A study reported on August 24, 2026, by MIT describes records of ancient magnetism in calcium-aluminum-rich inclusions (CAIs) from the meteorite DOM 08006, discovered in Antarctica's Dominion Range in 2008. The grains formed during the solar system's first 200,000 years, according to the researchers, making them the oldest known solar-system material. The work suggested a magnetic field existed during the solar nebula stage.

The team estimated a field of about 150 to 600 microteslas, roughly three to 12 times Earth's magnetic current field. The researchers proposed that such a field could have helped move gas inward toward the forming sun alongside gravity. The findings appeared in the Proceedings of the National Academy of Sciences. NASA supported the research in part.
