The way Carlo Laj tells it, the 1980s were a dead time for scientists studying Earth's peculiar habit of flipping its magnetic field every few hundred thousand years. Laj and other paleomagnetists spent the decade roving the world, accumulating records of times when the magnetic field reversed...

What causes the northern lights? The northern lights give us a unique window into our sun's activity, space weather and Earth's magnetic field. At any given moment, the sun is ejecting charged particles from its corona, or upper atmosphere, creating the solar wind. When that wind slams int...
Earth's magnetic field then redirects the particles toward the north and south poles. The electrically charged particles then enter Earth's atmosphere, exciting gas atoms and molecules and generating auroras. The process is similar to how neon lights work: When the molecules and atoms get "...
Magnetic field of Earth.(Image credit: alxpin via Getty Images) Magnetic fields are generated by the motion of electric charges, according to HyperPhysics. Electrons all have a fundamental quantum mechanical property of angular momentum, known as "spin." Insideatoms, most electrons tend to form...
