ScienceAncient meteorite analysis points to a strong early solar system magnetic field
An analysis of mineral grains from one of the oldest meteorites indicates a strong magnetic field existed within the solar system’s first 200,000 years.
TLDR
The meteorite analysis suggests magnetism played a larger role in early planet formation. A strong early field could help explain how dust and particles behaved in the disk where planets formed—potentially challenging existing models of how planets came together.
