The clue to the formation of the solar system could be locked in the meteorite which was formed some 4.5 billion years ago. Researchers from the Arizona State University have been carrying out a string of experiments on grains found on the primeval meteorite weighing 1.5 pounds.
Researchers associated with the MIT, Cambridge University and other universities postulated that the formation of early Solar System could have been influenced by powerful magnetic fields of magnitudes which have never been seen before.
Researchers say that experimental evidence hints that the solar system’s protoplanetary disk has been shaped by powerful magnetic field nearly 100,000 stronger than anything seen today. The intense magnetic field propelled massive amount of gas towards the Sun in a few million year. The same intense magnetic field propelled the dust grains on a collision course and eventually smashing them together and creating conditions necessary for the formation of terrestrial planets including the Earth.
The early periods when the Solar System was being formed, huge quantity of debris were produced. The most ancient of these unaltered and oldest remains of this evolution is known as chondrites. The Chondrites are fragments of huge asteroids which are involved in these collisions. The chondrites are composed of round granules known as Chondrules. These chondrules are created in a solar nebula circling the sun. After cooling, the minerals containing iron inside the chondrules are magnetized. Scientists are able to detect these magnetic fields today.
The meteorite which the research team analyzed was found in India in the 1940’s.The meteorite which was christened Semarkona contained chondrules rich in iron. The chondrules magnetic flux density was akin to Earth but researchers feel that it was magnetized before reaching Earth.
The details of the study were published in the journal Science in issue November 13.
