Young Galaxy's Magnetic Field Is Surprisingly Strong
Current models indicate that the magnetic fields that enclose galaxies grow slowly over billions of years. But scientists have used a telescope to peer back millions of years in time and discovered a distant galaxy with a magnetic field at least 10 times the average strength.
Arthur M. Wolfe, professor of physics at the Center for Astrophysics & Space Sciences at the University of California-San Diego, discusses the questions raised by this startling discovery.
