Meteorite Minerals Reveal Unexpected Collisions in the Early Solar System

In the very early solar system, newly formed massive planets like Jupiter and Saturn stirred up trouble in their cosmic neighborhood, causing smaller bodies to collide with each other, new research shows. In the disk of material surrounding the very newly formed sun — a swirling cloud of dense gas and dust that eventually gave birth to Earth and the other planets — rocky bodies from the inner solar system experienced violent collisions with icy bodies from the outer solar system, acc
