Magnetism May Have Played Key Role in Solar System Formation
Confirmed
In Short: Scientists have found evidence that magnetism played a crucial role in the formation of our solar system, according to a study published in the Proceedings of the National Academy of Sciences.

Scientists have found evidence that magnetism played a crucial role in the formation of our solar system, according to a study published in the Proceedings of the National Academy of Sciences.
Meteorites, which date back to the time before the sun formed, contain records of the magnetic forces that were present in the early solar system.
The study indicates that a powerful magnetic field was present in the turbulent cloud of gas and dust that eventually gave rise to our solar system.
This magnetic field may have helped feed the growing sun, suggesting that gravity alone was not responsible for the formation of our solar system or other planetary systems.
Previous research has indicated the presence of a solar system-wide magnetic field after the sun's formation.
The findings could have implications for understanding the formation of other planetary systems in the Milky Way and beyond.
Researchers are also exploring a recently proposed form of magnetism called altermagnetism, which could potentially lead to more efficient computer memory.
By analyzing patterns in materials like ruthenium dioxide, scientists can determine whether a material exhibits magnetic properties and what kind of magnetism it displays.

What's still developing
- Meteorites hold a record of the forces at work 4.5 billion years ago before the sun formed Clouds of gas and dust, like the one in this Hubble Space Telescope image, are the birthplaces of planetary systems.
- Livio and the Hubble 20th Anniversary Before the sun fully formed, tiny bits of rock were already recording the magnetic forces present in the very early solar system.
- "Ruthenium dioxide was one of the first materials to be proposed as an altermagnetic candidate, but studies on its bulk form didn't return evidence of magnetism," said Yi, an associate professor of physics and astronomy.
- "After analyzing our measurements, including informing our interpretation with theoretical calculations, we found that, in our experimental conditions, the ruthenium dioxide shows spin textures consistent with unconventional magnetism," said Yichen Zhang, the first author on the paper and a recent Rice graduate.
- In ultrathin magnetic materials, tiny whirlpools of magnetism known as skyrmions can arrange themselves into orderly, crystal-like patterns, and those patterns may hold clues to a new generation of computing.
