Magnetic Field In Meteorite Provides Clues About Formation of Solar System
An anonymous reader writes Scientists have discovered a meteorite that provides evidence that intense magnetic fields caused the formation of the solar system. A meteorite called Semarkona crashed in northern India in 1940 and is now being studied for signs of primordial magnetic fields. Lead researcher, Roger Fu, a planetary scientist at MIT says: "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." From the article: "This meteorite is made up of mostly tiny round pellets known as chondrules, which formed droplets that quickly cooled in space. According to the study, the scientists focused on these chondrules that possessed iron-bearing minerals, known as dusty olivine crystals, and if they appeared to have a magnetic field present while they were cooling, then the magnetic properties of these crystals might have recorded the strength of the magnetic fields."
