01.06.10: Do Primordial Magnetic Fields Roam the Cosmos?

NASA’s Fermi Gamma-ray Space Telescope may have uncovered a new high energy mystery. Like our own Earth, galaxies and even large scale galaxy clusters have magnetic fields shrouding them. The fields of mature galaxies such as our own Milky Way should have been seeded during the early formation of their weaker ancient counterparts. Perhaps these got their start from early supernovae, which spewed charged particles forth into the cosmos. These galactic magnetic fields may even help control the modern era rates of star formation, as well as regulate interstellar gas and guide cosmic rays.
