The magnetic structures resulting from a plasma instability predicted by the physicist Erich Weibel about 50 years ago have been evidenced at surprisingly large scales in a laser-driven plasma in the prestigious journal Nature Physics. This instability is also expected to operate in astrophysical settings where it is held responsible for the acceleration of cosmic rays and the emission of gamma photons in the famous “gamma-ray bursts.”
