Space Daily | Aug 7, 2018 | ~ Researchers at the University of New Mexico uncover remnants of early solar system ~ | .. Scientists believe the solar system was formed some 4.6 billion years ago when a cloud of gas and dust collapsed under gravity possibly triggered by cataclysmic explosion from a nearby massive star or supernova. As this cloud collapsed, it formed a spinning disk with the sun in the center. Since then scientists have been able to establish the formation of the solar system piece by piece. Now, new research has enabled scientists from The University of New Mexico, Arizona State University and NASA's Johnson Space Center to add another piece to that puzzle with the discovery of the oldest-ever dated igneous meteorite. The research titled, Silica-rich volcanism in the Early Solar System Dated at 4.565 Ga, was published in Nature Communications. This research provides direct evidence that chemically evolved silica-rich crustal rocks were forming on planetsimals within the first 10 million years prior to the assembly of the terrestrial planets and helps scientists further understand the complexities of planet formation .. |
