Professor Katarina Miljkovic, from the Curtin Space Science and Technology Center in Australia, said future studies could help shed light on the moon’s history.

“The next step would be to compare the data obtained from these samples from Chang’e-5 with other lunar soils and crater ages in order to discover other significant impact events across the moon which, in turn, could reveal new evidence about what impacts they can have. affected life on Earth,’ she added.

The findings are published in the journal Progress of science.

KILLING THE DINOSAURS: HOW A CITY-SIZED ASTEROID KILLED 75% OF ALL ANIMAL AND PLANT SPECIES

About 66 million years ago, the non-avian dinosaurs were wiped out and more than half of the world’s species were wiped out.

This mass extinction paved the way for the rise of mammals and the rise of humans.

The Chicxulub asteroid is often cited as a potential cause of the Cretaceous-Paleogene extinction event.

The asteroid crashed into a shallow sea in what is now the Gulf of Mexico.

The collision released a huge cloud of dust and soot that triggered global climate change, wiping out 75 percent of all animal and plant species.

The researchers claim that the soot needed for such a global catastrophe could only have come from a direct impact on rocks in shallow waters around Mexico, which are especially rich in hydrocarbons.

Within 10 hours of the impact, a massive tsunami swept through the Gulf Coast, experts believe.

This caused earthquakes and landslides in areas as far away as Argentina.

While investigating the event, researchers found small particles of rock and other debris that were thrown into the air when the asteroid crashed.

Called spherules, these tiny particles covered the planet in a thick layer of soot.

Experts explain that losing sunlight caused a total collapse in the aquatic system.

This is because the phytoplankton base of almost all aquatic food chains would have been removed.

It is believed that the more than 180 million years of evolution that brought the world to the Cretaceous point were destroyed in less than the lifespan of a Tyrannosaurus rex, which is about 20 to 30 years.
