An article published in a recent scientific journal Nature Physics, reveals details of a scientific experiment in which scientists using laser beams in controlled laboratory conditions to recreate the process of a supernova explosion. The experiment carried out by researchers from Oxford University astrophysicists will examine in more detail and to understand such a cosmic event. On the pages of a scientific journal, scientists report that a supernova explosion is one of the most amazing documented cosmic events in the Universe , accompanied by an incredibly powerful release of energy. They occur because the core fading stars are no longer able to maintain the fusion reaction, and then explodes, creating an incredibly powerful shockwave. Scientists from the University of Oxford and colleagues explain that despite the fact that in general these events (the appearance of supernovae) occur on the same scenario, sometimes they still differ from each other, resulting in a very strange form of supernovae. Hoping to solve this mystery, scientific experts decided to use laser beams to try to recreate such a cosmic event in the laboratory and watch his process. As a result, scientists have found that the interstellar matter, formed as a result of supernovae are not always distributed evenly on outer space. In the experiment, the scientists focused on three laser beam aim, the role played by a carbon rod with a thick tuft of hair. When lasers heated carbon rod up to 1 million degrees Celsius, it exploded. Given that the rod was placed in a chamber filled with rarefied gas , and was on the polymer network, which simulates the seal gas clouds that occur in space, as a result of the explosion turned heterogeneous. "This experiment demonstrated that the explosion energy passes through the grid and becomes unstable and turbulent, as in the case of Cassiopeia A ( a supernova in the constellation Cassiopeia)," - says Professor Gianluca Gregori. " Our observations may also refute the notion that a supernova explosion propagates inside the interstellar matter is homogeneous. In fact, this is not always the case. And this was confirmed in the framework of our experiment and mathematical models of shock waves that pass through a sealed outer space", VIDEO:
