Evidence of dinosaur-killing asteroid impact found on the moon

Researchers studying tiny glass beads in lunar soil samples brought back by China’s Chang’e-5 mission have reconstructed a timeline of asteroid strikes on the Moon — and found that they mirrored impacts on Earth. The finding suggests that asteroid strikes on our planet, including the one that killed the dinosaurs some 66 million years ago, were accompanied by a series of smaller collisions both here and on the Moon. This should make the history of Earth’s bombardment in some ways easier to study: the glass beads, formed by the heat and pressure generated during an asteroid strike, are common on the Moon but harder to find on Earth.
