Magnetic Mysteries: The Birth of Metallic Asteroids
#Meteorites #PlanetaryMagnetism #AsteroidCollisions
In a groundbreaking study published in Proceedings of the National Academy of Sciences, Yale researchers Zhongtian Zhang and David Bercovici have cracked the code behind a puzzling phenomenon - the traces of a magnetic field in certain metallic meteorites. This discovery could hold the key to understanding the formation of magnetic dynamos at the cores of planets, shedding light on the internal structure and evolution of celestial bodies.
Planetary magnetism plays a crucial role in deciphering the secrets of Earth, Mercury, Jupiter's moons Ganymede and Io, and even traces of ancient magnetism on Mars and Earth's moon. However, iron meteorites have puzzled scientists with their hints of an internally-generated magnetic field, seemingly defying explanation.
Join us on this fascinating journey as we delve into the world of "rubble-pile" asteroids, collisions between asteroids that lead to the formation of metal asteroids capable of generating and recording their magnetism. Learn how these cold, iron-heavy asteroids with a warm, liquid outer layer create convection and magnetic fields, potentially lasting for millions of years, ultimately leaving their magnetic mark on iron meteorites discovered on Earth.
Be part of the cutting-edge research and explore the intriguing connections between celestial bodies and their magnetic histories. Don't miss this captivating scientific breakthrough that brings us closer to understanding the secrets of the universe.
