Researchers create shockwaves in the lab that mimic supernovas

When stars explode into supernovas, they produce shockwaves in the plasma surrounding them. Scientists say that the shockwaves are so powerful they can act as particle accelerators that blast streams of particles, called cosmic rays, into the universe at nearly the speed of light. One of the mysteries of science is how exactly the supernovas do that. Researchers have devised … Continue reading
