This is a nice quick story of a solution to this mystery that did not have a satisfying answer. The answer was discovered by high school students.
quote:Yet one pattern commonly found around craters has remained a puzzle. Sometimes, these craters contain radial rays of debris fanned out around the impact zone. In the lab, scientists have tried to reproduce these patterns by dropping balls into containers of sand or beads, yet have found little success.
quote:But in a recent study published June 27 in the journal Physical Review Letters, a team of scientists has finally made some progress in understanding how crater rays form, and their inspiration comes from an unexpected source: high school students.
Science is about adding to the understanding of the nature of the Universe.
