NASA scientists have discovered a spiral structure within the Oort Cloud that makes this distant region of our solar system resemble a miniature galaxy. This finding, revealed through computations on NASA’s Pleiades supercomputer, challenges conventional understanding of our solar system’s outermost boundary. The research, published February 16 on the preprint server arXiv, identified spiral arms stretching approximately 15,000 astronomical units (AU) in length within the inner Oort Cloud. While the paper awaits peer review, the implications for our understanding of solar system dynamics are significant. “We found that some comets in the inner Oort cloud form a long-lasting spiral structure,” … Continue reading NASA Supercomputer Reveals Hidden 15,000 AU Spiral in Oort Cloud, Billions of Comets Involved
