Ancient asteroid impact creates two large canyons on the Moon's far side

New research reveals that an ancient asteroid impact created two large canyons on the Moon's far side about 3.8 billion years ago. This event occurred quickly, forming canyons comparable to Arizona's Grand Canyon in just 10 minutes. Scientists used data from NASA's Lunar Reconnaissance Orbiter to study the impact. The asteroid, estimated to be 15 miles wide, generated energy far exceeding that of current nuclear weapons. The findings are significant for NASA's plans to explore the Moon's south pole, where older rocks remain undisturbed. These rocks could provide insights into the Moon's and Earth's origins.
