This is a 3-D radiation magneto-hydrodynamic FLASH simulation of the experiment, performed on the Mira supercomputer at Argonne National Laboratory. The values demonstrate strong amplification of the seed magnetic fields by turbulent dynamo. Credit: Petros Tzeferacos/University of Chicago

Laser experiments verify ‘turbulent dynamo’ theory of how cosmic magnetic fields are created. By creating a hot turbulent plasma the size of a penny, that lasts a few billionths of a second, the researchers recorded how the turbulent motions can amplify a weak magnetic field to the strengths of those observed in our sun, distant stars, and galaxies...
