Studying a supernova explosion allows astronomers andphysicists get information about the processes occurring during the formation of galaxies and reveal many secrets of the universe. However, the observation of the moment of the explosion, during which an ultra-powerful shock wave is formed, capable of accelerating matter to a speed close to the speed of light, is carried out at very large distances, making it difficult to study the physics of the process in detail. Therefore, scientists from the United States tried to simulate a supernova explosion "in vitro" in order to study in detail shock waves in a laboratory.
The process of a supernova explosion occurs inthe result of a contactless impact of ions and free electrons in a gaseous medium or in a plasma. As a result, ions and electrons move under the influence of a powerful electromagnetic field created in a plasma. The shock wave generated by the supernova explosion generates powerful electromagnetic fields, which leads to multiple reflection of uncharged particles and their acceleration to maximum values close to the speed of light.
Particle movement should be carried out withfast enough to overcome the shock wave. Scientists decided to check the theoretical research in the field of a supernova explosion in laboratory conditions.
During an experiment to produce a shock wave,simulating a supernova explosion, American scientists used a laser system from the National Laser Thermonuclear Reaction Complex (Livermore), which is one of the most powerful in the world.
During the experiments, plasma flows were directedtowards each other, which created conditions close to the events occurring during the supernova explosion. As a result, a shock wave was created similar to the wave generated by a supernova explosion, and scientists studied particles moving at a speed close to light. Testing is at an initial stage and scientists have yet to study many physical phenomena that accompany the explosion.
