Those "arms" resemble the elongated structures of a spiral galaxy, like our very own Milky Way. At an epic timescale "comparable to the age of the solar system," which is 4.6 billion years old ...

At the edge of our solar system, a host of large, icy bodies make up the Oort cloud, which appears to sport two spiral arms reminiscent of a disk-shaped galaxy. New research founded upon a simulation ...

NASA's Pleiades supercomputer has provided fresh insights into the Oort cloud – a vast, theoretical spherical shell of icy objects that surrounds our solar system. For a long time ...

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers discovered that the inner portion of the Oort cloud likely has spiral ...

Plate-tectonic processes have helped make ... to galactic traffic as the likely source of this pattern. Our Solar System and the spiral arms of the Milky Way are both spinning around the galaxy ...

Previous research has suggested that the Oort cloud contains remnants of the solar system's planets ... of debris may look like a mini galaxy with spiral arms. Researchers used a supercomputer ...

But as far as we know, no other bodies in the solar system exhibit plate tectonics today. Why is our world different? "We don't know for sure," Bradford Foley, a geodynamicist at Penn State ...
