Microscopic mineral grains in one of the earliest known meteorites reveal that a powerful magnetic field likely played a role in the formation of the solar system during the first 200,000 years of its history. The discovery suggests that about 4.6 billion years ago, not only gravity but also magnetism may have helped shape the primordial cloud of gas and dust into the young Sun and its surrounding protoplanetary disk. The results are published i…
Traces found in meteorites that are 4.5 billion years old show that strong magnetic fields, as well as gravity, played a role in the formation of the solar system.
Meteorites have preserved traces of forces that operated more than 4.5 billion years ago, in the period before the Sun was fully formed.
Before the complete formation of the Sun, tiny pieces of rock already recorded the magnetic forces present in the very first solar systems. More than 4.5 billion years later, scientists learned to read these records. Ancient rocks suggest that the cloud of gas and dust that gave rise to [...]
Before the sun formed completely, small pieces of rock already recorded the magnetic forces present in the early solar system. After more than 4.5 billion years, scientists learned how to read this recording. Ancient rocks suggest that the turbulent cloud of gas and dust that gave birth to our solar system was [...]
