Arizona's Meteor Crater is still revealing new secrets 50,000 years later - Space

Arizona's Meteor Crater, formed about 50,000 years ago, continues to yield new scientific insights as researchers study its preserved geology, impact processes, and meteoritic material. Ongoing investigations refine models of how impacts form craters, redistribute debris, and preserve or alter extraterrestrial grains, improving interpretations of samples recovered on Earth. The crater also functions as a natural laboratory that complements deliberate impact tests and helps validate approaches used in planetary defense research.
