Using one of the world's most powerful laser facilities, a team of scientists experimentally confirmed a long-held theory for cosmic magnetic field generation: the turbulent dynamo. 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.https://www.sciencedaily.com/releases/2018/02/180209131436.htm
