  "account": "New research indicates that the protoplanetary disc surrounding our Sun likely experienced a magnetic field stronger than the one on Earth today. Study of calcium-aluminium-rich inclusions in a carbonaceous chondrite meteorite called 667 g Dominion Range 08006 suggests that magnetism may be a dominant factor in planet formation. The meteorite, discovered in Antarctica in 2008, contains minerals with extremely high melting points that are inclined to condense early. Previous researchers have confirmed the meteorite's age using isotopic dating. The researchers studied the thermoremanent magnetization of iron-nickel grains within the inclusions, concluding that they were exposed to magnetic fields of 150-600 µT when they cooled through the Curie temperature. This is significantly stronger than Earth's current magnetic field of around 30-60 µT. The findings provide the first definitive paleomagnetic signal from a carbonaceous chondrite and suggest that magnetism should be considered in simulations of planet formation.",
