We typically think of the Oort cloud as scattered ice balls floating far from the sun, yet still tied to it gravitationally. Occasionally, some wayward gravitational perturbation will knock one of ...

In a groundbreaking discovery, NASA's Pleiades supercomputer has revealed an unexpected spiral structure within the inner ...

Early in our Solar System’s history, bits of icy debris were scattered and then gradually coaxed into a spiral alignment in ...

The Oort cloud is a shell of icy objects that forms the very outskirts of our Solar System. Recently, a group of researchers ...

Even the little-understood Oort Cloud, at the outer edges of our solar system beyond view, has a partly spiral structure.

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 ...

Using a NASA supercomputer to run models, researchers led by SwRI astronomer David Nesvorny now believe that the Inner Oort cloud looks like a spiral disk, around 0.24 light-years across, with two ...

Most of the long-period comets in the Solar System come from the outer Oort Cloud. The inner region is much more stable. It's ...

Groundbreaking research reveals the Oort Cloud's shape as a spiral structure, challenging traditional beliefs about its random collection. NASA's Plei ...

The inner Oort cloud, between 1,000 and 10,000 AU from the sun, displays a spiral formation with arms that extend 15,000 AU.

Feb. 23 (UPI) --A shell of icy objects at the edge of the solar system known as the Oort cloud has a pair of spiral arms that resemble a miniature galaxy, new research suggests. Until now ...
