Billions of Years Ago, Magnetic Moon Has More Powerful Than Earth

Astronomy Science ~ Moon once had a magnetic core that helped produce a magnetic field is stronger than the Earth today, according to the researchers.

They believe that the dynamo in the liquid, the core rotating moon, may have generated a strong magnetic field for at least 1 billion years. However, researchers are still puzzled by how it is produced, and when it ends.

"We think the planets produce magnetic fields to transfer power from the liquid in it," says Benjamin Weiss, a planetary scientist at MIT. Metal flow in the Earth's core to make the heart of this planet as a dynamo / generator of electric current - which in generates a magnetic field of the earth.

Planetary dynamo is generated by the induction process, where energy is volatile, the liquid turns into a magnetic field. For example the movement of Earth's liquid core, which is supported by the planetary cooling fluid moving the buoyancy of the liquid in the vicinity. "Similar to what happens in a lava lamp," said Wiess.

"We recently argued studies of magnetic Apollo samples that moon also produce a dynamo in a molten metal core." Our data show that, despite the size of the Moon is small - just 1 percent of the mass of Earth - dynamo magnetic field is very surprising (much stronger than Earth's magnetic these days) and long-lived, at least the last 4.2 billion years ago to 3.56 billion years ago. Moon currently has no global magnetic field.

However, the moon rocks were brought astronauts during the Apollo missions suggest that the moon once had a magnetic field billions of years ago. But scientists are not sure whether the moon generates Earth's magnetic field in the same way is not, or if the magnetic field seen in moons instead produced by an outside force.

Weiss and former MIT student Sonia Tikoo Review, believes "Dinamo convective core is supported by crystallization of potentially maintaining the magnetic field moon over billions of years." he said.
