Hunting for magnetic energy in intergalactic space, researchers have found an unexpected motherlode of it. Both in the gaps between galaxies that are clustered and in the lonelier neighborhoods outside those clusters, magnetic fields are remarkably strong, a scientific team reports.
As their hunt widens, the scientists find that they are detecting more extensive fields, says Philipp P. Kronberg of the University of Toronto, leader of the decades-long search. Kronberg reported the results April 29 at an American Physical Society meeting in Long Beach, Calif.
