  "account": "Meteorite dust grains discovered in Antarctica have revealed magnetic clues that may shed light on the birth of the Sun. Scientists from the Massachusetts Institute of Technology (MIT) analyzed calcium-aluminum-rich inclusions (CAIs) found within a meteorite called DOM 08006, which was discovered in Antarctica in 2008. These CAIs are among the oldest known materials from the early Solar System, formed during the first 200,000 years of the Sun's existence. Professor Benjamin Weiss of MIT explained that the presence of these ancient magnetic fields offers a clue to the strength of the magnetic field in the protosolar nebula, where the Sun and its planets formed. The MIT study proposes that the CAIs either retained their magnetism during early disk formation or were magnetized during later heating events within the protoplanetary disk. These early magnetic fields played a crucial role in shaping the structure of the disk and driving magnetized winds that influenced the formation of the Sun and its planets.",
  "summary": "Those little dust grains that fall to Earth during meteor showers or end up as part of larger meteorites found on Earth may hold surprising clues to the formation of the Sun. That's because they record the state of the magnetic field in the protostellar nebula from which Earth (and ultimately the planets) formed.",
