❤ MAGNETIC HEART ❤ The moon once had a magnetic heart, which helped the moon generate a magnetic field stronger than Earths is now, researchers say. However, many mysteries remain about the magnetic field of the moon, such as what powered it and when it ended, the scientists added. The moon today does not have a global magnetic field. However, moon rocks that astronauts collected during the Apollo missions suggested the moon once had a magnetic field billions of years ago but scientists were uncertain whether the moon generated a magnetic field the same way Earth does, or if the magnetic fields seen on the moon were instead produced by outside forces. For instance, cosmic impacts on the moon could have sparked super-heated plasma that generated strong, brief magnetic fields, explaining the magnetized rocks the astronauts discovered.In the past six years or so, however, a new generation of scientific techniques and computer simulations has now made a strong case that the moon may have had a magnetic core like Earths. Magnetic fields are generated by electric currents.We think planets generate magnetic fields by moving electrically conducting fluids inside them, said study co-author Benjamin Weiss, a planetary scientist at MIT. Flowing metal in Earths core makes the heart of the planet a dynamo — a generator of electrical current — and this dynamo generates Earths magnetic field.If the moon had a dynamo that generated a magnetic field, that could yield key insights into its hidden inner structure.The defining question of lunar science for more than four decades, even before the Apollo missions, is to what extent is the moon an unmelted primordial body like many asteroids, as opposed to a melted evolved body with a multilayered structure, which can have a metallic core with a magnetic field, Weiss told SpaceThe moon is intermediate between a planet and a small body like an asteroid, so establishing whether the moon had an ancient dynamo could help show that it was a highly evolved body differentiated into layers like Earth, he added. #NASA #Space #Moon #Lunar #Magnetic #MagneticHeart #Cosmos #Universe #Astronomy #5Ela #GW2022 #LOVE #SHINEON Theres something magnetic about it.... It draws me to its light every night!!! Back to my grind.... the5elementz/
