A 'shocking' discovery: tiny magnetic fields in meteorites reveal clues on origin...


Researchers have come across some new revelations in how the early solar system evolved with the help of tiny magnetic fields found in bits and pieces of an ancient meteorite that crashed in India in 1940.

Scientists studied magnetic fields inside the primitive meteorite chunks, which provided evidence of "shock waves" that traveled from the early sun through the dusty gas cloud of the early solar system that was key to its formation, according to Astronomy Magazine.

The solar system's formation was a messy process 4.5 billion years ago that left lots of rocky material that act as a time capsule for the solar system.

Chondrites are an ancient type of meteorite that scientists see as the best way to study the early solar system, since they are basically unaltered from the very beginning. They are pieces of asteroids that broke off after collisions over billions of years. They are made up of grains called chondrules, which are often only a millimeter in diameter. A chondrule is formed from the solar nebula heating the rock beyond its melting points for hours up to days at a time, which cooled and crystallized into chondrules.
