How did the infant sun form? Scientists get surprising new insights from 4.6-billion-year-old space dust

New research suggests that dust from meteorites contains a "fossil record" dating back to the formation of the sun. The research reveals that magnetism played a far greater role in the birth of the solar system than had previously been suspected.Around 4.6 billion years ago, the solar system was a cloud of gas and dust, known as a solar nebula.
