How Neutron Star Mergers Give Birth to the Universe’s Strongest Magnets

What happens when two neutron stars collide without forming a black hole?

Japanese supercomputer simulations reveal how intense turbulence can amplify magnetic fields more than 300-fold in just one millisecond, potentially creating magnetars—some of the most magnetic objects in the universe. These findings offer new clues to the violent origins of these extraordinary stellar remnants.
