![]() "Although this doesn't get to that directly, this research gives us a greater understanding of the physical chemistry of everything that occurred at the time the Earth formed. "In a broad sense, people have been trying forever to understand how we got here," Oulton said. Oulton presented the preliminary results of the paper at the 2015 Lunar & Planetary Science Conference and received the Dwornik Award of the Geological Society of America for the best undergraduate presentation. ![]() The research will be published in an upcoming issue of Geochimica et Cosmochimica Acta, but is currently available online. It’s the only the second meteorite fall from Florida and the only one that has ever been available, and it’s one of only six Florida meteorites Alan Rubin has published a paper showing this is a scientifically important meteorite Also, it’s one of only 33 meteorites with a known orbit It is apparent how rare and important this. "Now, we know it's the construction debris of the planets, to borrow a phrase from Ed Scott of the University of Hawaii." "People used to say that meteorites like Gujba were the building blocks of the solar system," Humayun said. Based on chemical traces preserved in Gujba, the target planet might have been even larger than the asteroid 4 Vesta, one of the largest bodies in the asteroid belt with a diameter of about 326 miles or 525 kilometers. Oulton, Humayun and their collaborators argue that Gujba formed from the molten debris produced when a large metallic body smashed into another planet and both bodies were destroyed in the process. The roughly car-size asteroid safely flew by Earth, passing roughly 12,000 miles above Earth. Meteorologist Zach Covey determined the meteor was likely a chuck of the astroid 2021 GW4. The meteors large streak was spotted by people across central and south Florida. To get that type of formation, Gujba would have been involved in more than the equivalent of a solar system fender bender. At 10:16 pm Eastern Time, a Meteor lit up the sky over Florida. They inferred that Gujba formed from the debris of a collision between a parent planet that had both a crust and mantle, something that would only be found on a fairly large planet of the kind that is not seen today in the asteroid belt. Previously, scientists believed that Gujba was formed more or less from the dust of the solar system.īut, as Humayun and Oulton analyzed it, they discovered it had a far more complex geological history than previously thought. "We tried to elucidate a story about its origins through this science," said Oulton, who is now pursuing a doctoral degree at University of Colorado. Using sophisticated lasers and mass spectrometers at the FSU-headquartered National High Magnetic Field Laboratory, Humayun and Oulton conducted in-depth chemical analysis of the meteorite samples that shattered previous theories about when and how this meteorite had formed. ![]() Jonathan Oulton, a 2015 FSU graduate, working with Earth, Ocean & Atmospheric Science Professor Munir Humayun, studied the pieces of a meteorite called Gujba.
