Plasma Physics
Researchers at CERN have generated plasma 'fireballs' to simulate jets from distant blazars, shedding light on the mystery of missing gamma rays. The experiment suggests that ancient intergalactic magnetic fields, rather than plasma instabilities, may explain the phenomenon. Published in PNAS on November 3, the findings highlight potential remnants from the early Universe.

Researchers have discovered that Earth's magnetosphere carries a reversed electric charge on its morning side, contrary to long-held assumptions. Satellite data and simulations reveal negative charges there instead of positive, with the pattern flipping near the equator. This finding, led by teams from Japanese universities, explains plasma motion's role in shaping space weather.
