Earth’s Magnetic Field Origin Correlation
February 22, 2013 in Science
“The Earth’s global magnetic field is generated in its metallic core, located nearly 3,000 kilometers beneath the planet’s surface. The field has existed on Earth for at least 3.5 billion years and offers clues about how other planets, stars and celestial bodies may have formed.”
“Ganymede is the largest satellite in our solar system. It is larger than Mercury and Pluto, and three-quarters the size of Mars. If Ganymede orbited the sun instead of orbiting Jupiter, it would easily be classified as a planet.
Ganymede has three main layers. A sphere of metallic iron at the center (the core, which generates a magnetic field), a spherical shell of rock (mantle) surrounding the core, and a spherical shell of mostly ice surrounding the rock shell and the core. The ice shell on the outside is very thick, maybe 800 km (497 miles) thick. The surface is the very top of the ice shell. Though it is mostly ice, the ice shell might contain some rock mixed in. Scientists believe there must be a fair amount of rock in the ice near the surface. Ganymede’s magnetic field is embedded inside Jupiter’s massive magnetosphere.”
Around 3.5 billion years ago proto-earth #2 Europa transitioned to become proto-earth #3 Ganymede, which is the only known satellite that currently maintains a strong magnetic field.
