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.

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

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

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

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.

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 ...

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 ...
