The Moon was Pummeled by Asteroids at the Same Time the Dinosaurs Died. - Coincidence? by spacewriter
Glass beads collected by the Chang’e 5 mission date back some 66 million years and could have formed from impacts. Courtesy Beijing SHRIMP Center, Institute of Geology, CAGSThe team looked at the idea that large impacts, such as the Chixculub event, were accompanied by smaller impacts. The event that led to Chixculub’s formation happened about 66 million years ago. If the “big one” aimed at Chixculub had company, then it’s a good idea to look at the Moon, too.
The death of the dinosaurs is one of the most fascinating stories to spring from Earth’s ancient geological history. The story goes that an impact was certainly part of the story. Some 65 million years ago, Earth was basking in the Cretaceous period. Dinosaurs had been roaming the planet for about 165 million years. They still reigned across the globe along with some of the earliest mammals and other forms of life. However, the number of dinosaur species was starting to shrink.
Co-author Associate Professor Katarina Miljkovic, also from Curtin’s SSTC, said future comparative studies of the lunar samples could also add to our store of knowledge about the Moon’s geological history. “The next step would be to compare the data gleaned from these Chang’e-5 samples with other lunar soils and crater ages to be able to uncover other significant Moon-wide impact events which might, in turn, reveal new evidence about what impacts may have affected life on Earth,” she said.
So, the death of the dinosaurs and the mysterious glass beads are likely related. They both speak to a larger bombardment event that involved both Earth and the Moon.
