Magnetism Of Planets And Stars

Astrophysicists settle cosmic debate on magnetism of planets and stars. 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.

Good to see a long-held theory that has been taught in classrooms now has an experiment to verify its results! I was surprised that it hasn't been proven earlier.
It would be good if he could run an experiment at high pressure as well, to simulate planetary cores.
