Scientists use lasers to create miniature supernova shock waves on Earth

Researchers have created a miniature version of supernova shock waves in a lab here on Earth to solve a long-standing cosmic mystery.

When stars die and explode in supernovas, they create shock waves that emanate across the surrounding plasma. These powerful shock waves blast out cosmic rays, or highly energetic particles, out into the universe. The waves act almost like particle accelerators, pushing these particles out so fast that they approach the speed of light. However, scientists have yet to fully understand exactly how and why the shock waves accelerate these particles.
