Meteorite studies have shown that the magnetic field in the early Solar System was several times stronger than Earth’s magnetic field today. Purdue University planetary scientist Cauê Borlina said they examined iron-bearing minerals in a meteorite that fell to Earth in 2008. Simulations show that this field contributed to transporting gas to the young Sun; during the Sun’s initial formation, it swallowed more than 300 Earth masses of gas per year. More meteorites need to be examined to confirm the findings.
Why it matters
The findings show that the magnetic field is one of the key variables in models explaining the movement of gas during the formation of the young Sun. This framework could help clarify the physical conditions that made the rapid transfer of gas possible during the Sun’s early stages. The fact that the study is based on iron-bearing minerals in a meteorite shows that conditions in the early Solar System can be investigated through samples available today. However, the current result needs to be tested with a broader sample group; it remains unclear whether different meteorites carry the same magnetic signatures and to what extent the simulations will correspond with these findings.
