It has been believed since long past by scientists that the strong magnetic fields must have been the root cause of the formation of the solar system. There was however no physical evidence to prove the same. A meteorite proves the same, with evidence say researchers. After the sun was formed, around 4.6 billion years ago, there was a rotating disk around it, which was formed.
This disk was formed out of dust and gases. These dusts and gases have now in the years evolved into planets, thus resulting in the very formation of the solar system. Researchers have stated that around young distant stars, such protoplanetary disks generally form quickly, around 5 million years or less.
“Magnetic fields can introduce viscosity into the disk, essentially making the gas in it more sticky. It’s a very primitive meteorite, which means that since it formed about 4.5 billion years ago, not much has happened to it. This means it preserves the properties it had when it first formed, helping shed light on that time,” says Roger Fu, planetary scientist at MIT at Cambridge, Massachusetts.
He also stated that magnetic fields actually can introduce viscosity in disks, which make them much more stickier. The gas which is found on the orbits, must have had really strong interactions with each other. And that’s how most of the gas has been falling on the star. “This is the first direct information we have on the magnetic fields in the early solar system. It’s a really difficult measurement that was very cleanly performed — it stands out as a real tour de force,” he explains.
This discovery highly indicates that the magnetic fields have been very important in the formation of the planetary system. And it has been the most important as it played a major role in causing the accretion process, due to which the solar system was formed.
