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

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

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

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

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

"We found that some comets in the inner Oort cloud form a long-lasting spiral structure." Spirals are a repeating theme in ...

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 ...

But what the Oort cloud actually looks like and how it is affected by forces greater than just our solar system has remained somewhat of a mystery. A new paper posted to the arXiv preprint server ...

New research suggests the Oort Cloud may have a spiral structure like a mini galaxy. Supercomputer models reveal its mysterious shape, offering new insights into the edge of our solar system.

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.

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 ...

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 ...
