Ancient Meteorite’s Magnetic Fields May Provide Clues on Planet Formation


Solar system with orbiting planets and star

Good picture showing the debris field of what used to be planet Man. Some day it will be information found in school books around the world. Until then, it's only crazy talk.

Back to the subject at hand, "clues on planet formations", according to this article. No, forget it.

According to an ET source in crazy-talk land, all planets and moons in this system and many that have passed over, leaked out of this solar system, over the billions of years this place (star system) has been chasing its tail around existence, have some Man planet in them.

That's not going to be in the school books anytime soon, especially the part about humans living on that planet. Start putting truth into school books and children might get excited about going to school. Who wouldn't love to learn about all the fantastic things going on in the universe? The billions of types of intelligent life forms and races, doing their thing while traveling inside of super spaceships, and visiting exotic star systems, whenever they want.

No, lets keep teaching our children that humans are unique in the universe, special, and the spawn of apes (and that god loves ape children). That should get our childrens' juices flowing.

btw. everything in the solar system, planets too, are made from star spittle. Put that in your school books, and smoke them.

Researchers at Arizona State University have recently performed a series of laboratory investigations into the magnetic fields within the grains of an ancient, 1.5-pound meteorite. The team now believe the meteorite, formed around 4.5 billion years ago, may prove critical to understanding how the solar system first formed.


“The measurements made by [study researchers] Fu and Weiss are astounding and unprecedented,” explained study co-author Steve Desch of Arizona State University’s School of Earth and Space Exploration. “Not only have they measured tiny magnetic fields thousands of times weaker than a compass feels, they have mapped the magnetic fields’ variation recorded by the meteorite, millimeter by millimeter,” he continued.

As the solar system started to take shape, a considerable amount of debris was formed during the construction stages. For years, scientists have been pouring through this material, in the hopes it will provide important clues relating to how the planets formed. The oldest, and least changed, remnants of this process are called chondrites. These small chunks of rock are outcasts of large asteroids that were once involved in high-impact collisions, and are made of round granules, called chondrules.
The chondrules formed in the solar nebula around the sun, at a time when they were subjected to extreme temperatures over a sustained period. Globules of molten rock are formed from passing dustballs of solar material, which then cool and solidify into chondrules. After this cooling period is over, the iron-containing minerals within the chondrules become magnetized. Today, these magnetic fields can still be detected by scientists.
The research team looked at a meteorite that was discovered during the 1940s in India. The meteorite, named Semarkona, contains olivine-bearing chondrules that are rich in iron. While the team established that these chondrules had a magnetic flux density that was similar to that of Earth, Desch and colleagues claim the chondrules became magnetized before reaching the planet’s surface.
“The new experiments probe magnetic minerals in chondrules never measured before. They also show that each chondrule is magnetized like a little bar magnet, but with ‘north’ pointing in random directions,” explained Desch.
Using a series of intricate models, Desch discovered the formation of chondrules was made possible by a series of shock waves transmitted through the solar nebula. Since the recorded magnetic field strength was 54 microtesla, the researchers believe the nebula’s “background field” was likely in the region of five to 50 microtesla.
In a recent press release, Desch stated, “This is the first really accurate and reliable measurement of the magnetic field in the gas from which our planets formed.”
The study, entitled Solar nebula magnetic fields recorded in the Semarkona meteorite, was published in the Nov. 13 issue of the journal Science.
