Buried Lunar Rock Points to a Magnetic Field 4.2 Billion Years Ago
The moon has no global magnetic field today, but a buried rock formation on its far side may hold evidence that it once did. By combining measurements of gravity and magnetism from spacecraft, researchers found signs that the rock cooled in a magnetic field about 4.2 billion years ago. The study, led by researchers at […] The post Buried Lunar Rock Points to a Magnetic Field 4.2 Billion Years Ago appeared first on Knowridge Science Report.
Scientists believe they have found evidence that the Moon had a global magnetic field.
The magnetic anomaly under Dewar's whirlwind pointed to ancient moon geodynamics.
A strongly magnetized rock body on the back of the moon could be an archive of the early lunar magnetic field. The joint analysis of gravity and magnetic field data indicates that the moon had an internally generated field of more than eleven microtesla around 4.2 billion years ago. This gives new support to the theory of an early lunar dynamos. Zurich (Switzerland). The [...] The article Moon probably had a magnetic field 4.2 billion years ago …
Researchers have discovered a huge magnetized rock on the far side of the Moon, using orbital data to confirm the existence of an ancient magnetic field that is 4.2 billion years old.
